The enactment of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) marks a transformative shift in the administration of criminal justice in India, repealing and replacing the Code of Criminal Procedure, 1973. Among its most critical facets is the procedural codification governing the deprivation of personal liberty via arrest. While maintaining the constitutional balance under Article 21, the BNSS incorporates structural mechanisms, electronic governance, and explicit duties upon the arresting officer to prevent arbitrary detention. This paper critically examines the statutory framework of arrest under Chapter V of the BNSS, with particular emphasis on Sections 35, 36, 37, 47, and 53. It evaluates the mandatory duties imposed upon arresting personnel, including identification protocol, intimation of grounds, preparation of the arrest memo, designated police control room recordation, and medical examination safeguards. Through doctrinal analysis and comparative statutory evaluation, this paper demonstrates how digital compliance mechanisms and explicit supervisory safeguards under the BNSS institutionalise the principles laid down in landmark judicial rulings such as D.K. Basu v. State of West Bengal and Arnesh Kumar v. State of Bihar. Finally, the paper assesses practical challenges in grassroots compliance and proposes recommendations for institutional capacity building.
