Chapter 12: Preventive Action of the Police - Summary


The preventive powers and duties are laid down in Chapter 12 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS 2023) titled “Preventive Action of the Police”. It contains Sections 168 to 172 which together define the scope, authority and procedural safeguards for preventive police action. This Chapter is the statutory successor of "Chapter XI-Preventive Action of the Police" under the Code of Criminal Procedure, 1973 (CrPC), amended to conform to the revised legislative framework.

It is the primary responsibility of the State to maintain public law and order, which is very essential for the peace, harmony and overall socio-economic progress of the society. As per division of legislative authority as per the Union List , State List and 'Concurrent List' of the 'Seventh Schedule' of the Constitution of India , this duty is primarily under the Police Department under the Home Department of the State Government concerned, and the Central Government as well, when required .

India is a democracy and, as such, affords its citizens “fundamental rights” and other legal protections. These rights are, however, not absolute and are subject to reasonable limitations in the interest of 'Public Order', 'Security' and prevention of crimes. To this end the Police are vested with certain statutory powers to be exercised in good faith for taking preventive action in respect of any contemplated unlawful act or possible offence. These powers are intended to prevent the occurrence of offences and to ensure public safety and the protection of property.
