Strict compliance with NDPS search authority requirements: unauthorised search and investigation could not sustain the conviction.

Section 42 of the NDPS Act was applied strictly: only the specified officers, or officers specially authorised by government notification, could lawfully enter, search, seize and arrest without warrant. The record showed that the head constable who first searched the bag, and the Station House Officer, were not duly authorised on the relevant date, so the search and recovery lacked lawful competence. The Court also noted that the alleged recovery was not satisfactorily corroborated by the hostile motbirs and that the prosecution rested on an investigation initiated without authority. The conviction was therefore set aside and the appeal succeeded.

Issues: Whether the search, seizure, arrest and investigation in an offence under the Narcotic Drugs and Psychotropic Substances Act, 1985 were vitiated because they were conducted by officers who were not authorised under Section 42 of the Act.

Analysis: Section 42 empowers only the specified categories of officers, or those specially authorised by Government notification, to enter, search, seize and arrest without warrant in cases under Chapter IV of the Act. The record showed that at the time of the occurrence the relevant police notifications had not yet authorised the head constable who first searched the bag, and the Station House Officer also had no authority on that date under the applicable notification regime. The evidence further showed that the alleged recovery was not satisfactorily corroborated by the hostile motbirs, and the prosecution foundation rested on an investigation initiated and carried forward without lawful competence. In a statute carrying a severe minimum punishment, the Court held that the authorising provision must be strictly complied with and that the accused was entitled to a fair investigation by a competent officer.

Conclusion: The investigation and search were unauthorised, the conviction could not stand, and the appeal succeeded in favour of the appellant.
