Which Section is applicable to punish complainant for not joining inquiry after submitting complaint before the police

No punishment can be given. The concerned authority can dismiss the case. The 'another person' can file a case against the complainant for whatever losses he may have suffered due to the case. Rarely courts impose a fine for wasting their time, if the case is before a court.

Dear Queriest,

If the complainant fails to appear despite issuing summonses several times, the concerned authority may dismiss the complainant's testimony. You can make a complaint with the police station where the FIR was filed, requesting that the Complainant be prosecuted under Section 182 or 211 of the Indian Penal Code.
