NDPS convictions require reliable Section 67 statements and proven chain of custody before guilt can be sustained.

A conviction under the NDPS Act should not rest solely on statements recorded under Section 67 where voluntariness is doubtful, the statements are retracted, or material inconsistencies undermine reliability. Such statements are treated as weak evidence and require independent corroboration from dependable material. The text also emphasises that the prosecution must prove the chain of custody and the link between the seized parcel, the tested sample, and the accused beyond reasonable doubt; gaps in documentary proof, an unverified courier trail, missing call records, and sample-weight discrepancies will defeat that burden. The stated ratio is that both corroboration and reliable link evidence are necessary before sustaining conviction.

Issues: (i) Whether the conviction could be sustained on the basis of statements recorded under Section 67 of the Narcotic Drugs and Psychotropic Substances Act, 1985, and whether those statements were voluntary and adequately corroborated; (ii) Whether the prosecution had proved the chain of custody and the link between the seized parcel, the sample tested, and the accused beyond reasonable doubt.

Issue (i): Whether the conviction could be sustained on the basis of statements recorded under Section 67 of the Narcotic Drugs and Psychotropic Substances Act, 1985, and whether those statements were voluntary and adequately corroborated.

Analysis: The prosecution case rested primarily on statements attributed to the accused and to two other witnesses said to support the alleged courier trail. The record showed serious doubts about voluntariness, including custody at the time of recording, retraction, and material inconsistencies between the successive statements. A confession or inculpatory statement recorded in such circumstances is only a weak piece of evidence and cannot safely form the sole basis of conviction unless independently corroborated by reliable material.

Conclusion: The statements were not safely capable of sustaining the conviction, and the alleged corroboration was insufficient.

Issue (ii): Whether the prosecution had proved the chain of custody and the link between the seized parcel, the sample tested, and the accused beyond reasonable doubt.

Analysis: The evidence disclosed gaps in investigation, absence of meaningful documentary proof, failure to verify the alleged courier chain, and no reliable call records or other hard evidence connecting the accused with the parcel. There was also a material discrepancy between the sample weight drawn at seizure and the sample received by the laboratory, which further weakened the prosecution case. In these circumstances, the link evidence was not established to the requisite standard.

Conclusion: The prosecution failed to prove the alleged link evidence and the sample trail beyond reasonable doubt.

Final Conclusion: The conviction and sentence could not be sustained, and the appellants were entitled to acquittal.

Ratio Decidendi: A conviction under the Narcotic Drugs and Psychotropic Substances Act, 1985 cannot rest solely on uncorroborated or doubtful statements recorded under Section 67 when the surrounding evidence does not reliably establish the chain of custody, the link evidence, or the identity of the accused in the alleged trafficking transaction.
