Zero Tolerance for Fabrication or Suppression of Evidence: Legal and Professional Consequences
Forensic Scientists in Government Forensic Science
Laboratories
1. Introduction: Where Scientific Error Ends and
Misconduct Begins
In the
previous discussion, we talked about pressure on forensic scientists.
Today, I
want to take the discussion one step further.
There is
a fundamental difference between:
- making an honest scientific
error,
- making a negligent error,
- exercising poor scientific
judgment,
- and deliberately fabricating,
altering, concealing or suppressing evidence.
These
should not be treated as the same thing.
A
scientist can make an honest mistake.
A
scientist can misunderstand an instrument result.
A
scientist can make a calculation error.
A
scientist can misinterpret an observation.
These
errors need investigation, correction and, where necessary, corrective action.
But when
a scientist deliberately creates a false scientific record, changes an
observation, fabricates a result, deliberately destroys relevant evidence,
conceals an important finding, or knowingly presents a misleading conclusion,
we have entered an entirely different category.
That is
not simply a scientific mistake.
It is a
breach of professional responsibility and may also have serious legal
consequences.
The
central message of today's lecture is therefore quite simple:
There
must be zero tolerance for deliberate fabrication, falsification or suppression
of forensic evidence.
But I
want to discuss this in practical terms.
Because
in real laboratories, misconduct does not always begin with somebody saying:
“I am
going to fabricate evidence.”
Sometimes
it begins with:
“I'll
just correct this.”
Or:
“This
observation is probably not important.”
Or:
“There is
no need to mention this.”
Or:
“We know
the result already.”
Or:
“I'll
enter the result later.”
Or:
“The
instrument gave an unexpected result, so I'll repeat it until it looks right.”
Those
seemingly small decisions can become serious integrity failures.
2. What Do We Mean by
Fabrication?
The word fabrication
should be used carefully.
Fabrication
means creating something that did not actually exist and representing it as
genuine.
In
forensic science, examples could include:
- recording that an
examination was performed when it was not;
- inventing an analytical
result;
- creating a measurement that
was never obtained;
- entering a false observation
in laboratory notes;
- inventing instrument data;
- creating a false
chain-of-custody entry;
- claiming that a control
passed when it did not;
- reporting that a sample was
examined when it was never examined;
- inventing photographs or
comparison observations;
- creating a false record of
peer review.
For
example, suppose an examiner writes:
“Three
replicate analyses were performed and all produced the same result.”
But in
reality, only one analysis was performed.
That is
fabrication.
The
statement describes work that never happened.
3. Fabrication Is Different
from a Calculation Error
Consider
two situations.
Situation A
The
scientist performs three analyses.
The
actual results are:
2.31,
2.29 and 2.30.
While
preparing the report, the scientist accidentally writes:
2.31,
2.29 and 2.03.
That is
an error.
It may be
serious.
It may
need correction.
But there
was no intention to invent the examination.
Situation B
Only one
analysis was performed.
The
scientist writes:
“Three
replicate analyses were performed.”
That is
fabrication.
The
distinction is important because the response should be proportionate.
We should
not create a culture where scientists are terrified to report honest mistakes.
If
scientists fear that admitting an error will automatically be treated as
misconduct, they may become tempted to conceal errors.
That
would make the laboratory less safe.
4. Falsification
A related
concept is falsification.
Falsification
involves manipulating or altering genuine information so that it represents
something different from what actually occurred.
For
example:
- changing an analytical
value;
- deleting an inconvenient
result;
- altering a photograph;
- modifying an instrument
output;
- changing a date;
- changing a sample
identification;
- altering laboratory notes;
- selectively recording
observations;
- changing a result after the
fact without preserving the original record.
Here,
something real existed, but the record has been deliberately changed.
5. Suppression of Evidence
Suppression
can be less obvious.
Suppression
occurs when relevant information is deliberately withheld, concealed or
excluded in a manner that is intended to prevent it from being considered.
Forensic
examples could include:
- deliberately not reporting a
relevant finding;
- hiding a result that
contradicts the expected conclusion;
- failing to disclose a failed
quality-control test when it affects the validity of the examination;
- deliberately withholding an
alternative interpretation;
- destroying relevant
laboratory records;
- refusing to disclose a
significant limitation;
- removing an unfavorable
observation from the case file.
Suppression
does not necessarily mean physically destroying evidence.
Sometimes
it is simply:
“I know
this result exists, but I am not going to tell anyone.”
That can
be equally serious.
6. An Important
Distinction: Not Every Omission Is Suppression
We must
be careful here.
A
scientific report cannot contain every observation made during every
examination.
Scientists
routinely decide which observations are relevant to the conclusion.
That is
normal scientific reporting.
Suppression
becomes a serious integrity issue when a scientist deliberately withholds
information that is materially relevant, because disclosure would affect the
interpretation or outcome of the case.
For
example:
If an
examiner performs 100 routine measurements and reports the relevant summary
statistics, that is not suppression.
But if an
examiner obtains a result that contradicts the reported conclusion and
deliberately removes it because:
“It will
create problems for the prosecution,”
that is
very different.
The
intention and materiality matter.
7. The Three Questions to
Ask
Whenever
there is uncertainty about whether something should be included or preserved,
ask three questions:
1. Is the information scientifically relevant?
2. Could it affect interpretation of the evidence?
3. Am I excluding it because of a legitimate
scientific reason—or because it is inconvenient?
That
third question is particularly important.
If the
real reason is:
“It does
not help the case,”
stop.
That is
not a scientific reason.
8. Why Zero Tolerance Is
Necessary
Why
should we be particularly strict about fabrication and suppression in forensic
science?
Because
forensic evidence enters a system where other people rely on it.
A false
laboratory result can influence:
- an investigation,
- an arrest,
- a search,
- a charge sheet,
- a prosecution,
- bail proceedings,
- a trial,
- conviction,
- acquittal,
- sentencing,
- appeal,
- and public perception.
A
laboratory report may be only a few pages long.
But the
consequences of those pages can continue for years.
That is
why the standard has to be extremely high.
9. The Forensic Scientist Has
a Different Kind of Power
A
forensic scientist may not carry a weapon.
A
scientist may not arrest anybody.
A
scientist may not conduct the investigation.
But a
laboratory report can influence decisions affecting a person's liberty and
reputation.
That creates
responsibility.
The
scientist has what we might call evidentiary power.
With that
power comes a duty:
Do not
manufacture evidence.
Do not
manipulate evidence.
Do not
hide material evidence.
Do not
present speculation as scientific fact.
10. The Most Important
Rule: Never Manufacture a Result
This
sounds so obvious that some people may wonder why we need to say it.
We need
to say it because the circumstances that lead to fabrication can be
surprisingly ordinary.
Imagine:
- a court date is approaching;
- the report is overdue;
- the investigator is calling
repeatedly;
- the laboratory has a
backlog;
- the scientist forgot to
perform one required step;
- the original sample is no
longer available;
- the instrument data are
missing.
The
temptation may be:
“I'll complete
the paperwork and sort it out later.”
That is
dangerous.
If the
examination did not happen, the record must not say that it happened.
The
scientifically correct answer may be inconvenient.
But
inconvenience is not a justification for fabrication.
11. “I'll Do It Later” Can
Become a Serious Problem
Consider
this hypothetical example.
A
scientist receives ten samples.
The
scientist examines eight.
Two are
accidentally left pending.
The
report deadline arrives.
The
scientist enters results for all ten because:
“I know
what the remaining two are likely to show.”
This is
unacceptable.
Even if
the scientist is 99 percent confident about the result, the examination was not
performed.
The
correct action is:
“Two
samples remain pending.”
Or:
“The
examination could not be completed because…”
A
forensic report must describe what was actually done, not what the
scientist believes would probably have happened.
12. Never Backdate a
Scientific Record
Another
common danger is retrospective documentation.
Suppose a
scientist performs an examination on 20 August.
The
record is created on 24 August.
That is
not automatically misconduct if the laboratory system allows retrospective
documentation.
But the
scientist must accurately record when the examination occurred and when the
record was created.
What
becomes problematic is changing dates to create the appearance that something
happened earlier.
For
example:
“Examination
completed: 18 August”
when it
actually occurred on 24 August.
Why does
this matter?
Because
dates can affect:
- chain of custody,
- instrument availability,
- sample condition,
- court deadlines,
- quality-control records,
- accountability.
A date is
a scientific record, not decoration.
13. Chain of Custody Is
Part of Scientific Integrity
Sometimes
scientists think:
“Chain of
custody is the police department's responsibility.”
Not
entirely.
The
laboratory must accurately document what happens to evidence while it is under
laboratory control.
That
includes:
- receipt,
- opening,
- examination,
- storage,
- transfer,
- resealing,
- return.
A false
entry is not a minor administrative problem.
If the
laboratory record says:
“Seal
intact”
when the
seal was actually damaged,
that is a
serious issue.
The
correct response is to document the actual condition.
14. “The Seal Was Slightly
Damaged—Should I Mention It?”
This is
an excellent training question.
Suppose
the exhibit arrives with a damaged or questionable seal.
The
scientist thinks:
“It
probably happened during transportation.”
Maybe it
did.
But
unless you know that, do not invent an explanation.
Record:
“The seal
was received in the following condition…”
Then
follow the laboratory procedure.
The
scientist's job is not to create a convenient story about how the damage
occurred.
The
scientist's job is to document what was observed.
15. The Difference Between
Observation and Explanation
This
distinction is extremely useful.
Observation:
“The seal
was partially open.”
Explanation:
“The seal
was accidentally opened during transportation.”
The first
may be directly observed.
The
second requires knowledge about how it happened.
Do not
turn assumptions into observations.
Similarly:
Observation:
“A brown
stain was present.”
Interpretation:
“The
stain is blood.”
The
second requires examination.
And:
Observation:
“The DNA
profile is consistent with…”
Legal conclusion:
“The
accused committed the offence.”
That last
step may be outside the scientific conclusion.
Every
forensic scientist should know exactly where one category ends and the next
begins.
16. Fabrication Can Occur
in Digital Records Too
Today,
much forensic work is digital.
That
creates additional risks.
Examples
include:
- changing a spreadsheet
value;
- editing an image without
preserving the original;
- modifying metadata;
- deleting an original
instrument file;
- changing timestamps;
- overwriting a database
entry;
- copying an old result into a
new case;
- creating a report from a
previous case and failing to update all identifiers.
Some of
these may happen accidentally.
But
deliberately changing digital records to alter the evidentiary picture is
serious misconduct.
Digital
evidence requires the same principle as physical evidence:
Preserve
the original and maintain traceability of changes.
17. The “Copy-Paste”
Problem
This
deserves special attention in government laboratories.
Scientists
often work with standard report formats.
