What is the procedure to punish this culprit?

Disposition would depend upon the strength of ADMISSABLE evidence (whether mitigating or aggravating). Further, the way the law is written, although the TN Govt. Servants’ Conduct Rules, 1973 requires a written declaration from the involved parties that Dowry didn’t play any part in the ritual, there seems to be no preclusion against its demand in future, i.e., during the course of marriage. Therefore, this particular statute would lose punitive relevance (IF a post-marriage violation was proved to have had occurred). The only REAL EVIDENCE I would deliberate upon (and verify) is receipts and testimony from credible sources. You have indicated that “Mrs. Widow Kumari (aka 498A lady) filed false dowry complaint against her husband's family”. I take this to mean that the complaint was determined to be frivolous. But, regardless, by filing such a complaint, hasn’t Mrs. Kumary also implicated her father in the crime? Also, unless Mrs. Kumari was to produce damaging evidence to support her accusation, I daresay her “complaint” should be viewed no more seriously than fictitious hearsay; an ambitious attempt to ‘put the squeeze’ on her husband’s family (with the connivance of the Bandits in Uniform): Desi entrepreneurship at its putrid best! Shame! Shame! Under such circumstances, I would surmise the best way to punish THESE culprits would be to overbid the other party and motivate our mercenaries in uniform to shift loyalties.  Good Luck! Have Fun!
