The “Law of FIR, Arrest, Bail, Investigation & Trial” comprehensively covers the Indian criminal justice process, from the initial registration of a First Information Report (FIR) to the final trial. This area of law is crucial for understanding how law enforcement handles criminal cases, including the procedures for arrest, bail, investigations, and trials. Recent legal reforms, particularly the Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023, have updated these procedures, and this book focuses on the practical application of these changes.