Templates
are useful.
But
copy-paste can produce serious errors.
For
example:
Case A:
“Male DNA
profile…”
Case B:
“Female
DNA profile…”
A
previous paragraph is copied and not fully corrected.
Now the
report contains information from another case.
This may
be an honest mistake.
But if
the scientist notices the error and deliberately leaves it because:
“It is
close enough,”
the
problem becomes much more serious.
The
solution is:
- use controlled templates;
- verify case numbers;
- verify sample identifiers;
- perform technical review;
- use checklists for high-risk
reports.
18. The “Expected Result”
Problem
Suppose
an investigator tells the scientist:
“We
strongly suspect this is the poison.”
The
scientist performs the test.
The
result is negative.
The
scientist thinks:
“Maybe
the reagent was not good.”
So
another test is performed.
Negative
again.
Another
method is tried.
Negative
again.
At some
point, the question becomes:
Are we
performing scientifically justified additional examinations, or are we simply
searching until we obtain the desired result?
This is
an important distinction.
19. Repeating a Test Is Not
Wrong
We should
not create the impression that repeating an analysis is suspicious.
Repeat analysis
may be completely appropriate because of:
- quality-control
requirements,
- instrument performance,
- unexpected result,
- sample heterogeneity,
- technical error,
- insufficient signal,
- confirmation requirements.
The
problem is not repetition.
The
problem is selective repetition until the preferred result appears, while
ignoring or hiding the previous results.
That is
where integrity can fail.
20. A Good Laboratory
Record Shows the Journey
Suppose
five analyses are performed:
- negative,
- negative,
- inconclusive,
- positive,
- confirmation positive.
A proper
record should allow the laboratory to understand why the final conclusion was
reached.
The
answer should not simply be:
“Final
result: positive.”
There
should be a scientific explanation for the sequence.
If
earlier results are relevant, they should not disappear merely because the
final result is more convenient.
21. Selective Reporting
Selective
reporting is one of the subtle forms of suppression.
Imagine a
scientist obtains:
Test A:
positive
Test B: negative
Test C: positive
The
scientist reports only:
“Two
tests were positive.”
That may
be misleading if Test B is relevant to interpretation.
The
scientist must consider:
Is the
negative result scientifically relevant?
If yes,
it must be addressed appropriately.
The
purpose of reporting is not to count supporting results.
It is to
accurately communicate the evidence.
22. What If the Unfavorable
Result Is Due to a Known Technical Problem?
This is
where professional judgment matters.
Suppose
one test failed because:
- a control failed,
- the instrument
malfunctioned,
- the sample was contaminated,
- the reagent was invalid,
- the procedure was not
followed.
That
result may not be scientifically interpretable.
It does
not necessarily need to be treated as substantive evidence against the final
conclusion.
But the
technical problem must be documented.
The
correct approach is not:
“Delete
the bad result.”
It is:
“Document
why the result was invalid or unsuitable for interpretation.”
That
distinction is fundamental.
23. A Scientist Should
Never “Clean Up” Data
The
phrase “clean up the data” can be dangerous.
Data
cleaning is legitimate in many scientific contexts.
But in
forensic science, any transformation of original evidence or data must be:
- justified,
- documented,
- reproducible,
- traceable.
Do not
alter the original simply because it looks untidy.
Keep the
original.
Create a
documented working copy if necessary.
Record
what was done.
That
protects both the evidence and the scientist.
24. Suppression Can Begin
with a Conversation
Consider
this conversation:
Investigator:
“Did you
find anything else?”
Scientist:
“There
was another finding, but it is probably not important.”
Investigator:
“Then
don't mention it.”
Scientist:
“Okay.”
This may
take less than one minute.
But it
can become a serious problem later.
The
better response is:
“There is
an additional finding. I will determine its relevance during interpretation and
report it appropriately.”
Do not
let informal conversation decide what becomes part of the scientific record.
25. The Importance of
Exculpatory Evidence
One of
the most important principles in forensic science is that evidence does not
become irrelevant simply because it helps the accused.
If DNA
excludes a suspect, that result matters.
If a
fingerprint does not support the suspected individual, that matters.
If a
questioned document is genuine rather than forged, that matters.
If a drug
sample does not contain the alleged substance, that matters.
The
forensic scientist must not think:
“My job
is to help prove the case.”
The job
is to determine what the evidence shows.
Evidence
that weakens a prosecution theory may be scientifically important.
Evidence
that weakens a defence theory may also be scientifically important.
The
standard should be the same.
26. The Legal System
Depends on Full and Accurate Evidence
Courts
make decisions based on evidence presented to them.
If
material scientific information is deliberately hidden, the court may make a
decision without knowing something important.
That is
why suppression can be especially serious.
It
affects not only the laboratory.
It
affects the fairness of the entire process.
The
scientist may never know the ultimate consequence.
A hidden
finding could influence:
- whether someone is arrested,
- whether someone is charged,
- whether bail is granted,
- whether a person is
convicted,
- whether another suspect is
overlooked.
That is
why a seemingly small omission can have a large effect.
27. A Famous Lesson: FBI
Laboratory Review
A useful
historical example comes from the FBI Laboratory.
Following
concerns about forensic practices, the U.S. Department of Justice Office of the
Inspector General conducted extensive reviews of the FBI Laboratory's work.
The 1997
OIG report examined issues including allegations of inaccurate laboratory
reports, misleading testimony, inadequate documentation and quality-control
concerns. It resulted in recommendations relating to laboratory accreditation,
procedures, documentation, reporting and oversight.
The
important lesson for us is not to focus on individual blame.
The
larger lesson is:
When a
laboratory's scientific records are not sufficiently controlled, the problem
can remain hidden for years.
Good
intentions are not enough.
Traceability
is necessary.
28. The Hair Microscopy
Experience
Another
important example concerns historical forensic hair-comparison testimony in the
United States.
Following
later DNA testing and concerns about earlier testimony, the FBI undertook a
large review of cases involving microscopic hair comparison.
The U.S.
Department of Justice Inspector General reported that the review ultimately
involved more than 20,000 cases.
The
significance of this example is not that hair examiners were necessarily
deliberately fabricating evidence.
In many
instances, the issue involved overstatement of scientific conclusions.
That
distinction is important.
It shows
that forensic integrity is broader than:
“Don't
invent evidence.”
It also
requires:
“Do not
represent the evidence as stronger than it actually is.”
29. Three Levels of
Seriousness
For
training purposes, I find it useful to distinguish three levels.
Level 1: Honest error
Example:
Wrong
number entered accidentally.
Response:
- correct,
- document,
- review,
- learn.
Level 2: Serious negligence
Example:
Required
quality-control step was knowingly skipped because the scientist was in a
hurry.
Response:
- investigate,
- assess impact,
- corrective action,
- possible disciplinary
consequences depending on circumstances.
Level 3: Deliberate misconduct
Example:
Scientist
knowingly creates a false analytical result to support a case.
Response:
- immediate investigation,
- preservation of records,
- appropriate
administrative/disciplinary action,
- possible professional and
criminal consequences.
These
categories should not be blurred.
30. Why Intent Matters
Suppose a
scientist writes the wrong date.
That does
not automatically mean:
“The
scientist falsified the record.”
We must
determine:
- Was it accidental?
- Was it corrected?
- Was the original record
preserved?
- Did the scientist benefit
from the change?
- Was there an attempt to
conceal it?
- Was the mistake repeated?
- Did the scientist knowingly
misrepresent what happened?
Investigation
should be evidence-based.
Zero
tolerance for fabrication does not mean zero tolerance for honest mistakes.
It means zero
tolerance for deliberate dishonesty.
31. But “I Didn't Mean To”
Is Not Always Enough
At the
same time, intention cannot become an excuse for repeated reckless behaviour.
Suppose a
scientist repeatedly:
- fails to label samples,
- ignores quality-control
failures,
- signs reports without
reviewing them,
- alters records after the
fact,
- disregards warnings.
Each
individual event may be explained as an “accident.”
But
repeated conduct may demonstrate serious negligence.
Professional
responsibility includes taking reasonable care.
32. When Does Negligence
Become Serious?
Consider
a scientist who knows:
“The
instrument calibration expired last week.”
The
scientist continues using it without checking the applicable procedure.
A result
is obtained.
The
scientist reports it anyway.
That is
different from accidentally overlooking a calibration date.
The
scientist knew there was a problem.
The
question becomes:
Did the
scientist knowingly disregard a requirement that could affect the validity of
the result?
That can
have serious professional consequences.
33. Don't Hide
Quality-Control Failures
Suppose:
Positive
control failed.
The
scientist says:
“I'll
just repeat the sample.”
That may
or may not be appropriate depending on the method.
The
proper question is:
“What
does the SOP require when the control fails?”
Follow
the procedure.
Do not
simply repeat until the control passes and then pretend the original failure
never happened.
A failed
control is information about the analytical process.
34. A Quality-Control
Failure Is Not an Embarrassment
This is a
cultural issue.
If
scientists believe:
“A failed
control will make our section look bad,”
they may
be tempted to hide it.
Instead,
the culture should be:
“A failed
control tells us something important. Let's determine what happened.”
A
laboratory that detects failures is often safer than one that reports perfect
results all the time.
Perfect
results in a complicated laboratory should actually make us ask questions.
35. The Pressure to Produce
“100 Percent” Results
Sometimes
management or outsiders implicitly expect:
“Why are
so many of your results inconclusive?”
That can
create dangerous incentives.
If
scientists are rewarded for producing more positive identifications, they may
gradually become more willing to interpret ambiguous evidence as conclusive.
Performance
indicators should therefore be designed carefully.
A
forensic laboratory should not measure success simply by:
Number of
positive results.
Better
measures include:
- turnaround time,
- quality-control compliance,
- proficiency testing,
- error detection,
- review quality,
- backlog reduction,
- appropriate reporting,
- corrective actions.
36. A Laboratory Should
Never Reward the Wrong Behaviour
Suppose
two scientists are compared.
Scientist
A:
- produces many strong
conclusions,
- rarely reports limitations,
- rarely calls anything
inconclusive.
Scientist
B:
- reports limitations,
- uses cautious conclusions,
- identifies insufficient
evidence,
- occasionally reports
inconclusive results.
If
management automatically considers Scientist A “more productive,” it may
unintentionally encourage overstatement.
The
scientifically correct result is not always the most dramatic result.
37. Pressure from the
Investigator Can Lead to Suppression
Imagine
an investigator says:
“Don't
include that negative result in the report. We have other evidence.”
The
scientist may think:
“The
other evidence is strong, so this result isn't necessary.”
That is
not the scientist's decision unless the omission is scientifically justified
and consistent with reporting requirements.
