NDPS proof requires a secure chain of custody and reliable seizure evidence before conviction can stand.

In NDPS prosecutions, conviction depends on reliable proof that the seized substance was duly recovered, safely preserved, and conclusively linked to the sample examined by the forensic laboratory. Where independent seizure witnesses turn hostile, the seized narcotic is not produced before the trial court, and custody of the samples shows an unexplained break, the evidentiary link between recovery and forensic report is fatally weakened. The stated principle is that such deficiencies may justify benefit of doubt because the prosecution must establish seizure and identity of the material through cogent and trustworthy evidence.

Issues: Whether the conviction under the Narcotic Drugs and Psychotropic Substances Act, 1985 could be sustained when the independent seizure witnesses turned hostile, the custody of the seized samples remained unexplained for a material period, and the seized contraband was not produced before the trial court.

Analysis: The prosecution case rested substantially on police testimony after the independent witnesses to seizure did not support the recovery. The Court found that the samples sent for forensic examination had an unexplained break in custody between seizure and deposit in the laboratory, and that the seized narcotic itself was not produced before the trial court. In such circumstances, there was no reliable evidence connecting the forensic report with the substance allegedly recovered from the accused. The Court applied the same principle previously affirmed in similar NDPS matters, namely that the prosecution must prove seizure and identity of the material with cogent and trustworthy evidence, and that non-production of the seized substance, coupled with doubtful custody and hostile panch witnesses, creates a fatal deficiency in proof.

Conclusion: The conviction could not be sustained. The appellant was entitled to the benefit of doubt and was acquitted of the charges.

Final Conclusion: The prosecution failed to establish the link between the alleged recovery and the forensic report with the degree of certainty required in an NDPS case, so the conviction and sentence were set aside.

Ratio Decidendi: In prosecutions under the NDPS Act, conviction cannot be sustained unless the prosecution proves by reliable evidence that the seized substance was duly recovered, safely preserved, and conclusively linked to the sample examined by the forensic laboratory; unexplained breaks in custody and non-production of the seized material may entitle the accused to benefit of doubt.
