The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) replaced the Code of Criminal Procedure, 1973 with effect from 1 July 2024 and, in doing so, moved forensic science from the margins of Indian criminal investigation to its centre. Under the old Code, whether a forensic team ever reached a crime scene depended largely on the discretion of the investigating officer and on what resources the district happened to have. The BNSS changes that default. Section 176(3) now requires a forensic expert to visit the scene and collect evidence in offences carrying a sentence of seven years or more, with the entire process to be videographed. Section 105 requires audio-video recording of search and seizure operations, and several other provisions push the investigative process toward greater reliance on scientific method, digital documentation and time-bound procedure. This paper examines these statutory changes, situates them against the older CrPC framework, reviews how courts have responded to the new requirements in the short period since the BNSS came into force, and considers the practical difficulties that stand between the text of the law and its implementation on the ground, particularly the shortage of forensic infrastructure and trained personnel. It concludes that while the BNSS represents a genuine legislative commitment to scientific investigation, its success will depend far more on capacity building than on the statute itself.