The
question is:
Is the
result relevant to the scientific interpretation?
If yes,
it should not disappear simply because other evidence exists.
38. What If the
Investigator Says, “It Will Confuse the Court”?
This is
another common argument.
The
response should be:
“We can
explain the finding clearly. Scientific complexity should not be removed by
omitting relevant information.”
The
forensic scientist should not deliberately simplify the evidence by deleting
inconvenient facts.
If a
finding requires explanation, explain it.
39. What If the Scientist
Is Asked to Destroy Old Records?
This is a
serious situation.
Records
should be destroyed only according to:
- approved retention
schedules,
- laboratory policy,
- legal requirements,
- archival requirements,
- quality-management
procedures.
A
scientist should not independently destroy records because:
“This
case is over.”
or:
“We don't
need these anymore.”
Especially
sensitive are:
- original instrument data,
- raw analytical records,
- photographs,
- notes,
- worksheets,
- chain-of-custody documents,
- review records.
If there
is a legal hold, investigation or ongoing proceedings, destruction may have
serious consequences.
40. Do Not Delete Digital
Evidence to “Save Space”
This is
increasingly relevant.
Laboratories
accumulate:
- photographs,
- chromatograms,
- electropherograms,
- videos,
- instrument files,
- extraction files,
- metadata,
- case databases.
Deleting
files without authorization can destroy evidentiary information.
If
storage is a problem, the solution is:
storage
management,
not:
uncontrolled
deletion.
41. The Danger of Personal
Devices
Scientists
should be careful about transferring case data to:
- personal laptops,
- personal phones,
- private cloud storage,
- personal email,
- USB devices.
There may
be legitimate operational circumstances in which data must be transferred.
But it
should occur through authorized systems.
Unauthorized
copying creates risks involving:
- alteration,
- loss,
- confidentiality,
- access,
- chain of custody,
- accidental deletion.
42. “I Only Wanted to Help”
Many
professional failures begin with good intentions.
A
scientist thinks:
“The
investigator needs the report urgently.”
So the
scientist skips a review.
Another
thinks:
“The
court will not understand this technical limitation.”
So the
limitation is removed.
Another
thinks:
“The
accused is obviously guilty.”
So an
ambiguous finding is described more strongly.
Another
thinks:
“My
senior will be embarrassed if I point out the mistake.”
So the
error is left uncorrected.
Good
intentions do not make bad scientific practice acceptable.
But they
help us identify where training and systems are needed.
43. The Scientist Must
Resist the “Case Theory”
Suppose
everyone believes:
Suspect A
→ Weapon B → Bullet C → Victim D.
The
laboratory receives the weapon and bullet.
The
scientist should not start from:
“How do I
prove A used B?”
Start
with:
“What can
I determine about the relationship between B and C?”
That
scientific question is narrower.
And
narrower questions are often safer.
44. Never Manufacture a
Link Between Evidence and Person
This is
particularly important.
The
laboratory may establish:
Sample A
and Sample B have the same DNA profile.
That does
not automatically establish:
Person X
committed the crime.
The
laboratory may establish:
The
bullet has characteristics consistent with the submitted firearm.
That does
not automatically establish:
The
accused fired the weapon during the offence.
The
laboratory should not create links that the scientific examination itself did
not establish.
45. The “Missing Sample”
Problem
Suppose
the investigating agency asks:
“Can you
report on the sample?”
But the
sample is missing.
There may
be enormous pressure to proceed.
The
scientist must not report:
“The
sample was examined and found negative.”
if the
sample was never examined.
The
correct report may be:
“The
examination could not be performed because the required exhibit was not
available.”
This is
inconvenient.
It may
anger somebody.
But it is
scientifically accurate.
46. Never Fill Gaps with
Assumptions
Forensic
science often involves incomplete evidence.
The
temptation is to fill the gaps.
For
example:
“The
missing seal was probably damaged during transport.”
“The
absent control probably would have passed.”
“The
sample probably came from the same person.”
“The
instrument probably gave the same result.”
Words
such as:
- probably,
- obviously,
- certainly,
- must have,
should
make us stop.
Ask:
What
evidence do I actually have?
47. The Difference Between Professional
Judgment and Guessing
Forensic
scientists must exercise judgment.
But
judgment must be grounded in:
- validated methods,
- observations,
- reference data,
- accepted criteria,
- experience,
- scientific reasoning.
Guessing
is different.
If
evidence is insufficient, say so.
A
scientifically honest:
“Cannot
be determined”
is better
than a confident guess.
48. The Consequences for
the Scientist
Now we
come to the second part of today's topic:
What
happens when fabrication or suppression is discovered?
The
consequences can occur at several levels.
Professional consequences
- loss of credibility,
- loss of responsibility,
- adverse performance
assessment,
- suspension,
- disciplinary proceedings,
- demotion or other service
consequences,
- dismissal, depending on applicable
rules.
Scientific consequences
- withdrawal or correction of
reports,
- review of previous cases,
- loss of laboratory
confidence,
- additional quality controls,
- reassessment of the
scientist's work.
Legal consequences
Depending
on the facts and jurisdiction:
- investigation,
- prosecution,
- evidentiary challenges,
- contempt-related
consequences,
- offences involving false
records or evidence,
- civil liability,
- other statutory
consequences.
The exact
legal provisions will vary according to the country, state and service
framework.
But the
principle is universal:
A
forensic scientist does not have immunity from the consequences of deliberate
misconduct simply because the misconduct occurred in a scientific laboratory.
49. The Damage Extends
Beyond One Scientist
Suppose
one scientist fabricates evidence.
The
damage is not limited to that person.
Investigators
may have relied on it.
Prosecutors
may have relied on it.
Courts
may have relied on it.
Other
scientists may have signed review documents.
The
laboratory's credibility may be questioned.
Past
cases may need examination.
The
public may begin asking:
“Can we
trust the laboratory at all?”
That is
why misconduct in one case can become an institutional crisis.
50. The Domino Effect
Consider
this chain:
False
observation
↓
False
laboratory report
↓
Investigator
relies on report
↓
Charge or
prosecution strategy changes
↓
Court
hears the evidence
↓
Defence
challenges evidence
↓
Scientific
records are examined
↓
Falsehood
is discovered
↓
Previous
cases are reviewed
↓
Laboratory
credibility suffers
A small
dishonest act can therefore become much larger.
51. The Courtroom Is Where
the Scientific Record Is Tested
A
scientist may think:
“Nobody
will check the raw data.”
That is a
dangerous assumption.
In a
serious case, lawyers may ask:
- What exactly did you
examine?
- When did you examine it?
- Who handled it?
- What instrument did you use?
- What were the controls?
- What were the raw results?
- Did you repeat the analysis?
- Were there contradictory
results?
- Who reviewed your work?
- When was the report
prepared?
- Did you alter the data?
- Where are the original
records?
If the
laboratory record is incomplete, the scientist may struggle to explain what
happened.
52. Never Assume That a
False Statement Will Remain Hidden
Digital
systems have made concealment more difficult.
Modern
laboratories may have:
- instrument audit trails,
- laboratory information
systems,
- file timestamps,
- access logs,
- automated backups,
- email records,
- review histories,
- metadata.
Even
paper records can be compared with:
- instrument logs,
- attendance records,
- sample movement records,
- CCTV where applicable,
- other scientists' notes.
A
scientist should therefore never think:
“I'll
change this quietly.”
The
scientific record often contains more information than the final report.
53. Witness Testimony Can
Expose Problems
Suppose a
scientist says:
“I
performed three examinations.”
A
colleague says:
“There
were only two.”
Or the
instrument log shows one.
Or the
laboratory notebook shows another date.
Contradictions
can quickly become serious.
The
lesson is simple:
Your
scientific record should tell the same story as your testimony.
54. Giving False Testimony
Is a Separate Problem
The
problem does not end with the laboratory report.
A
scientist may later be called to court.
If the
scientist knowingly gives false evidence or knowingly repeats a fabricated
conclusion, the misconduct may become even more serious.
The
correct response when asked about something you do not remember is:
“I do not
recall.”
Not:
“Yes,
definitely.”
If the
record says something different from your memory, say:
“I would
like to refer to the contemporaneous record.”
That is
professional.
55. Do Not Guess in Court
This is a
very practical rule.
Lawyers
may ask:
“Would
you agree that…?”
“Isn't it
possible that…?”
“Surely
you must have…”
Do not
agree simply because the question sounds reasonable.
Answer
the scientific question.
Useful
phrases include:
“I cannot
say that from the examination.”
“That is
outside the scope of my examination.”
“I would
need to refer to my records.”
“The data
do not allow me to reach that conclusion.”
“That is
possible, but I did not examine that question.”
These are
legitimate expert responses.
56. Do Not Expand Your
Expertise Under Pressure
Suppose
you are a toxicologist.
A lawyer
asks:
“Based on
the toxicology findings, can you say whether the accused intended to kill the
victim?”
That may
be outside your expertise.
Do not
answer merely because you are an expert witness.
Say:
“That is
not a conclusion I can draw from my toxicological examination.”
Knowing
the boundary of your expertise is part of professional integrity.
57. The Professional
Consequence: Loss of Trust
Even
where criminal prosecution does not occur, deliberate dishonesty can
permanently damage a scientific career.
Think
about what happens to the scientist's professional identity.
Can
colleagues trust the results?
Can the
scientist testify credibly?
Can the
laboratory assign sensitive cases?
Can the
scientist supervise juniors?
Can other
institutions rely on the scientist's work?
Scientific
reputation takes years to build.
It can
disappear through one dishonest act.
58. But Do Not Create a
Culture of Fear
This is
important for laboratory heads.
If the
message becomes:
“One
mistake and your career is finished,”
scientists
may hide mistakes.
The
correct message is:
“We will
help you correct honest mistakes. We will not tolerate deliberate dishonesty.”
That
distinction creates a healthier environment.
Scientists
should feel safe reporting:
- errors,
- near misses,
- contamination,
- failed controls,
- incorrect entries,
- sample problems.
They
should not feel safe fabricating or concealing them.
59. Near-Miss Reporting
A useful
laboratory culture encourages reporting of near misses.
For
example:
A
scientist almost reported the wrong sample number but caught the mistake during
review.
That is
not a failure.
It is an
opportunity to ask:
Why was
the error possible?
Maybe:
- labels were too similar,
- the case numbers were
difficult to read,
- the software interface was
confusing,
- there was inadequate
separation between cases.
Fix the
system.
That is
much better than simply saying:
“Be more
careful.”
60. Root-Cause Analysis
When
something goes wrong, ask:
“Why did
this happen?”
Not only:
“Who did
it?”
Suppose a
report contained the wrong case number.
Why?
Perhaps:
- The number was entered
manually.
- The system had no barcode.
