The criminal procedure in Bangladesh is primarily governed by the Code of Criminal Procedure, 1898 (CrPC), which provides a comprehensive framework for the conduct of criminal trials. This colonial-era law, with subsequent amendments, continues to be the backbone of criminal proceedings in the country. The CrPC outlines procedures for investigation, arrest, bail, trial, and appeal in criminal cases. It defines the powers and responsibilities of law enforcement agencies, courts, and other stakeholders in the criminal justice system. Key aspects of criminal procedure include the process of filing a First Information Report (FIR), rules for arrest and detention, provisions for bail, the conduct of trials, and the appeals process. The law also provides safeguards for accused persons, including the right to legal representation and protection against self-incrimination. Recent amendments have aimed to modernize the criminal justice system, including provisions for speedy trials and the use of technology in court proceedings. The CrPC is complemented by other laws such as the Evidence Act, 1872, which governs the admissibility of evidence in criminal trials. The criminal justice system in Bangladesh follows an adversarial model, where the prosecution and defense present their cases before a neutral judge. The burden of proof in criminal cases lies with the prosecution, who must prove the guilt of the accused beyond reasonable doubt. Understanding the intricacies of criminal procedure is crucial for lawyers, law enforcement officers, and anyone involved in the criminal justice system in Bangladesh.
