Corresponding IPC
Section 99 IPC

Bare Act text

(1) There is no right of private defence, —

(a) against an act which does not reasonably cause the apprehension of death or of grievous hurt, if done, or attempted to be done, by a public servant acting in good faith under colour of his office, though that act, may not be strictly justifiable by law;

(b) against an act which does not reasonably cause the apprehension of death or of grievous hurt, if done, or attempted to be done, by the direction of a public servant acting in good faith under colour of his office, though that direction may not be strictly justifiable by law;

(c) in cases in which there is time to have recourse to the protection of the public authorities.

(2) The right of private defence in no case extends to the inflicting of more harm than it is necessary to inflict for the purpose of defence.

Explanation 1.—A person is not deprived of the right of private defence against an act done, or attempted to be done, by a public servant, as such, unless he knows or has reason to believe, that the person doing the act is such public servant.

Explanation 2.—A person is not deprived of the right of private defence against an act done, or attempted to be done, by the direction of a public servant, unless he knows, or has reason to believe, that the person doing the act is acting by such direction, or unless such person states the authority under which he acts, or if he has authority in writing, unless he produces such authority, if demanded.

Text as enacted in the Bharatiya Nyaya Sanhita, 2023 (Act No. 45 of 2023), in force from 1 July 2024. Source: India Code, Government of India.

In simple words

There is no private defence against good-faith acts of public servants (or those directed by them) that do not reasonably cause apprehension of death or grievous hurt, or where there is time to seek public authorities' protection. The right never extends to more harm than necessary. Explanations require knowledge or reason to believe the actor is, or acts for, a public servant.