- There was no second-person
verification.
- The report template
automatically retained old identifiers.
Now the
laboratory can fix the system.
Blaming
the scientist alone may not prevent recurrence.
61. But Root-Cause Analysis
Is Not an Excuse
We should
not go to the other extreme.
If
someone deliberately fabricates evidence, saying:
“The
system allowed it”
does not
remove personal responsibility.
Both
levels must be examined:
Individual responsibility
What did
the person knowingly do?
Institutional responsibility
Why was
the system unable to detect or prevent it?
Both
questions matter.
62. The Role of Supervisors
Supervisors
should watch for warning signs.
Not proof
of misconduct—but warning signs.
For
example:
- unexplained changes in
records;
- missing raw data;
- repeated failure to provide
original worksheets;
- unusually perfect results;
- resistance to peer review;
- repeated unexplained
corrections;
- unexplained differences
between instrument data and reports;
- reluctance to allow another
examiner to review work;
- unusually strong conclusions
from weak evidence.
These
should trigger questions, not accusations.
63. The “Perfect Scientist”
Problem
A
scientist who reports:
- no mistakes,
- no failed controls,
- no inconclusive results,
- no contamination,
- no technical difficulties,
may
appear excellent.
But real
scientific work contains uncertainty and occasional problems.
A
laboratory should therefore be careful about equating:
“Never
reports a problem”
with
“Never
has a problem.”
Sometimes
the opposite may be true.
64. The Role of Internal
Audit
Internal
audits can identify:
- missing records,
- inconsistent dates,
- unexplained changes,
- incomplete review,
- uncontrolled documents,
- deviations from SOPs,
- weak traceability.
Audits
should not be treated as punishment.
They are
an additional layer of protection.
A
scientist should welcome a system that can demonstrate:
“This
work was properly performed.”
65. External Proficiency
Testing
Proficiency
testing is another safeguard.
It helps
determine whether scientists can produce appropriate results using:
- known samples,
- blind samples,
- external comparison
exercises.
If a
scientist performs poorly, the answer should initially be:
investigate,
understand, correct, retrain, reassess.
Not:
immediately
label the scientist dishonest.
Again,
distinguish error from misconduct.
66. What Should Happen When
Deliberate Misconduct Is Suspected?
A
laboratory should have a defined procedure.
At a
general level:
Step 1
Preserve
the relevant records and evidence.
Step 2
Prevent
further alteration or destruction of records.
Step 3
Separate
fact-finding from assumptions.
Step 4
Notify
the appropriate authority.
Step 5
Conduct a
fair investigation.
Step 6
Assess
the scientific impact.
Step 7
Determine
whether other cases may be affected.
Step 8
Take
appropriate administrative, professional or legal action.
Step 9
Correct
or withdraw affected reports where required.
Step 10
Identify
systemic weaknesses and correct them.
This is
much better than reacting emotionally.
67. Why Case Review May Be
Necessary
Suppose a
scientist is proven to have fabricated one report.
The
laboratory should ask:
“Could
other reports be affected?”
That does
not mean:
“All of
the scientist's work is false.”
It means
the laboratory needs a risk-based review.
Possible
questions:
- How many cases did the
scientist handle?
- During what period?
- What type of examinations?
- Were there co-examiners?
- Were there independent
reviews?
- Are raw data available?
- Are there complaints?
- Are there unusual patterns?
The
review should be systematic.
68. Do Not Destroy the
Scientist's Other Work Without Evidence
Again,
fairness matters.
Once
misconduct is discovered, there can be a temptation to assume:
“Everything
this person ever did must be wrong.”
That is
not scientifically justified.
Each
affected case should be evaluated according to evidence.
This is
important because the objective is not revenge.
The
objective is to restore confidence in the scientific record.
69. The Difference Between
Retraction and Concealment
If a
laboratory discovers that a report is wrong, it may need to:
- issue a correction,
- issue an amended report,
- withdraw a report,
- notify relevant authorities,
- conduct a review.
That is
not an admission of institutional failure in the negative sense.
It is
part of scientific accountability.
A
laboratory becomes less trustworthy when it hides mistakes.
It
becomes more trustworthy when it corrects them transparently.
70. The Scientist's Duty
When a Colleague Is Doing Something Wrong
This is a
difficult issue.
Suppose
you see a colleague deliberately changing results.
What
should you do?
First, do
not join them.
Second,
do not help conceal it.
Third, preserve
what is appropriate and permitted under laboratory procedure.
Fourth,
use the established reporting or escalation mechanism.
Do not
turn it into:
“I will
expose you publicly.”
Use
professional channels.
The
purpose is to stop the misconduct and protect the integrity of the evidence.
71. “He Is My Friend” Is
Not a Scientific Argument
Personal
relationships can make reporting difficult.
The
colleague may be:
- a friend,
- a mentor,
- a senior,
- a respected scientist,
- someone close to retirement.
But the
question should be:
“What is
happening to the scientific record?”
If the
record is being deliberately falsified, friendship does not change the nature
of the act.
72. What If the Colleague
Says, “Everyone Does It”?
This is a
warning sign.
Statements
such as:
“Everybody
adjusts the numbers.”
“This is
how we manage backlog.”
“No one
checks these things.”
“The
court doesn't understand technical details.”
“Just
make the report stronger.”
should
never become normalized.
Once a
laboratory accepts small dishonest practices as routine, larger misconduct
becomes easier.
73. Normalization of
Deviance
There is
a useful organizational concept called normalization of deviance.
A
practice begins as an exception.
Then it
is repeated.
Then
nobody objects.
Eventually
it becomes:
“This is
how we do things.”
For
example:
First
time:
“We
skipped the second review because it was an emergency.”
Second
time:
“Again,
because the court deadline was close.”
After six
months:
“We don't
normally do second review for urgent cases.”
The
exception has become the procedure.
Laboratory
managers must watch for this.
74. Emergencies Do Not
Suspend Scientific Integrity
A genuine
emergency may justify:
- prioritization,
- additional staffing,
- alternative validated
methods,
- accelerated review,
- extended working hours.
It does
not justify:
- inventing results,
- deleting records,
- hiding findings,
- falsifying dates,
- signing work that was not
performed.
The
correct principle is:
Emergency
procedures may change the workflow; they must not create false evidence.
75. Political Cases Need
More Documentation, Not Less
When a
case is politically sensitive, scientists sometimes want to keep things simple.
I would
suggest the opposite.
The more
sensitive the case:
- the clearer the documentation,
- the stronger the review,
- the better the record
preservation,
- the more careful the
communication.
Do not
treat political sensitivity as a reason to bypass procedure.
Treat it
as a reason to follow procedure particularly carefully.
76. High-Profile Cases
Should Not Have “Special Science”
A
politically sensitive case should not have a different scientific standard.
You may
have:
- special security,
- special reporting channels,
- faster processing,
- senior review.
But you
should not have:
“Special
interpretation.”
The same
scientific criteria should apply.
77. A Case Study: The
Missing Negative Finding
Let us
take a realistic hypothetical example.
A
suspected narcotic substance is submitted.
The
investigator says:
“It is
definitely heroin.”
The
scientist's initial screening gives a result consistent with heroin.
A
confirmatory test gives an unexpected negative result.
The
investigator says:
“The
first test was positive. Just report heroin.”
What
should happen?
The
scientist should not simply choose the favorable result.
The
appropriate response is:
- Verify the tests.
- Check controls.
- Check sample identity.
- Check instrument
performance.
- Repeat or confirm according
to SOP.
- Determine whether the
conflicting result can be scientifically resolved.
- Document the findings.
- Report the conclusion
supported by the complete examination.
The
negative result cannot disappear merely because it is inconvenient.
78. Case Study: DNA Mixture
Suppose a
DNA mixture contains contributions from several individuals.
The
investigator says:
“The
accused is definitely in the mixture.”
The
scientist examines the data and finds that the interpretation is complex.
The
correct response may be:
“The
available data do not permit a definitive inclusion/exclusion under the applicable
interpretation criteria.”
The
investigator may be disappointed.
But the
scientist must not alter the interpretation simply to produce a clearer answer.
Mixture
interpretation is precisely the kind of area where careful methodology,
validation and appropriate statistical interpretation matter.
79. Case Study: Firearms
Evidence
Suppose a
bullet has limited markings.
The
examiner cannot reach a conclusive association.
The
investigator says:
“But the
weapon was recovered from the accused.”
That fact
may be relevant to the investigation.
But it
does not manufacture microscopic markings on the bullet.
The
examiner should report what the firearm evidence supports.
The
investigator can use other evidence to build the case.
That is
how the system should work.
80. Case Study: Questioned
Documents
Suppose a
signature is suspicious.
The
investigator says:
“The
accused has already confessed.”
The
examiner should still independently examine:
- line quality,
- movement,
- pen pressure,
- proportions,
- letter formation,
- variation,
- natural writing
characteristics,
- disguise indicators,
- comparison standards.
A
confession does not change the handwriting.
Nor does
the absence of a confession.
The
scientific examination remains the same.
81. Case Study: Toxicology
Suppose
the case theory is poisoning.
The
expected toxin is not detected.
The
scientist is asked:
“Can you
report that it may have been present but disappeared?”
Perhaps
scientifically possible under some circumstances—but the answer must depend on evidence,
toxicokinetics, sample condition, analytical sensitivity and the actual
circumstances.
It cannot
simply be used as an explanation for an inconvenient negative result.
The
scientist must distinguish:
scientifically
supported possibilities
from
post-hoc
explanations invented to save a theory.
82. Case Study: Digital
Forensics
Suppose a
computer contains deleted files.
The
investigator believes:
“The
accused deleted the evidence.”
The
forensic examiner recovers files showing a deletion event.
But the
timestamp information is incomplete.
The
scientist should not state:
“The
accused intentionally deleted the files at 11:30 PM.”
unless
the evidence supports those specific conclusions.
Digital
evidence can be particularly tempting to overinterpret because computers
generate large quantities of apparently precise data.
A
timestamp can look authoritative.
But its
meaning still has to be established.
83. The Danger of
“Precision”
A number
with many decimal places can look scientific.
For
example:
0.00003784
But
precision in measurement does not automatically mean certainty in
interpretation.
Similarly,
a computer-generated report can look authoritative.
The
scientist must still understand:
- what the software did,
- what assumptions it used,
- what limitations apply,
- whether the input data were
valid.
Technology
does not eliminate the need for scientific judgment.
84. Artificial Intelligence
and Automated Systems
As
laboratories increasingly use automated interpretation and AI-assisted systems,
the same integrity principle applies.
Never
allow an automated system to become a convenient excuse for unexplained
conclusions.
