A magistrate's court in Mumbai has denied permission to subject dismissed Railway Protection Force (RPF) constable Chetansinh Chaudhary, accused of shooting four people on a moving train, to narco tests. The court's reasoning is based on the principle that an accused person's right to remain silent is a fundamental right and cannot be violated.

The court's order, issued on August 11, emphasizes that an accused cannot be forced to undergo narco tests, brain mapping, or polygraph tests solely for the purpose of "smooth investigation." The Government Railway Police (GRP) had requested permission from the Borivali magistrate court to conduct these tests on Chaudhary.
