Narcotics conviction fails without proved chain of custody, lawful sampling, and admissible evidence linking each accused to the contraband.

In narcotics prosecutions, conviction depends on a reliable chain of custody, properly proved seizure and sampling, and admissible evidence linking each accused to the contraband. The Court noted serious inconsistencies over the number of samples, their custody, malkhana handling, and transmission to the forensic laboratory, and found no satisfactory compliance with inventory and Magistrate sampling requirements. It also held that accused not present at the spot could not be convicted on police interrogation notes or alleged conspiracy alone, because police confessions are inadmissible and no independent evidence established possession, transport, or participation. The prosecution case was therefore found unreliable and the convictions unsustainable.

Issues: (i) Whether the prosecution proved a reliable chain of custody and link evidence for the seized contraband and samples; (ii) Whether the sampling and seizure procedure, including compliance with the statutory requirements governing inventory and sampling, was duly established; (iii) Whether the conviction of the accused not found at the spot could rest on police interrogation notes and alleged conspiracy.

Issue (i): Whether the prosecution proved a reliable chain of custody and link evidence for the seized contraband and samples

Analysis: The evidence showed major inconsistencies about the number of samples prepared, their custody, and their transmission to the forensic laboratory. The seizure officer stated that one sample was handed to the accused, while another witness claimed that three samples were prepared and forwarded. The record did not satisfactorily explain the safe keeping of the samples from seizure to forensic examination, nor did it establish the custody of the seized property in the police malkhana. The original seized material was also produced in a different form than that described at seizure, without any supporting memorandum or authorisation for repacking.

Conclusion: The chain of custody and link evidence were not proved, rendering the forensic report unsafe to rely upon.

Issue (ii): Whether the sampling and seizure procedure, including compliance with the statutory requirements governing inventory and sampling, was duly established

Analysis: The seizure record itself was deficient, as it did not properly account for the alleged presence of chillies with the contraband or show a separate weighment of the narcotic substance. No proceedings were taken for preparing an inventory or drawing samples before the jurisdictional Magistrate. The sampling narrative was internally inconsistent and the forensic packet description did not match the prosecution version with sufficient certainty. These defects went to the root of the reliability of the seizure and sampling process.

Conclusion: The prosecution failed to establish proper compliance with the statutory sampling procedure, and the seizure evidence could not be acted upon.

Issue (iii): Whether the conviction of the accused not found at the spot could rest on police interrogation notes and alleged conspiracy

Analysis: The accused who were not present at the spot were implicated only on the basis of interrogation notes of other accused. A confession recorded by a police officer is inadmissible, and no independent admissible evidence linked those accused to possession, transport, or any proved conspiracy. In the absence of tangible evidence, the conviction against them could not stand.

Conclusion: The conviction of the accused not found at the scene was unsustainable.

Final Conclusion: The prosecution case was found unreliable on both the seizure evidence and the alleged involvement of the remaining accused, and the convictions could not be sustained in law.

Ratio Decidendi: In prosecutions under the narcotics law, conviction cannot be sustained unless the prosecution proves a reliable chain of custody and admissible evidence linking the accused to the contraband; police confessions and unsupported assumptions cannot substitute for legally proved possession or participation.