If a
software system produces:
“Match
probability = X”
the
scientist should understand:
- what data were used,
- whether the software was validated,
- whether the correct version
was used,
- whether parameters were
correct,
- whether the result is
reproducible,
- what limitations apply.
And
importantly:
Never
alter the input data simply to obtain the desired output.
85. The Importance of
Version Control
Software,
databases and electronic reports should ideally have controlled versions.
Otherwise:
“Which
version generated this result?”
may
become impossible to answer.
In a
serious forensic laboratory, traceability should exist not only for physical
evidence but also for:
- software,
- analytical methods,
- templates,
- databases,
- calculations.
86. What Should a Scientist
Do If the Result Is Unexpected?
A useful
five-step approach:
Stop.
Do not
immediately report.
Verify.
Check
sample identity, controls, instrument and calculations.
Repeat where scientifically justified.
Not
endlessly—according to procedure.
Consult.
Use a
colleague or technical reviewer if needed.
Document.
Record
what happened and why the final interpretation was reached.
This is
very different from:
“Keep
testing until we get the expected answer.”
87. The Golden Rule of
Re-examination
A good
rule is:
Repeat an
examination because science requires repetition—not because the first answer is
inconvenient.
That
sentence is worth putting on a laboratory training slide.
88. The Role of the
Laboratory Director in Preventing Fabrication
Directors
should ensure that there is no incentive to fabricate.
For
example:
If the
Director asks:
“Why
didn't you get a positive result?”
that can
create pressure.
A better
question is:
“What did
the examination show?”
If the
Director asks:
“Why is
the report inconclusive?”
the
scientist may feel defensive.
A better
question:
“What
limitation prevented a stronger conclusion?”
That
encourages scientific explanation.
89. The Director Should Ask
for Raw Data
In
important cases, senior review should not consist only of reading the final
report.
Ask:
“Show me
the underlying observations.”
For
example:
- chromatograms,
- electropherograms,
- photographs,
- worksheets,
- instrument output,
- calculations.
This
helps detect whether the conclusion actually follows from the evidence.
90. Don't Sign What You
Haven't Reviewed
This is
especially important for supervisors.
If a
supervisor signs a report without reviewing it, the signature can become
meaningless.
A
signature should mean:
“I have
reviewed the work to the extent required by my role and I accept the
responsibility associated with that review.”
If there
is insufficient time to review:
request
more time,
not:
sign
automatically.
91. Professional
Consequences for Supervisors
Supervisors
should remember that responsibility does not disappear simply because:
“The
junior scientist prepared the report.”
If a
supervisor knowingly approves false work, the responsibility may extend beyond
the original examiner.
Therefore,
senior staff should not think:
“It is
their report, not mine.”
If you
approve it, you have a responsibility for the approval.
92. The Importance of
Training on Ethics Through Scenarios
Ethics
lectures often fail because they say:
“Be
honest.”
Everybody
agrees.
Instead,
training should use difficult scenarios:
“Your
report is due tomorrow, but the examination was not completed. What do you do?”
“The
investigator asks you to omit an unfavorable result. What do you say?”
“Your
senior tells you to strengthen the wording. How do you respond?”
“You
discover a colleague has altered data. What is your next step?”
These
questions prepare scientists for actual situations.
93. A Suggested Laboratory

This kind
of table can be displayed in the laboratory.
94. The “Would I Do This If
My Name Were Public?” Test
Before
altering a record, ask:
“Would I
be comfortable explaining this action in an open disciplinary proceeding or
court?”
If the
answer is:
“No,”
stop.
But there
is an even better test:
“Would I
do the same thing if the case involved someone I personally knew and cared
about?”
Scientific
standards should not change with personal involvement.
95. Another Useful Test:
Reverse the Parties
Suppose
you are tempted to suppress a finding because it helps the accused.
Ask:
“If this
same finding helped the prosecution, would I consider it relevant?”
If yes,
it is probably scientifically relevant regardless of which side it helps.
Likewise,
if a finding supports the prosecution, ask:
“Would I
still consider this sufficiently strong if I were evaluating it for the
defence?”
This is a
powerful way to detect selective reasoning.
96. The Scientist Should
Not Decide Which Side Deserves to Win
This may
be the most important professional boundary.
The
scientist may personally believe:
“The
accused is guilty.”
Or:
“The
accused is probably innocent.”
That
personal belief should not determine the scientific report.
The
report should answer:
What does
the evidence show?
The
justice system will integrate that evidence with everything else.
97. What Happens When
Science Contradicts the Investigation?
This is
sometimes uncomfortable.
The
investigator may have spent months developing a theory.
Then the
laboratory produces evidence inconsistent with it.
The
scientist may feel:
“I am
creating a problem for the investigator.”
No.
The
laboratory has done its job.
If the
scientific evidence contradicts the investigation, that information is
potentially extremely valuable.
It may:
- redirect the investigation,
- identify another suspect,
- eliminate a false theory,
- prevent wrongful
prosecution.
A
laboratory that only confirms investigators' theories is not functioning as a
scientific laboratory.
98. A Strong Laboratory Is
Sometimes the One That Says “No”
A good
forensic laboratory should sometimes say:
“No.”
No, the
evidence does not establish that.
No, the
sample cannot be identified.
No, the
method cannot answer that question.
No, the
result cannot be strengthened.
No, the
examination was not completed.
No, that
finding cannot be omitted.
No, the
raw data cannot be altered.
That does
not make the laboratory unhelpful.
It makes
the laboratory dependable.
99. Legal Consequences: Do
Not Memorize One List of Offences
Because
this lecture is for government forensic scientists, I would caution against
presenting a single universal list of criminal sections.
The exact
consequences depend on:
- the jurisdiction,
- applicable criminal law,
- evidence law,
- government service rules,
- departmental disciplinary
rules,
- professional regulations,
- laboratory policies,
- facts of the case.
In India,
for example, the relevant legal consequences may arise under different
statutory provisions depending on exactly what was done—such as false evidence,
fabrication of records, destruction or concealment of evidence, misconduct in
public service, or other applicable offences.
Therefore,
the laboratory should ensure that scientists know which departmental and
legal authorities govern their own service.
The
principle is more important than memorizing section numbers:
Deliberately
falsifying forensic evidence can move from an internal disciplinary matter into
a criminal matter.
100. Professional
Consequences Can Be Severe Even Without Criminal Conviction
A
scientist may not be criminally prosecuted in every case.
But
deliberate misconduct can still lead to:
- departmental inquiry,
- suspension,
- loss of responsibilities,
- adverse service
consequences,
- dismissal,
- loss of professional
standing,
- removal from expert-witness
responsibilities,
- review of previous cases.
The
absence of criminal prosecution does not make the conduct acceptable.
101. The Laboratory's Reputation
Is a Scientific Asset
Government
laboratories often take decades to build credibility.
Courts
begin to trust their reports.
Investigators
know their methods.
Other
laboratories recognize their expertise.
Scientists
build professional reputations.
One
serious integrity scandal can damage that accumulated trust.
And
rebuilding trust is much harder than building it initially.
Therefore:
Protect
the credibility of the institution as carefully as you protect the individual
case.
102. But Institutional
Reputation Must Never Become a Reason to Hide Misconduct
There is
a danger here.
A
Director might think:
“If we
report this, the laboratory's reputation will suffer.”
That is
precisely when transparency becomes important.
A
laboratory that discovers serious misconduct and deals with it appropriately is
ultimately more credible than one that hides it.
Do not
protect reputation by hiding the truth.
Protect
reputation by demonstrating that the laboratory can detect and correct
problems.
103. What the Public Should
Be Able to Expect
A member
of the public should be able to assume:
If
evidence enters a government forensic laboratory, it will not be changed to
suit a political party, investigator, accused person, victim's family, media
narrative or senior officer.
That is a
reasonable public expectation.
Our
procedures should make that expectation realistic.
104. Five Institutional
Safeguards
If I were
advising a government laboratory on preventing fabrication and suppression, I
would emphasize five safeguards.
1. Traceability
Every
significant scientific action should leave an appropriate record.
2. Independent review
Important
conclusions should be reviewed.
3. Controlled access
Not
everybody should be able to alter data.
4. Clear escalation
Scientists
should know where to go when pressure or misconduct occurs.
5. A culture that rewards accuracy, not merely
positive results
These
safeguards are more effective than simply telling people:
“Be
ethical.”
105. A Short Checklist for
Scientists
Before
finalizing a sensitive case, ask:
Did I actually perform every examination I have
reported?
Are the dates accurate?
Are the sample numbers correct?
Are the original records preserved?
Did any quality-control issue occur?
Did I record it?
Did I repeat anything?
Why did I repeat it?
Did I obtain any contradictory findings?
Have I dealt with them appropriately?
Am I omitting anything because it is scientifically
irrelevant—or because it is inconvenient?
Does my conclusion follow from the evidence?
Would another competent scientist be able to
understand how I reached it?
Am I comfortable defending every statement in
court?
If you
can answer those questions honestly, you have done much to protect the
integrity of the case.
106. What Should a
Scientist Do When Unsure?
One of
the best habits is:
Stop and
ask.
If you
are unsure whether:
- a result should be reported,
- a record can be corrected,
- a file can be deleted,
- a test should be repeated,
- an exhibit can be returned,
- a conclusion is sufficiently
strong,
do not
improvise.
Consult:
- the SOP,
- section head,
- technical manager,
- quality manager,
- laboratory director,
- appropriate
legal/administrative authority.
Asking a
question is not weakness.
It is
quality control.
107. Final Case Discussion:
“Just Change the Report”
Let us
imagine the following conversation.
Senior
Officer:
“The
result is too weak. Change ‘inconclusive’ to ‘consistent with.’”
Scientist:
“What
additional scientific evidence supports that change?”
Senior
Officer:
“The
investigation is clear.”
Scientist:
“I
understand the investigation. My concern is that the laboratory conclusion must
be based on the examination findings.”
Senior
Officer:
“I am
asking you as your superior.”
Scientist:
“I
respect that. Because this is a scientific conclusion, I would prefer to have
the matter reviewed through the technical process before changing the report.”
That is
the kind of response we should teach.
Not:
“You
can't tell me what to do.”
Not:
“I
refuse.”
Not:
“I will
go to the media.”
Just:
“Let's
put the scientific question through the proper process.”
108. Final Message
Let me
end with a distinction that I think every forensic scientist should remember.
An honest mistake says:
“I got it
wrong.”
Scientific negligence says:
“I failed
to take reasonable care.”
Scientific misconduct says:
“I knew
what the evidence was, but I deliberately changed, concealed or misrepresented
it.”
These are
not the same.
Our
response should therefore also be different.
For
honest error:
Correct
it.
For
negligence:
Investigate
it and improve the system.
