RAM LAL NARANG ETC. ETC. vs STATE OF DELHI (ADMN.)

The Supreme Court examined the scope of Section 173 of the Criminal Procedure Code, 1973, regarding the police's power to further investigate after a magistrate has taken cognizance of an offence. The Court held that the police retain the authority to conduct further investigations even post cognizance, as long as it is within the ambit of the law. The judgment clarified that such investigations can lead to the filing of a supplementary charge sheet, thereby reinforcing the procedural rights of the police in criminal investigations.
