Martin D'Souza safeguard
The procedural protection from Martin D'Souza v. Mohd. Ishfaq (2009) 3 SCC 1 requiring that before registering a criminal case against a doctor under IPC § 304A (now BNS § 106), the investigating officer must obtain a prima facie opinion from a competent medical authority or medical board. Failure to do so renders the registration an abuse of process.
