The Supreme Court has held that an order directing police investigation under Section 156(3) CrPC is a pre-cognizance step, and therefore prior sanction under Section 197 CrPC for prosecuting a public servant is not required at that stage. Sanction becomes relevant only when a court takes cognizance of an offence. The ruling clarifies that magistrates need not await prosecutorial sanction before directing an investigation into alleged offences committed by government officials.

This ruling resolves a critical procedural question about when the protection of Section 197 CrPC (now Section 218 BNSS) is triggered for public servants. Section 197 CrPC mandates prior government sanction before a court can take cognizance of an offence allegedly committed by a judge, magistrate, or public servant while discharging official duties. The question was: does this sanction requirement apply even at the S.156(3) stage?

The Supreme Court answered no. S.156(3) empowers a magistrate to direct the police to register an FIR and investigate a complaint — but this is a pre-cognizance power. The magistrate is not taking cognizance of the offence at this stage; cognizance comes later when the magistrate applies judicial mind to the evidence or charge-sheet. Since sanction under S.197 is a condition precedent only to taking cognizance, it cannot be demanded at the investigation-direction stage.

This distinction matters enormously in practice: requiring sanction at the S.156(3) stage would effectively give government authorities a veto over whether police even investigate complaints against their officials. The ruling ensures that the investigative machinery can be set in motion without the government first clearing the accused. The protection under S.197 is preserved — it simply operates at the right procedural moment: cognizance, not investigation. Students must map the chronological sequence: complaint → S.156(3) order → investigation → charge-sheet → cognizance → S.197 sanction check.
