Section 76 IPC: Act Done by a Person Bound by Law or by Mistake of Fact

Section 76 of the Indian Penal Code, 1860 formed part of the IPC's General Exceptions. It protected an act done by a person who was legally bound to do it, as well as an act done by a person who, because of a mistake of fact and in good faith, believed that the law bound him to do it.

Pre-BNS legal position: This article explains Section 76 of the Indian Penal Code, 1860 as applicable before the Bharatiya Nyaya Sanhita, 2023 came into force on 1 July 2024. For conduct governed by the earlier IPC regime, the applicable law must be considered with the relevant saving and transitional provisions.

What did Section 76 IPC provide?

The provision created a general exception for two closely related situations. First, it covered a person who was actually bound by law to perform the act. Second, it covered a person who, because of a mistake about facts and acting in good faith, believed that he was bound by law to perform it.

Text of Section 76 of the Indian Penal Code, 1860

76. Act done by a person bound, or by mistake of fact believing himself bound, by law. - Nothing is an offence which is done by a person who is, or who by reason of a mistake of fact and not by reason of a mistake of law in good faith believes himself to be, bound by law to do it.

Essential requirements of Section 76 IPC

Actual legal duty: the act may be protected where the person is in fact bound by law to do it.
Alternatively, mistake of fact: protection may arise where a factual mistake causes the person to believe that he is legally bound to act.
Good faith: the mistaken belief must be held in good faith.
Not a mistake of law: Section 76 expressly excludes a belief arising from a mistake about what the law itself requires.
Belief of legal obligation: in the mistake-of-fact branch, the relevant belief is that the person is bound by law to do the act.

Mistake of fact and mistake of law under Section 76

Situation	Section 76 position
Person is actually bound by law to perform the act.	The act falls within the first limb of Section 76.
Person, in good faith, makes a mistake about facts and consequently believes the law binds him to act.	The second limb of Section 76 may apply.
Person is mistaken about the law itself.	Section 76 expressly does not extend its mistake-based protection to a mistake of law.

Meaning of good faith under the IPC

For the IPC framework, the expression "good faith" must be read with the Code's definition of that expression. The requirement is important because Section 76 does not protect every asserted factual mistake: the statutory text requires the person to believe in good faith that he is bound by law to do the act.

Illustrations to Section 76 IPC

Illustration (a): Soldier acting under a lawful command

A, a soldier, fires on a mob by the order of his superior officer in conformity with the commands of the law. A has committed no offence.

This illustration demonstrates the first branch of Section 76: the person acts because the law binds him to perform the act.

Illustration (b): Court officer arrests the wrong person after due enquiry

A, an officer of a Court of Justice, is ordered by that Court to arrest Y. After due enquiry, A believes Z to be Y and arrests Z. A has committed no offence.

The second illustration demonstrates the mistake-of-fact branch. The officer has a legal duty to execute the court's order but, after due enquiry, makes a factual mistake concerning the identity of the person to be arrested.

Core distinction: Section 76 concerns a person who is, or in good faith because of a factual mistake believes himself to be, bound by law to act. The provision itself expressly distinguishes a mistake of fact from a mistake of law.

Section 76 and Section 79 IPC

Section 76 should be distinguished from Section 79 IPC. Section 76 concerns a person who is bound by law, or by mistake of fact in good faith believes himself bound by law, to do an act. Section 79 concerns a person who is justified by law, or by mistake of fact in good faith believes himself justified by law, in doing an act.

Key takeaway

Under Section 76 IPC, an act was not an offence where the person was legally bound to do it, or where a mistake of fact caused the person, acting in good faith, to believe that the law bound him to do it. The exception did not extend to a belief based merely on a mistake of law.
