My father is harrasing my mother

As per the situation you've explained above it depicts that what you're mother is dealing with violence at home, which is termed as Domestic Violence in the words of Law. Domestic Violence is dealt under section 498(A) of Indian Penal Code (IPC) 1860. The law is titled “Husband or relative of husband of a woman subjecting her to cruelty.” The acts (cruel) done by your father are totally unbearable and henceforth should be put to an end, his treatment towards your mother as a slave is totally against the Article 21 of the Indian Constitution. This article gives a person an individual a right to live a life with respect and integrity, due to which,the Apex Court of India has stated Article 21 as a fundamental right. But,before proceeding for judicial help it's essential that one tries to resolve issues himself/herself. Therefore, it's better that you being a grown up man now confront your father about his actions and what could be consequences that he might land up in. This way, you might probably get a solution for your family issues within family members. If the activities still persists, then you can file a complaint under the given sections mentioned above.

Thanks for the reply . As suggested I have tried myself with the help of my family and relatives by putting the issues across to then and there is no use of it. He tells that I'll be in the same way why should I change and who are u to qstn me and who r u to ask me what ever u want u do I'll be in this way itself .. he answers in this way. To comlain about him to file an FIR he is Lil close to the police department because he Lil bit involved in politics in the mandal level so we are suffering a lot on this please advise what to be done... I request some one to atleast guide him or counsil him.
