Thought I'd elaborate a little on this.
For eg:
Wife put false case under DV act 2005.
Allegations:
1. He beat me.
2. He asked me to bring dowry.
3. He is drunkard.
4. He mixed poison in my food and gave to me.
5. He did not give food to me.
6. He kept me locked in a room and never let me speak to my parents or the outer world.
7. He took away my mobile phone.
8. He has extra matrimonial affair.
9. He is a nymphomaniac, beats me with belt while having s*x.
10. He visits brothels, he brings prostitutes to house.
etc etc.
For each allegation made she has to provide concrete evidence, documents, Such as Medical Report from government doctor or CMO, a complaint against you if you have beaten her, asked her to bring dowry blah blah etc.
Without any evidence, documents, the case wont stand, even if the Magistrate orders u/s 23 of the act which is exparte orders, such should be taken to appeal court [sessions court] where such orders will be set aside and finally the Magistrate has to take into consideration both stories, yours and hers and pass on final order. Even there if the Magistrate gives a one-sided order favoring your wife, still you can approach the Honorable Sessions Court and ask them to look into the matter.
IF they find out that all allegations are baseless and do not have any supporting evidence to such allegations made, they will dismiss such DV plea.
And it should be clearly written in such order from Sessions Court that the petitioner has made allegations and was unable to prove them. Then such order will help you get divorce easily.
Further, you can also file prejury case against your wife for filing false cases against you. If the case is well built and put up, she will be imprisoned for a good 5 years for lying under oath!