For
deliberate fabrication or suppression:
Investigate
it fully and apply the appropriate professional and legal consequences.
There
should be no ambiguity about that last principle.
109. Closing Message to
Forensic Scientists
A forensic
scientist may be asked to work quickly.
A
forensic scientist may be asked to handle difficult cases.
A
forensic scientist may be criticized for an inconclusive result.
A
forensic scientist may be pressured by an investigator.
A
forensic scientist may disagree with a superior.
A
forensic scientist may make an honest mistake.
All of
these are part of professional life.
But there
is one boundary that should remain clear:
Do not
create evidence that does not exist.
And
another:
Do not
deliberately hide evidence that materially matters.
If the
evidence is inconvenient, report it.
If the
evidence is incomplete, say so.
If the
result is inconclusive, report it.
If the
investigation is wrong, the laboratory should not make the science fit the
investigation.
If you
make a mistake, acknowledge it and correct it.
If
somebody pressures you to change the scientific record, use the institutional
mechanisms available to you.
And if
misconduct is discovered, the laboratory must respond.
Not
because we want to punish people.
But
because the credibility of forensic science depends on the reliability of
the scientific record.
A
forensic report may be only one document in a large criminal case.
But to
the person whose liberty depends upon it, it may be enormously important.
That is
why the laboratory should be able to say:
“We did
not report what somebody wanted us to report. We reported what the evidence
showed.”
That is
the standard.
And for
fabrication, falsification and deliberate suppression of evidence, there should
be no acceptable compromise.
Yes. For
a lecture to scientists working in Indian Government FSLs, I would add a
separate “Indian Legal and Institutional Context – Lecturer’s Notes”
section to the record. This will make the lecture much more useful than simply
saying “fabrication is punishable.”
Below is
material you can retain as lecturer's background notes, legal references and
discussion points. I have used the laws currently in force—the Bharatiya
Nyaya Sanhita, 2023 (BNS), Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), and
Bharatiya Sakshya Adhiniyam, 2023 (BSA), which came into force on 1 July
2024. (India Code)
LECTURER'S ADDITIONAL NOTES
Zero Tolerance for Fabrication or Suppression of
Evidence
Indian Legal, Professional and Institutional
Context
1. Opening point for the lecturer
A useful
way to introduce the Indian context is:
“A
forensic scientist in a Government laboratory is not merely an employee
producing a report for the investigating officer. The report may become
scientific evidence before a court. Therefore, the accuracy of the laboratory
record has consequences beyond the laboratory.”
This
distinction is important.
The
investigator may have a theory of the case. The prosecutor may have a theory of
the case. The defence may have another theory.
The
forensic scientist should have neither.
The
scientist should have a scientific question:
What does
the material submitted to me establish, and what does it not establish?
That is
the most practical definition of scientific impartiality.
2. The three new criminal
laws: why they matter to forensic scientists
The three
laws relevant to the lecture are:
|
Law |
Relevance to FSL scientist |
|
Bharatiya
Nyaya Sanhita, 2023 (BNS) |
Criminal
consequences for false evidence, fabrication, false certificates, use of
false evidence, etc. |
|
Bharatiya
Nagarik Suraksha Sanhita, 2023 (BNSS) |
Criminal
investigation and procedure; importantly, forensic examination at crime
scenes for specified serious offences |
|
Bharatiya
Sakshya Adhiniyam, 2023 (BSA) |
Legal
treatment of expert opinion, scientific evidence and electronic/digital
evidence |
All three
came into force on 1 July 2024. (India Code)
This is
an important change in terminology for scientists who still routinely refer to
the old IPC, CrPC and Evidence Act sections.
The
lecturer can say:
“The
underlying principles have continuity, but the section numbers have changed.
When preparing a report or giving evidence today, scientists should be familiar
with the current statutory framework rather than relying only on the old
IPC/CrPC/Evidence Act references.”
3. BNS Section 228 –
Fabricating false evidence
This is
probably the single most useful statutory provision for this lecture.
BNS Section
228 deals with “Fabricating false evidence.”
It covers
creating a circumstance, making a false entry in a book/record/electronic
record, or creating a document/electronic record containing a false statement,
with the intention that it may appear in evidence and cause an erroneous
opinion on a material point.
Why is this particularly relevant to FSL work?
Consider
these hypothetical examples:
Example 1 – False analytical record
A
scientist did not perform a particular confirmatory examination.
The case
record nevertheless states:
“Confirmatory
examination conducted – positive.”
That is
not merely poor documentation.
If done
deliberately and intended to form part of the evidentiary record, it can
potentially fall within the concept of fabricating false evidence.
Example 2 – False quality-control entry
A control
failed.
The
scientist deliberately enters:
“Control
satisfactory.”
The
purpose is to allow the case result to appear valid.
Again,
this is much more serious than a clerical mistake.
Example 3 – Electronic record
A
scientist alters an electronic laboratory record or creates a false electronic entry
so that the case file presents an examination as having been performed or a
result as having been obtained when it was not.
Section
228 expressly includes electronic records.
Lecturer's point
Do not
tell scientists:
“If you
manipulate the report, you can be prosecuted.”
That is
too simplistic.
Instead
say:
“The law
does not only look at the final signed report. A false entry in the underlying
record can itself become legally significant if it is deliberately created to
influence the evidentiary process.”
That is a
much more useful message.
4. BNS Section 229 –
Punishment for false evidence
BNS Section
229 provides punishment for intentionally giving false evidence or
fabricating false evidence.
For false
evidence in a judicial proceeding, the punishment can extend to seven years'
imprisonment and fine up to ₹10,000.
For other
cases covered by subsection (2), the punishment can extend to three years'
imprisonment and fine up to ₹5,000. (India Code)
The
important word for the lecturer is:
INTENTIONALLY
This
allows you to make an important distinction:
|
Situation |
Nature |
|
Typographical
error |
Usually
an error |
|
Calculation
mistake discovered and corrected |
Error |
|
Failure
to follow SOP through carelessness |
Possible
negligence |
|
Repeated
careless practice despite warnings |
Potential
misconduct/negligence |
|
Deliberately
entering a result that was never obtained |
Serious
misconduct / potentially criminal |
|
Deliberately
changing an adverse result |
Potential
fabrication/falsification |
|
Deliberately
hiding material evidence to influence proceedings |
Potentially
serious criminal/professional misconduct |
This
distinction is important because zero tolerance for fabrication does not
mean zero tolerance for honest mistakes.
5. BNS Section 233 – Using
evidence known to be false
BNS Section
233 provides that a person who corruptly uses or attempts to use as true or
genuine evidence which he or she knows to be false or fabricated is punished in
the same manner as if the person gave or fabricated false evidence. (India Code)
Why should an FSL Director discuss this?
Because
misconduct may not stop with the person who originally creates the false
record.
For
example:
A senior
officer becomes aware that an analytical record contains a deliberately false
entry and nevertheless directs that the report be issued and relied upon.
That
raises a different question from:
“Who
originally made the entry?”
The
lecturer should emphasise:
“Do not
assume that responsibility ends with the person who physically typed or signed
the false entry.”
The
precise criminal liability in any actual case will depend on facts and
applicable law. But scientifically, the principle is clear: knowingly
passing forward a false scientific record is unacceptable.
6. BNS Section 234 – False
certificate
This
provision has particular relevance to forensic scientists.
BNS Section
234 deals with issuing or signing a false certificate.
It
applies where a person issues or signs a certificate required by law, or
relating to a fact where the certificate is legally admissible in evidence, knowing
or believing it to be false in a material point. It is punishable in the
same manner as giving false evidence. (India Code)
Practical FSL examples
Depending
on the nature of the document:
- falsely certifying that an
examination was conducted;
- certifying a material fact
that the scientist knows is false;
- signing a certificate
containing a knowingly incorrect material statement;
- certifying compliance or
examination that did not occur.
The
lecturer should caution:
“Do not
sign simply because the document has been prepared by somebody else.”
Before
signing:
Read →
verify → understand → sign.
7. BNS Section 201 –
particularly relevant to Government scientists
BNS Section
201 is headed:
“Public
servant framing an incorrect document with intent to cause injury.”
It
applies where a public servant charged with preparing or translating a
document/electronic record prepares it in a manner he or she knows or believes
to be incorrect, with the requisite intention or knowledge of likely injury.
The provision carries imprisonment up to three years, or fine, or both. (India Code)
This
provision should be discussed carefully.
Do not tell the audience:
“Every
wrong FSL report is an offence under Section 201.”
That is
incorrect.
The
statutory elements, including knowledge/belief and intention/likelihood of
causing injury, matter.
The
useful teaching point is:
“For a
Government scientist, deliberately preparing an incorrect official record is
not merely a workplace issue. Depending on the facts and statutory ingredients,
it may have criminal consequences.”
8. BNS Section 232 –
pressure on somebody to give false evidence
This
section is especially relevant to your earlier lecture on pressure and
influence.
BNS Section
232 deals with threatening another person with injury to person, reputation
or property, with intent to cause that person to give false evidence.
The
punishment can extend to seven years, fine, or both. If an innocent
person is convicted and sentenced in specified circumstances as a consequence
of the threat, the provision contains substantially more serious consequences.
(India Code)
Important distinction for the lecture
Not every
request from an investigator or superior is a criminal threat.
There is
a spectrum:
Request →
persuasion → pressure → improper instruction → threat → coercion
The
scientist should recognise the escalation.
The
practical advice is:
“Do not
wait until pressure becomes a criminal threat before protecting yourself. Start
creating an accurate administrative record when the pressure begins to affect
scientific judgment.”
9. What about political
influence?
This
needs particularly careful treatment.
A
forensic scientist should not be told that every telephone call from a politician
or influential person is automatically an offence.
That
would be legally inaccurate.
Instead,
explain the distinction.
Legitimate interaction
A public
representative may legitimately:
- seek information about
laboratory functioning;
- ask about delays at an
institutional level;
- raise public concerns;
- request improvement in
infrastructure;
- seek information through
lawful administrative channels.
Improper interference
The
problem arises when an individual attempts to influence the scientific
conclusion of a particular case.
For
example:
“The case
is important. Make sure the report is favourable.”
or
“Do not
mention that result.”
or
“The
accused is an important person; make the report accordingly.”
That is
completely different from asking:
“Why is
the laboratory taking six months to issue reports?”
The
latter is an administrative question.
The
former is an attempt to interfere with scientific decision-making.
10. Prevention of
Corruption Act, 1988 – Section 7A
There is
another provision worth mentioning in the context of improper influence.
Section 7A
of the Prevention of Corruption Act, 1988 concerns taking an undue
advantage to influence a public servant by corrupt or illegal means or by
exercising personal influence, in order to induce improper or dishonest
performance or forbearance of a public duty.
