A case under 295-A for insulting Hinduism (or any other religion for that matter) can only be registered upon complaint made by the Central Government, or the Provincial Government concerned, or some officer empowered in this behalf by either of the two Governments, not upon direct complaint made by any Pakistani Hindu citizen.
(Section 196 of the Pakistan Code of Criminal Procedure prohibits courts from taking cognizance of certain offences unless complaint is made by the government. It empowers the government alone to become complainant and prosecute cases registered under section 295-A)
A case under all other clauses of section 295 (offenses related to insulting Islam) can be registered upon complaint made by any Pakistani Muslim citizen.
I believe that Pakistan Code of Criminal Procedure should be amended and (as in case of 295-A) only the Central or concerned Provincial governments should have the authority to make complaints about offenses related to all religions, including Islam. This will greatly reduce the misuse and abuse of Blasphemy Laws in Pakistan.
