Section 329 BNSS in Simple Words

The report must be upon a matter or thing duly submitted to the expert for examination or analysis and report in the course of a proceeding under the Sanhita.

Example of Section 329 BNSS

During a trial under the Bharatiya Nagarik Suraksha Sanhita, 2023, a seized sample is duly submitted to Vikram, a scientific expert certified, by notification, by the State Government for this purpose under Section 329(4)(g) BNSS, for examination and report. Under Section 329(1) BNSS, the report under the hand of Vikram may be used as evidence in the trial. Later, the Court thinks fit to summon Vikram under Section 329(2) BNSS to examine Vikram as to the subject-matter of the report, and has not expressly directed Vikram to appear personally. Vikram is unable to attend personally, so Section 329(3) BNSS allows Vikram to depute Ananya, a responsible officer working with Vikram who is conversant with the facts of the case and can satisfactorily depose in Court on behalf of Vikram.