The
provision provides for imprisonment of not less than three years and up to
seven years, along with fine. (India Code)
Important caution for the lecturer
Do not
tell scientists:
“Any
political pressure is an offence under Section 7A.”
That is
not what the provision says.
Instead:
“Where
influence is accompanied by the statutory ingredients of corrupt or illegal
means and an attempt to induce improper or dishonest performance of public
duty, the Prevention of Corruption Act may become relevant.”
That is a
legally safer formulation.
11. CCS Conduct Rules –
important for Government scientists
For scientists
working under the Central Government, the Central Civil Services (Conduct)
Rules, 1964 are highly relevant.
Rule 3
establishes basic standards including:
- absolute integrity;
- devotion to duty;
- conduct becoming of a
Government servant;
- high ethical standards and
honesty;
- political neutrality;
- merit, fairness and
impartiality;
- accountability and
transparency;
- decisions solely in public
interest;
- declaration and management
of private interests/conflicts.
This is
extremely useful for the lecture because it converts the idea of “scientific
integrity” from a purely scientific concept into a Government-service
obligation.
Particularly useful phrase
The
amended Rule 3 framework requires Government servants to:
“maintain
high ethical standards and honesty”
and
“promote
the principles of merit, fairness and impartiality in the discharge of duties.”
For a
forensic scientist, those words have an obvious practical application.
12. A particularly useful
rule concerning superior's instructions
The CCS
Conduct Rules also contain an important principle concerning official
directions.
The
framework under Rule 3 provides that a Government servant should exercise best judgment
in official duties, subject to lawful directions of the official superior, and
that directions should ordinarily be in writing. (CGE News - 8th Pay Commission)
This
gives the lecturer a very practical response to:
“Sir/Madam,
my superior told me to change the conclusion.”
The
scientist should not immediately start a confrontation.
A
professional response can be:
“I will
be happy to comply with any lawful administrative direction. Since this
concerns the scientific conclusion of a forensic examination, could the
direction please be given in writing so that I can place it on the record and
seek technical review?”
This is
much safer than saying:
“You
cannot tell me what to do.”
The first
response is professional.
The
second can become personal.
13. Disciplinary
consequences under CCS (CCA) Rules
For
Central Government employees, the Central Civil Services (Classification,
Control and Appeal) Rules, 1965 provide the disciplinary framework.
Rule 11
includes penalties ranging from:
Minor penalties
- censure;
- withholding promotion;
- recovery of financial loss
caused by negligence/breach of orders;
- withholding increments.
Major penalties
- reduction in
pay/time-scale/grade/post/service;
- compulsory retirement;
- removal from service;
- dismissal from service.
Therefore,
the lecturer can tell scientists:
“The
consequences of integrity failure do not necessarily begin with a criminal
case. Administrative and disciplinary consequences can arise independently.”
This is
important.
A
scientist can face:
laboratory
action → departmental inquiry → service consequences
and,
depending on the facts,
criminal
proceedings → court proceedings → professional consequences.
These are
not necessarily mutually exclusive.
14. Important
qualification: State FSL employees
This
should definitely be included in the lecturer's record.
Many
forensic scientists work in State FSLs, not Central Government
laboratories.
Therefore:
CCS
Conduct Rules and CCS (CCA) Rules should not automatically be presented as
applicable to every FSL scientist in India.
For State
Government scientists, the relevant:
- State Civil Services Conduct
Rules;
- disciplinary/CCA rules;
- departmental manuals;
- FSL service rules;
- State Government
notifications;
- laboratory SOPs;
- applicable vigilance rules;
must be
checked.
Suggested lecturer statement
“The CCS
Conduct and CCA Rules are directly relevant to Central Government personnel.
State FSL personnel must consult the corresponding State service rules and
departmental procedures. The underlying principles—integrity, impartiality,
accuracy and accountability—are nevertheless common.”
This
avoids a common mistake in lectures.
15. Bharatiya Sakshya
Adhiniyam – Section 39
For a
forensic scientist, BSA Section 39 is fundamental.
It
provides that when a court has to form an opinion on a matter of science, art
or another specialised field, the opinion of a person specially skilled in that
field is a relevant fact.
It also
specifically recognises the opinion of an Examiner of Electronic Evidence under
Section 79A of the Information Technology Act for matters concerning information
stored or transmitted in electronic/digital form. (India Code)
Why this matters
It
explains why the forensic scientist is in court.
The
scientist is not there simply as another witness who happened to see something.
The
scientist is being relied upon because of specialised knowledge.
That
creates a professional responsibility.
A useful
statement:
“The law
gives the forensic scientist a special evidentiary role because the scientist
possesses specialised knowledge. That privilege carries a corresponding
responsibility not to exaggerate, conceal or manufacture.”
16. BSA Sections 40 and 45
– the scientist's reasoning matters
The BSA
also separately identifies:
- Section 40 – Facts bearing
upon opinions of experts
- Section 45 – Grounds of
opinion, when relevant
This is
very useful when teaching scientists how to prepare reports.
The
report should make it possible to understand:
What was
examined → what was observed → what method was used → what result was obtained
→ what reasoning supports the conclusion → what limitations apply.
A
conclusion without an adequate scientific basis becomes vulnerable.
17. Supreme Court: expert
opinion is important, but not infallible
A very
useful recent Supreme Court reference is the 28 March 2025 judgment in
which the Court discussed scientific test reports and expert opinion.
The Court
observed that expert opinion is relevant but not binding on the court;
it must be assessed, particularly where the expert opinion has shortcomings,
ambiguity or inadequacy. (Sci API)
Lecturer's interpretation
This
gives an important message:
“Do not
assume that because you are the Government laboratory expert, the court will
automatically accept every sentence of your report.”
The
scientist must be able to defend:
- methodology;
- observations;
- calculations;
- quality controls;
- limitations;
- interpretation;
- conclusion.
That is
the real meaning of professional competence.
18. Supreme Court example
concerning an FSL report
A
particularly useful Indian example is a 2023 Supreme Court decision
concerning an FSL report from Madhya Pradesh.
The Court
record noted that an FSL report had been forwarded to the police, but the
report was not included in the case diary when the High Court called for it.
The High Court consequently sought explanations from the Superintendent of
Police and the Regional FSL officer. (Sci API)
Why is this useful for the lecture?
It
illustrates something very practical:
Suppression
need not mean that the scientist physically destroys evidence.
A
forensic report can be:
- prepared;
- dispatched;
- received;
- but not properly placed in
the investigative record.
That can
become a serious procedural issue.
The
lecturer can ask:
“If an
FSL report has already been issued and it contains an unfavourable result, is
the laboratory's responsibility finished once the report leaves the
laboratory?”
The
answer should be:
The
laboratory must follow its prescribed procedure for dispatch, records,
acknowledgements and communication. It should not participate in withholding,
altering or informally replacing the scientific record.
19. BNSS Section 176(3):
forensic science is becoming more central to investigation
This is
an important contemporary development.
BNSS Section
176(3) provides that, for offences punishable with seven years or more,
the officer in charge of a police station shall, from the date notified by the
State Government within the statutory transition period, cause a forensic
expert to visit the crime scene to collect forensic evidence and cause
videography of the process.
Where the
State lacks the required forensic facility, the provision permits notification
of use of a facility in another State. (India Code)
Why is this important for integrity?
It means
that the forensic scientist's role is moving further upstream—from simply
examining articles sent to the laboratory to participating in crime-scene
evidence collection.
Therefore:
scene
documentation → collection → packaging → transport → laboratory receipt →
examination → interpretation → reporting
must all
be scientifically defensible.
20. This also creates a new
pressure point
The
lecturer can pose this question:
“If a
forensic expert attends a high-profile crime scene and the investigating
officer says, ‘We already know who did it; please collect evidence supporting
this theory,’ what should the scientist do?”
The
answer:
The scientist should collect evidence according to
scientific protocol.
Not:
“evidence
against the accused.”
Not:
“evidence
supporting the prosecution.”
But:
relevant
forensic evidence.
That
distinction should be repeatedly reinforced.
21. Government data: the
pressure of workload is real
This is
important because the lecture should not sound as though misconduct occurs only
because of bad individuals.
The
Government itself recognises the infrastructure and workload problem.
In a
December 2024 parliamentary answer, the Ministry of Home Affairs stated that
data on State FSL vacancies and pendency were not centrally maintained, but
reported 3,953 pending cases across seven CFSLs as of October 2024. It
also reported 123 vacancies in those seven CFSLs. (Ministry
of Home Affairs)
This
provides a very useful teaching point:
“A
scientist must never solve a workload problem by manufacturing scientific
certainty.”
If there
are 500 pending cases, the solution is:
- prioritisation according to
lawful criteria;
- additional manpower;
- improved workflow;
- validated automation;
- technical review;
- additional laboratories;
- transparent reporting of
limitations;
—not
falsification.
22. The Government is
itself investing in forensic capacity
The
Ministry of Home Affairs states that the National Forensic Infrastructure
Enhancement Scheme (NFIES) was approved in June 2024 with an outlay of
approximately ₹2,254.43 crore, including nine additional NFSU campuses
and seven new CFSLs, with the objective of addressing trained manpower
shortages and reducing pendency. (Ministry of Home Affairs)
This
gives the lecturer an opportunity to make an important institutional point:
“The
answer to pressure created by insufficient capacity is institutional
strengthening—not lowering scientific standards.”
23. MHA's own quality
framework
A
particularly useful Government reference is the MHA response concerning quality
and standardisation.
The
Directorate of Forensic Science Services has issued:
- Quality Manuals for
accreditation of laboratories under NABL/ISO 17025;
- Working Procedure Manuals in
multiple forensic disciplines;
- quality and working
procedure manuals covering areas such as Biology, DNA, Chemistry,
Explosives, Narcotics, Toxicology, Computer Forensics and others;
- guidelines concerning
collection, preservation and transportation of forensic evidence in
sexual-assault cases. (Ministry of Home Affairs)
This is
important because it demonstrates that:
Scientific
integrity is not supposed to depend solely upon the personal character of an
individual scientist.
It should
be supported by a quality system.
24. FSL Delhi – a useful
Indian institutional example
The
Government of NCT of Delhi describes its FSL as operating under ISO/IEC
17025:2017 and having a Quality Management Division responsible for quality
systems, document control, internal audits, management review, corrective
action, risk management, method validation and scientific integrity. (FSL Delhi)
This can
be used as an example of the practical machinery behind integrity.
Lecturer's point
Scientific
integrity is not just:
“I am an
honest person.”
It is
also:
“The
laboratory has a system that makes it difficult to make an error secretly and
easier to detect, correct and learn from errors.”
25. Why raw data and
underlying records matter
A recent
Bombay High Court record provides a particularly useful practical illustration.
