Case Note & Summary
The case involved an appeal by the State against the acquittal of the accused, Rajangam, by the High Court of Madras. The background of the case stemmed from an incident where the accused was arrested for possessing contraband opium based on information received by police officers. The arrest was made by P.W.4, who informed his superior, P.W.5, leading to the accused's apprehension and subsequent investigation. The accused was convicted and sentenced to 10 years of rigorous imprisonment by the Special District and Sessions Judge, Madurai. However, during the appeal, it was argued that the same officer who registered the crime also conducted the investigation, which was deemed improper. The High Court agreed with this argument and acquitted the accused, prompting the State to appeal to the Supreme Court. The Supreme Court considered whether the investigation was valid given the dual role of the officer involved. Citing the precedent set in Megna Singh v. State of Haryana, the court noted that an officer who arrests should not investigate to ensure impartiality. The court found no error in the High Court's ruling and dismissed the appeal, affirming the acquittal. The decision underscored the importance of maintaining the integrity of criminal investigations.
