To be fair, the majority of men are pretty barbaric and do physically abuse women after marriage. They totally deserve a law like that. I have heard so many stories of brides getting physically and emotionally abused by their in-laws and husband that I pretty much consider it a part of our culture.
Yes and I am putting forward a use of the law to deter offenders who happen to exist in large numbers. Domestic Violence is a serious problem in India and a law like this does help.
