Section 197 Cr.P.C provides protection to certain public servants, including police officers, from being prosecuted for offenses committed while acting in their official capacity. It mandates that prior sanction from the government is necessary before such individuals can be prosecuted, ensuring they are not unduly harassed and can perform their duties without fear.
"Acting or Purporting to Act in Discharge of Official Duty"
This phrase signifies that the actions of the public servant must be connected to their official responsibilities. It's not limited to actions strictly within prescribed duties but also includes those that reasonably fall under their role, even if they exceed what is strictly necessary.
Cognizance
Cognizance refers to the authority of a court to take notice of a matter and proceed with legal action. In this case, the court evaluated whether taking cognizance of the offenses against the petitioner without prior sanction was lawful.
