Text of Section 171 BNSS
171. Prevention of injury to public property.
A police officer may of his own authority interpose to prevent any injury attempted to be committed in his view to any public property, movable or immovable, or the removal or injury of any public landmark, buoy or other mark used for navigation.
Meaning and scope of Section 171
Section 171 appears in Chapter XII of the BNSS, which deals with preventive action of the police. Its purpose is preventive rather than punitive. It allows a police officer to act immediately to stop an attempted injury to public property that the officer personally sees.
1. "A police officer may of his own authority interpose"
The expression means that the police officer need not first obtain a separate judicial order merely to step in and prevent the injury described by the section. The power is tied to immediate prevention and must be exercised lawfully and for the protective purpose stated in the provision.
2. "In his view"
The text links this specific preventive power to an attempted injury occurring in the officer's view. The section is therefore framed for an immediate situation witnessed by the police officer.
3. Public property: movable or immovable
The section expressly covers both movable and immovable public property. In practical terms, movable public assets may include items capable of being moved, while immovable public property may include public buildings, structures, land or fixtures. Section 171 itself does not set out a separate definition of "public property".
4. Public landmarks and navigation marks
The protection also extends to the removal or injury of any public landmark, buoy or other mark used for navigation. This makes the section applicable not only to conventional public property but also to public markers that serve boundary, identification or navigational functions.
Does Section 171 create an offence or punishment?
No. Section 171 is a procedural and preventive provision. It authorizes police intervention to prevent damage, but it does not itself specify a punishment. If the conduct also amounts to an offence under the Bharatiya Nyaya Sanhita, 2023 or another applicable law, criminal liability must be determined under the relevant substantive provision.
Important: Section 171 should not be read as a standalone penal section. Its function is to empower preventive action by the police in the circumstances described in the text.