In a
matter concerning DNA examination, the requested laboratory documentation
included:
- worksheets/datasheets;
- bench notes;
- case-opening records;
- receipt and dispatch
records;
- chain-of-custody
documentation;
- storage and movement
records;
- equipment logbooks;
- calibration records;
- electropherograms;
- electronic raw data;
- working procedure manuals;
- validation studies;
- quality-control
documentation.
This makes an excellent lecture point:
“A
forensic report is the visible tip of the scientific process. Underneath it is
the documentary trail that allows another person to understand whether the
conclusion is reliable.”
Therefore:
Never
treat bench notes, raw data, instrument files, QC records and chain-of-custody
documentation as disposable paperwork.
They are
part of the scientific history of the case.
26. A very important
distinction: suppression versus non-disclosure
Scientists
sometimes ask:
“Do I
have to put everything I saw into the report?”
The
answer is no.
A report
cannot contain every microscopic observation, every intermediate thought or
every routine laboratory action.
The real
question is:
Was materially relevant information deliberately
withheld?
A useful
three-question test:
- Is it scientifically
relevant?
- Could it affect
interpretation or the conclusion?
- Am I excluding it for a
legitimate scientific/reporting reason, or because it is inconvenient?
If the answer
to Question 3 is:
“Because
it weakens the prosecution case.”
then the
scientist should stop and reconsider.
27. Inconclusive is a
legitimate scientific result
This
deserves special emphasis.
Scientists
sometimes feel pressure to produce:
positive /
negative
because
investigators want a definite answer.
But many
forensic examinations legitimately result in:
Inconclusive
or
No
opinion possible
or
Insufficient
material
or
Not
suitable for examination
These are
not failures.
Suggested lecturer statement
“A
scientifically justified inconclusive result is a successful forensic result.
The failure occurs when a scientist converts an inconclusive result into a
definite conclusion merely because somebody wants a definite answer.”
28. Confirmation bias – an
important scientific basis for the lecture
There is
substantial scientific literature showing that forensic interpretation can be
affected by contextual information.
A 2019
systematic review examined 29 primary research studies and found
evidence supporting the influence of confirmation bias on forensic conclusions.
Among studies involving practitioners/trainees and case-specific information,
suspect or crime-context information was associated with bias in a substantial
proportion of the studies examined. The review recommended limiting unnecessary
contextual information, controlling information flow and, where appropriate,
replication by analysts blinded to previous conclusions. (ScienceDirect)
This is
not specifically an Indian study, but it is directly applicable to Indian
laboratories.
There is
also Indian scholarship specifically addressing cognitive bias in forensic
analysis. A 2021 chapter by Poulomi Bhadra, associated with O.P. Jindal Global
University, discusses cognitive biases in forensic decision-making and their
implications for the credibility of forensic evidence in the Indian context. (Pure)
29. How this connects to
investigator pressure
Consider:
Investigator
says: “The accused confessed.”
Scientist
thinks:
“Then
this fingerprint must belong to him.”
That is
dangerous.
Or:
“The
accused is a habitual offender.”
The
scientist now looks at the questioned document differently.
Or:
“The
victim has clearly identified him.”
The
scientist may unconsciously interpret ambiguous biological or trace evidence
more strongly.
Lecturer's point
“Pressure
does not always arrive as an order. Sometimes it arrives as information.”
This is
an excellent line for the lecture.
The
scientist may not be told:
“Change
your result.”
Instead,
the scientist may simply receive a large amount of contextual information that
pushes interpretation toward one conclusion.
30. A practical Indian FSL
protocol for resisting pressure
Give
scientists a simple six-step method.
STEP 1 – Separate the scientific question
Write
down:
What
exactly am I being asked to determine?
STEP 2 – Identify what information is actually
necessary
Do I need
to know:
- the suspect's criminal
history?
- the political importance of
the case?
- the investigator's theory?
- media reports?
Usually
not.
STEP 3 – Follow the SOP
If the
SOP says:
examine →
control → repeat/confirm → interpret → review
follow
it.
STEP 4 – Record unexpected results
Do not
hide them.
STEP 5 – Seek technical review
Especially
where:
- the result is unusual;
- controls failed;
- there is conflicting
evidence;
- the conclusion has
significant limitations;
- there is pressure to depart
from procedure.
STEP 6 – Escalate improper pressure
Use the
laboratory's administrative/quality/vigilance mechanism.
31. What should a scientist
say to an investigator?
Give them
actual language.
Investigator:
“Can you
make the report stronger?”
Scientist:
“I can
review the report for clarity and accuracy, but the conclusion has to remain
within what the examination supports.”
Investigator:
“Don't
mention the negative result. It will confuse the court.”
Scientist:
“If the
result is scientifically relevant to the interpretation, I cannot simply omit
it. I can explain its significance clearly in the report.”
Investigator:
“The
accused is definitely involved. Please examine the sample again.”
Scientist:
“I can
repeat or conduct additional examination if scientifically justified under the
procedure, but the decision will be based on the analytical requirements, not
on the identity of the suspect.”
Superior:
“Change
the conclusion.”
Scientist:
“If there
is a scientific basis for changing the conclusion, I am willing to review it.
Could we record the scientific basis for the proposed change and have it
technically reviewed?”
These
responses are firm without being confrontational.
32. What should the
Director do?
This is
especially relevant because your lecture is being delivered by a former
Director.
A
Director has two responsibilities.
First:
Protect
the scientist from improper external pressure.
Second:
Protect
the laboratory from scientists who misuse “scientific independence” as an
excuse for poor work.
Therefore:
Scientific
independence does not mean freedom from review.
A
scientist should be free from pressure to produce a predetermined conclusion.
But the
scientist should remain accountable for:
- competency;
- SOP compliance;
- documentation;
- quality control;
- technical review;
- accuracy;
- court testimony.
33. The Director's role
when a scientist makes an honest mistake
This is a
very important cultural point.
Suppose a
scientist discovers:
“I
entered the wrong sample number in the draft report.”
The
Director should not automatically treat this as dishonesty.
The
appropriate response may be:
Identify
→ correct → document → assess impact → prevent recurrence.
But
suppose the scientist discovers:
“I
entered the wrong sample number three months ago and deliberately changed the
original record so nobody would notice.”
That is a
very different matter.
Lecturer's principle
“A
laboratory that punishes every mistake will eventually create scientists who
hide mistakes. A laboratory that ignores deliberate dishonesty will lose its credibility.
Good leadership must distinguish the two.”
This is
one of the strongest messages in the lecture.
34. Professional
consequences can precede criminal consequences
Scientists
often think:
“Unless
the police register a case, nothing serious can happen.”
That is
incorrect.
A
Government employee can potentially face:
- preliminary fact-finding;
- quality investigation;
- withdrawal/correction of
report;
- case review;
- departmental proceedings;
- disciplinary penalties;
- adverse career consequences;
- transfer or removal from
sensitive responsibilities where permitted;
- criminal investigation where
statutory ingredients exist.
For
Central Government personnel, CCS (CCA) Rule 11 provides the formal range of
disciplinary penalties. (Indian Kanoon)
35. A useful concept: “case
impact assessment”
If
deliberate misconduct is discovered, the laboratory should not ask only:
“What
punishment should be given to the scientist?”
It should
also ask:
“Which
cases could have been affected?”
For
example, if an analyst has deliberately falsified records over three years:
Potential review questions
- How many cases did the
analyst handle?
- Which disciplines?
- Which conclusions?
- Were there technical
reviewers?
- Were raw data preserved?
- Were controls recorded?
- Were reports challenged in
court?
- Were convictions or
prosecutions dependent substantially on the result?
- Are re-examinations
possible?
- Is retained material
available?
This is
where a laboratory's quality system becomes essential.

37. Indian Government data
can also be used to explain the workload problem
The MHA
Annual Report 2023–24 reported that CFSL scientists gave 2,003 court
evidences during the period 1 April 2023 to 31 January 2024 and attended 300
important crime scenes during that period. (Ministry of Home Affairs)
This
demonstrates that forensic scientists are not isolated laboratory technicians.
They are
participating throughout the criminal justice process:
crime
scene → laboratory → report → court
Therefore,
their professional credibility matters at every stage.
38. A useful Supreme Court
lesson on Government scientific reports
The
Supreme Court has recognised the evidentiary importance of Government
scientific laboratory reports.
In a 2022
judgment discussing a ballistic FSL report, the Court noted that a report under
the then Section 293 CrPC could be used as evidence when it was the report of a
Government scientific expert on material duly submitted for examination. (Sci API)
Although
the statutory framework has now moved to the BNSS/BSA regime, the underlying
lesson for scientists remains:
A
Government laboratory report can become an important part of the evidentiary
record.
Therefore:
Every
sentence should be capable of being defended scientifically.
39. A particularly useful
court-evidence point under the new BNSS
BNSS Section
336 deals with evidence of public servants, scientific experts and medical
officers in certain cases.
It
provides mechanisms for using their reports and, in specified circumstances,
for examination of a successor officer where the original expert has
transferred, retired, died, cannot be found or cannot reasonably be secured,
subject to the statutory conditions. (India Code)
Practical implication
A
scientist should write the report on the assumption that:
“Someone
may have to understand this report years after I wrote it.”
That
means avoiding:
- unexplained abbreviations;
- undocumented changes;
- unsupported conclusions;
- personal shorthand;
- ambiguous terminology;
- conclusions that depend
entirely on memory.
40. The most important
message for the lecture
I would
suggest ending the legal portion with this:
“The law
does not expect a forensic scientist to be infallible. It does, however, expect
the scientist not to knowingly misrepresent the scientific record.”
And then:
“If we
make an honest mistake, we correct it. If the evidence is inadequate, we say
so. If the result is inconclusive, we report it as inconclusive. If somebody
disagrees with our conclusion, we explain the science. But if somebody asks us
to manufacture, falsify or deliberately suppress evidence, that is no longer a
scientific disagreement—it is an integrity issue.”

One important recommendation for your lecture
Because
this is being delivered by a former Director of a Government FSL, I
would avoid making the legal section sound like a lawyer's lecture. The
strongest approach is to take each legal provision and immediately translate it
into a laboratory situation:
Section →
what it means → FSL example → what the scientist should do.
For
example:
BNS 228 –
Fabricating false evidence
↓
False laboratory record
↓
“Examination performed” when it was not
↓
Correct response: document only work actually performed.
That will
make the legal material much more memorable for practicing forensic scientists.
Note: The statutory provisions and
Government rules cited above should be checked against the latest official text
and the scientist's particular Central/State/departmental service rules before
being used as formal legal advice or as exact wording in an official
departmental training programme. The citations above are to current
Government/official or judicial sources where available.
