A significant share of NDPS trials at the Asansol court turns on procedure rather than dispute over possession itself. The Drugs and Cosmetics or NDPS sampling rules require that representative samples be drawn, sealed in the accused's presence, and sent to an authorised laboratory promptly. Gaps in this chain frequently surface during cross-examination and can raise doubts about the purity and identity of what was seized.
Section 52A of the NDPS Act permits the preparation of a physical description, photographs, and samples in the presence of witnesses at the time of seizure, which obviates the need to produce the entire bulk at trial. Where officers fail to follow this procedure or where the sample size, sealing, or laboratory analysis report is inconsistent, the defence can legitimately challenge the evidentiary value of the entire recovery.
Raising these points is not a technical trick but a substantive safeguard. The sample tested at the laboratory must be shown to be the same material seized from the accused. A careful review of the seizure memo, the inventory, the forwarding letter, and the analyst's report often exposes discrepancies. A lawyer familiar with such files will ask for certified copies well before the trial date, not at the last hearing.
