Section 99 Acts against which there is no right of private defence

There is no right of private defence 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.

There is no right of private defence 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.

There is no right of private defence in cases in which there is time to have recourse to protection of the public authorities.

Extent to which the right may be exercised.—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.

Old law or new?

Which one applies to a case

The BNS repealed the IPC from 1 July 2024 (section 358(1)). The repeal does not reach back: under section 358(2), penalties and punishments incurred for offences committed against the IPC still stand, and proceedings for them may be started, continued and enforced as if the IPC had not been repealed. An act done before 1 July 2024 is therefore dealt with under the IPC section; an act done on or after that date, under the BNS.
