Legal Commentary & Landmark Judgments: Section 329

Section 329 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (corresponding to Section 293 of the CrPC, 1973) governs the admissibility of reports of designated Government scientific experts (CFSL, FSL, Serologists, Ballistic Experts, Chemical Examiners) without requiring them to depose in person.

  • Designated Scientific Experts: Covers Chemical Examiners, Chief Inspector of Explosives, Directors of Fingerprint Bureaus, Central Forensic Science Laboratory (CFSL) Directors, Serologists, and other notified experts.
  • Substantive Admissibility: Any document purporting to be a report under the hand of such expert upon any matter or thing duly submitted to them for examination or analysis may be used as evidence.
  • Right to Cross-examine: The Court may, and shall on application by the accused or prosecution, summon and examine the expert as to the subject-matter of the report.
Key Landmark Precedents:
  • State of H.P. v. Mast Ram, (2004) 8 SCC 660: The Supreme Court confirmed that the report of a government scientific expert is admissible per se under Section 293 CrPC (Section 329 BNSS), but if the report is cryptic or challenged, the expert must be summoned.
  • Murari Lal v. State of M.P., (1980) 1 SCC 704: Held that handwriting and ballistic expert opinions must disclose the scientific reasons and comparative data on which the conclusion is based.
Courtroom Practice & Strategic Litigation Guidance:

Never accept a cryptic FSL or ballistic report at face value. Move an application under Section 329(2) demanding the appearance of the Ballistic/DNA expert to cross-examine on chain-of-custody, sample contamination, and probability ratios.
