STATE BY INSPECTOR OF POLICE(TAMIL NADU) vs RAJANGAM

The Supreme Court held that the investigation of a case by the same officer who registered the crime is impermissible, as established in Megna Singh v. State of Haryana (1996) 11 SCC 709. The Court found that P.W.6, who registered the FIR, also conducted the investigation, violating the principle of an independent investigation. Consequently, the Court upheld the High Court's acquittal of the accused due to this procedural irregularity, emphasizing the necessity for an independent officer to conduct the investigation under Section 57 of the Narcotic Drugs and Psychotropic Substances Act, 1985.
