Industrialist Nusli N Wadia has filed a criminal defamation case against Tata Sons, its interim chairman Ratan Tata and some directors for alleged "defamatory and offending" contents in a special resolution moved to seek his removal from three Tata Group firms.

Wadia, who has been accused of siding with ousted Tata Group chairman Cyrus P Mistry, filed the defamation suit in the court of additional chief metropolitan magistrate here.
