Under 482 CrPC, even non-compoundable offences can be quashed by High Courts

(2013) 4 SCC 58, Jitendra Raghuvanshi v. Babita Raghuvanshi

 

The High Court in exercise of its inherent powers can quash criminal proceedings or FIR or complaint in appropriate cases in order to meet the ends of justice and Section 320 CrPC does not limit or affect the powers of the High Court under Section 482 CrpC. … Even if the offences are non-compoundable, if they relate to matrimonial disputes and the Court is satisfied that the parties have settled the same amicably and without any pressure it is held that for the purpose of securing ends of justice, Section 320 CrPC would not be a bar to the exercise of power of quashing FIR, complaint or the subsequent criminal proceedings.
