Brief Facts - My friend's wife committed suicide 5 years ago. His father-in-law did not raise any suspicion for the first few months and the Post Mortem report etc clearly stated that the deceased died due to suicide by hanging. After a few months, my friend's father in law changed his stance and pushed the authorities to convert the death into a dowry death and homicide. Subsequently, another Post Mortem was conducted and again the cause of death was established as Suicide by Hanging.
However, my friend's father in law refuses to accept the sad fact. Five years have passed by and there has been no charge-sheet so far !! To shape public opinion, he has been religiously tapping the Television media, Newspapers and set up internet blogs saying that my friend committed homicide. Shockingly, he states that my friend committed homicide because he has a homos*xual relationship with me, and wanted to get rid of his wife !!! This is in the newspapers and Television in Tamilnadu while the suicide occured in Mumbai. My friend's father-in-law resides in Tamilnadu.
I wish to file a Defamation case against my friend's father-in-law. Can I file in Mumbai or should I do it in Tamil Nadu ? Can the defamation case be a Criminal case ?
