The Code of Criminal Procedure, 1973 (CrPC) is the primary legislation in India governing criminal law procedures. It outlines the legal framework for investigation, trial, and prosecution of offenses. Enforced on April 1, 1974, CrPC defines the powers and responsibilities of law enforcement agencies, magistrates, and courts. It covers arrest, bail, evidence collection, and sentencing. The code ensures fair trials, protects individual rights, and maintains law and order. It applies to all Indian citizens except those in Jammu and Kashmir, with specific exceptions for armed forces. Amendments have refined CrPC, adapting it to modern legal challenges and human rights standards.
