The provision allows specified scientific reports to be used as evidence in criminal proceedings without requiring the concerned Government scientific expert to appear personally before the Court in every case. At the same time, the Court retains the power to summon and examine the expert where necessary.
The provision is particularly relevant to criminal cases involving forensic, chemical, biological, medical, technical or other scientific examination.
Meaning of Reports of Government Scientific Experts
A Government scientific expert is a person holding an officially recognised scientific or technical position whose examination or analysis may assist a criminal court in determining facts relevant to a case.
Section 329 permits reports prepared by specified Government scientific experts to be used as evidence in an inquiry, trial or other proceeding under the BNSS.
The provision is intended to simplify the presentation of scientific evidence while preserving judicial control over the examination of the expert.
Statutory Basis
The relevant provision is:
Section 329, BNSS, 2023 – Reports of certain Government scientific experts
The section recognises reports prepared by specified Government scientific experts and provides for their use in criminal proceedings.
The provision also gives the Court power to summon and examine the expert where the Court considers such examination necessary.
Government Scientific Experts Covered
Section 329 applies to reports prepared by the specified categories of Government scientific experts, including experts working in recognised Government scientific institutions and laboratories.
The provision covers reports from specialised scientific authorities dealing with matters such as:
- forensic examination;
- chemical analysis;
- scientific investigation;
- biological examination;
- technical examination; and
- other specialised scientific matters falling within the statutory categories.
The specific statutory categories should be distinguished from private experts whose evidence is governed by the general law relating to expert evidence.
Essential Elements
1. Report Must Be Prepared by a Specified Government Scientific Expert
The special procedure applies only to reports prepared by the Government scientific experts covered by Section 329.
A report prepared by an individual outside the specified statutory categories does not automatically receive the benefit of this provision.
2. Report Must Concern Scientific or Technical Examination
The report must arise from the scientific or technical functions of the concerned Government expert.
It may contain the findings of examination, analysis or scientific investigation conducted in the course of official duties.
3. Report May Be Used as Evidence
A qualifying report may be used as evidence in an inquiry, trial or other proceeding under the BNSS.
The personal attendance of the scientific expert is therefore not automatically necessary in every case.
4. Court May Require Personal Examination
The Court may summon the Government scientific expert and examine the expert concerning the subject matter of the report when it considers such examination necessary.
This ensures that the statutory convenience does not prevent judicial examination of scientific evidence where clarification is required.
Procedure
The operation of Section 329 can be understood as follows:
- Scientific material or an article relevant to a criminal investigation is submitted for examination.
- The examination is conducted by a Government scientific expert falling within the statutory categories.
- The expert prepares a report containing the scientific findings.
- The report is placed before the Court.
- The report may be used as evidence in accordance with Section 329.
- The expert need not automatically appear before the Court.
- Where necessary, the Court may summon the expert and examine the expert concerning the report.
- The Court evaluates the scientific report along with the other evidence in the case.
Powers of the Court
The Court has the power to summon the Government scientific expert for examination concerning the subject matter of the report.
This power is important where:
- the findings require clarification;
- there is an apparent inconsistency in the report;
- the methodology requires examination;
- the parties raise a material objection;
- the Court considers oral examination necessary for a fair determination of the case.
The provision therefore facilitates scientific evidence without removing judicial scrutiny.
Nature of Scientific Reports
A scientific report is generally based upon examination, analysis or testing conducted by a person possessing specialised scientific knowledge.
The report may assist the Court in determining technical facts that cannot ordinarily be established through ordinary witness testimony.
However, the scientific expert does not decide the guilt or innocence of the accused. The expert provides scientific findings, while the Court determines their legal significance after considering the entire evidence.
Important Distinctions
Government Scientific Expert and Private Expert
Section 329 concerns specified Government scientific experts.
Evidence from a private expert is not automatically brought within the special statutory mechanism merely because the person possesses scientific qualifications. The applicable provisions governing expert evidence must be considered separately.
Scientific Report and Oral Evidence
Section 329 facilitates the use of the scientific report without requiring the expert to appear in every case.
However, the Court retains the power to summon the expert for examination when necessary.
Scientific Evidence and Final Decision
A scientific report assists the Court in understanding technical or scientific facts.
The report itself does not determine the guilt or innocence of the accused. The final determination remains with the Court.
Relationship with Forensic Evidence
Section 329 is particularly relevant to modern criminal investigations involving forensic science.
Scientific examination may be required in matters involving:
- questioned documents;
- chemical substances;
- biological material;
- fingerprints;
- forensic samples;
- toxicological analysis;
- other scientific or technical material.
The report provides the scientific findings obtained from the examination.
The evidentiary treatment of such findings must also be considered with the applicable provisions of the Bharatiya Sakshya Adhiniyam, 2023.
BNSS and CrPC
Section 329 of the BNSS corresponds to Section 293 of the Code of Criminal Procedure, 1973.
The provision substantially continues the earlier CrPC framework concerning reports of certain Government scientific experts.
The principal change is the incorporation of the provision into the BNSS and its corresponding renumbering.
The underlying objective remains the same: to facilitate the use of reports prepared by recognised Government scientific experts without requiring their personal attendance in every proceeding.
Relationship with BSA
The BNSS provides the procedural framework for criminal proceedings, while the Bharatiya Sakshya Adhiniyam, 2023 governs the law of evidence.
Section 329 specifically facilitates the use of reports of certain Government scientific experts. The general rules governing expert evidence, relevance and evaluation of evidence continue to operate alongside this provision.
Therefore, Section 329 should not be understood as making every scientific report automatically conclusive or determinative.
Example
Suppose a substance seized during a criminal investigation is sent to a recognised Government scientific laboratory for analysis.
A Government scientific expert examines the substance and prepares a report identifying its chemical characteristics.
The report may be used in the criminal proceeding in accordance with Section 329 without necessarily requiring the scientific expert to appear personally before the Court.
If the Court considers the expert’s examination necessary, it may summon the expert and examine the expert regarding the report.
Common Confusions
Is a Government scientific expert required to appear in every criminal trial?
No.
Section 329 facilitates the use of qualifying scientific reports without requiring the expert’s personal attendance in every case.
Can the Court examine the scientific expert personally?
Yes.
The Court may summon and examine the expert concerning the subject matter of the report where it considers such examination necessary.
Does the scientific report conclusively establish the guilt of the accused?
No.
A scientific report provides technical or scientific findings. The Court must assess those findings together with the other evidence before reaching its conclusion.
Does Section 329 apply to every scientific expert?
No.
The provision applies to the specified categories of Government scientific experts contemplated by the section.
