The notable K.M. Nanavati vs State of Maharashtra case involved Kawas Manekshaw Nanavati, a Commander in the Indian Navy. Following a specific incident, Nanavati presented himself at a police station and confessed, leading to his arrest. This event drew considerable support from Mumbai's influential Parsi community.
Despite a conviction being upheld by the Supreme Court, Nanavati's life sentence was subsequently commuted to three years by Vijaya Lakshmi Pandit, the then-Governor of Bombay. Approximately one year after his release, Nanavati relocated to Canada with his family.
This widely publicized case has inspired various forms of media. Adaptations include the 2016 film Rustom, featuring Akshay Kumar, as well as earlier films by Gulzar and Sunil Dutt, in which Sunil Dutt portrayed a character inspired by Nanavati. Most recently, the 2019 web series The Verdict also drew inspiration from the Nanavati case.
