A) ABSTRACT / HEADNOTE

The judgment in Rajesh Dhiman v. State of Himachal Pradesh examines the contours of fair investigation, evidentiary standards, and appellate interference in acquittals under the Narcotic Drugs and Psychotropic Substances Act, 1985. The Supreme Court addressed whether an investigation stands vitiated merely because the complainant is also the investigating officer, particularly in prosecutions involving commercial quantities of contraband.

The Court revisited earlier conflicting jurisprudence and relied upon the Constitution Bench ruling in Mukesh Singh v. State (Narcotic Branch of Delhi) to reaffirm that no automatic presumption of bias arises from such dual roles unless actual prejudice or likelihood of bias is demonstrated. The judgment further clarifies the doctrine of reasonable doubt, emphasizing that fanciful or implausible defence theories cannot undermine a consistent prosecution case supported by official witnesses.

The Court also dealt with the evidentiary value of hostile independent witnesses and reiterated that non-examination of such witnesses is not per se fatal. Importantly, the judgment upholds the High Court’s power to reverse an acquittal where the trial court has misapplied legal principles or adopted a perverse appreciation of evidence. The ruling strengthens prosecutorial standards in NDPS cases while balancing the accused’s right to a fair trial, thereby contributing significantly to criminal jurisprudence on narcotics control and appellate review.

B) CASE DETAILS

C) INTRODUCTION AND BACKGROUND OF JUDGEMENT

The judgment arises from a long-standing judicial tension in NDPS prosecutions between strict procedural compliance and pragmatic evaluation of evidence. The NDPS Act imposes severe penalties and reverses certain presumptions, thereby demanding heightened scrutiny of investigative fairness.

Trial courts have often leaned towards acquittal where procedural lapses or absence of independent witnesses appear. In the present case, the trial court adopted such an approach, acquitting the accused primarily on doubts arising from hostile independent testimony and the complainant’s dual role as investigator. The High Court, however, reversed the acquittal, finding the trial court’s reasoning legally flawed.

The Supreme Court was thus required to balance the presumption of innocence with statutory objectives of narcotics control, while clarifying the law on bias, reasonable doubt, and appellate interference. The decision is situated within evolving jurisprudence post-Mukesh Singh, which recalibrated earlier rigid standards that favoured acquittal on technical grounds alone.

D) FACTS OF THE CASE

On 09.01.2002, a police team conducting traffic checking at Shamshar noticed a motorcycle without a number plate. Rajesh Dhiman was seated on the pillion carrying a backpack, while Gulshan Rana drove the vehicle. Upon stopping them, the police attempted to associate local witnesses but failed.

The accused were informed of their right to be searched before a Magistrate or Gazetted Officer and consented to search on the spot. From the backpack, 3 kg 100 gms of charas was recovered, sealed, sampled, and sent for chemical examination. The prosecution examined nine witnesses, including eight police officials and one independent witness, Karam Chand (PW-3), who later turned hostile.

The defence did not lead evidence but suggested that the backpack belonged to an unidentified third person who allegedly fled. The trial court acquitted the accused, citing doubts in investigation and hostile testimony. The High Court reversed the acquittal and convicted the accused under Section 20 NDPS Act, imposing ten years’ rigorous imprisonment.

E) LEGAL ISSUES RAISED

i. Whether investigation is vitiated when the complainant himself acts as the investigating officer?
ii. Whether non-examination or hostility of independent witnesses renders the prosecution case doubtful?
iii. Whether an improbable alternate defence version creates reasonable doubt?
iv. Whether the High Court was justified in reversing an acquittal in appeal?

F) PETITIONER / APPELLANT’S ARGUMENTS

The counsels for the appellants submitted that the dual role of complainant and investigator violated principles of fair investigation. They relied upon earlier precedents including Mohan Lal v. State of Punjab to contend inherent bias. It was argued that the independent witness did not support the seizure and that the defence version of a third person owning the backpack raised reasonable doubt. Non-compliance with Section 50 NDPS Act was also alleged. The appellants contended that the High Court ignored these infirmities while reversing a well-reasoned acquittal.

G) RESPONDENT’S ARGUMENTS

The counsels for the respondent State argued that the Constitution Bench in Mukesh Singh had conclusively settled the issue of dual roles. They emphasized the consistent testimonies of official witnesses and the improbability of the defence theory. The State contended that recovery from a backpack does not attract Section 50 NDPS Act and that the High Court rightly corrected the trial court’s misapplication of law.

H) JUDGEMENT

The Supreme Court dismissed the appeals, affirming the High Court’s conviction. The Court held that no presumption of bias arises merely because the informant investigates the case. It stressed that actual prejudice must be shown. The defence theory of an unknown third person was termed ex-facie fanciful. The Court upheld reliance on official witnesses and clarified that non-examination of independent witnesses is not fatal. The High Court’s reversal of acquittal was found justified due to the trial court’s misinterpretation of burden of proof.

a) RATIO DECIDENDI

The ratio lies in reaffirming that fair investigation does not mean perfect investigation. The Court held that bias must be proved and cannot be presumed. Reasonable doubt must be real and based on credible probabilities, not conjectures. Appellate courts may reverse acquittals where trial courts adopt perverse or legally erroneous reasoning.

b) OBITER DICTA

The Court observed that excessive insistence on independent witnesses may impose unrealistic burdens on prosecution, especially in chance recovery cases. It cautioned against mechanical acquittals in NDPS cases.

c) GUIDELINES

i. Dual role of informant-investigator is permissible absent proven bias.
ii. Reasonable doubt must exclude fanciful defences.
iii. Non-examination of independent witnesses requires cautious scrutiny, not automatic acquittal.
iv. High Courts may reverse acquittals where trial courts misapply legal standards.

I) CONCLUSION & COMMENTS

The judgment strengthens NDPS jurisprudence by discouraging acquittals based solely on technicalities. It harmonizes accused rights with societal interest in curbing narcotics offences. The ruling reinforces doctrinal clarity on reasonable doubt and appellate powers while ensuring that fairness remains fact-centric rather than presumptive.
