Hello,

The police officers destroyed the public record in 2015.

It came to light in the year 2024, that they had not even maintained a record in their dairy.

The victim wants to sue the police officers under sec-9 of public record acts, and 120b,166,166A,201,204 r/w 34 of IPC 

1. The Code of Criminal Procedure (CrPC) is not retrospective. 
   no penal law can have a retrospective effect.
2. 20(1) of the Indian constitution imposes a limitation on the law-making power of the constitution. It prohibits the legislature from making retrospective criminal laws

but the issue is now which law will be applicable? 
 complaint under 200 r/w 190 crpc 
or complaint under 223 r/w 210 Crpc.??
and what about the abovementioned penal section?
