- The Code of Criminal Procedure, 1973, deals primarily with the procedure for investigation, inquiry, and trial of offences. - Preventive detention is governed by specific laws like the National Security Act, COFEPOSA, etc., enacted under the powers provided by the Constitution (Article 22). These laws have their own procedures for detention, review, and limited rights of the detenu. - The provisions for bail in the CrPC (Sections 436-439) apply to persons accused of having committed offences, allowing for their release during the pendency of investigation, inquiry, or trial, often upon furnishing security. These provisions do not apply to persons detained under preventive detention laws, which operate outside the normal criminal process based on suspicion of future acts.
