Clarification on section 498a of ipc

i need a clarification on 498A misuse by Brides for compelling the Husband and their relative so there is any remedy available for the innocents..???

Please give the answer in respect of the Below mention case

Abbriviations of the case

Bride: Mrs. W

Husband: Mr. H

Relative : R

Mrs. W (who lives in a village) married with Mr. H (who is also from the neighbor village)and after the 15 or 20 days the wife said that she will not live in the village she want to marry with the Nephew of the Mr. H who is a CA upon the refusal she left the house of husband and go to his father house.

and after two years Mrs. W said that she want all the gifts back which are given during the marriage and the compensation and Mr. H was read to pay the same. but the Bride filed a  FIR on husband and his 17 other relatives under 498A. and out of the 17 relatives 9 are those who are not even met with the Mrs. W.

but the case was not in the court yet.

so my question is that whether any safeguard is available to the Mr. H and other innocent relatives????? 

and what is the relative in this Act? should we take the help of General clauses Act for the deifnition of Relatives ??
