Fair investigation in NDPS cases: same officer as complainant and investigator, plus unexplained non-production of witnesses, can defeat the prosecution.

In NDPS prosecutions, a fair investigation must also appear fair, so the same person should not act as complainant, seizing officer and investigator because that combination creates a real apprehension of bias and can vitiate the case. The document also notes that while public witnesses are not invariably mandatory, once the prosecution relies on named independent witnesses to search and seizure, their non-production must be satisfactorily explained; if the cited witnesses are not traceable or the explanation is not accepted, an adverse inference may follow and the prosecution may fail.

Issues: (i) Whether the NDPS prosecution was vitiated because the complainant and investigating officer were the same person. (ii) Whether failure to produce the cited public witnesses to the search and seizure was fatal to the prosecution case.

Issue (i): Whether the NDPS prosecution was vitiated because the complainant and investigating officer were the same person.

Analysis: In prosecutions under the NDPS Act, where a reverse burden of proof operates, the investigation must be fair and must also appear to be fair. A person who made the allegations, or conducted the search and seizure, should not also the case, because such a combination creates a real apprehension of bias and undermines the constitutional guarantee of fair trial. The Court applied this principle to the present case and rejected the attempt to distinguish between complainant, informant, and seizing officer.

Conclusion: The prosecution stood vitiated on this ground, and the finding was in favour of the appellant.

Issue (ii): Whether failure to produce the cited public witnesses to the search and seizure was fatal to the prosecution case.

Analysis: Although public witnesses are not always mandatory in NDPS cases, once the prosecution asserts that named independent witnesses participated in the raid and signed the documents, their non-production must be satisfactorily explained. Where the stated addresses are found to be false or the witnesses are not traceable, the omission casts serious doubt on the prosecution version and may justify an adverse inference. On the facts, the explanation offered was not accepted.

Conclusion: The non-examination of the cited public witnesses undermined the prosecution and supported acquittal of the appellant.

Final Conclusion: The appeal succeeded, the conviction and sentence were set aside, and the appellant was acquitted of the NDPS charge.

Ratio Decidendi: In NDPS cases, where fair investigation is essential because of the reverse burden of proof, the informant, complainant, or seizing officer should not also be the investigator, and if the prosecution claims association of named independent witnesses, failure to produce them without a satisfactory explanation can be fatal to the case.
