THE STATUTE
Original Text
Section 76: Act done by a person bound, or by mistake of fact believing himself bound, by law. Section 79: Act done by a person justified, or by mistake of fact believing himself justified, by law. Section 80: Accident in doing a lawful act. Section 81: Act likely to cause harm, but done without criminal intent to prevent other harm.
Simplified
Sections 76–81 address the first cluster of General Exceptions — situations where the accused caused harm but no crime was committed because the mental element (mens rea) was absent or overridden by a higher legal duty. Section 76 (act bound by law) protects persons legally required to act — a police officer who fires on lawful orders cannot be prosecuted for assault. Section 79 (act justified by law) protects genuine factual mistakes — a customs officer who mistakenly seizes innocent goods believing them contraband is protected. The critical rule: mistake of FACT excuses; mistake of LAW never does. Section 80 (accident during lawful act) — if a person doing a completely lawful activity with due care causes an unforeseeable harm, no crime is committed. A surgeon who encounters an unforeseeable complication in a standard procedure is protected. Section 81 (necessity) — where harm was caused to prevent greater harm. Breaking down a neighbour's door to rescue a child from a fire is protected necessity.
Legal Evolution
Macaulay codified English common law defences of mistake, accident, and necessity precisely where English law left them vague and judge-made, giving magistrates across India clear rules without requiring knowledge of centuries of English case law.

Chirangi v. State (Madhya Pradesh) (1952)
RELEVANCE
Classic case on mistake of fact — a man killed his son in darkness believing him to be a tiger; acquitted under the mistake of fact exception.
Practical Scenarios
"A soldier firing in a crowd under lawful orders — protected under Section 76."
"A doctor who performs emergency surgery on an unconscious patient without consent — protected under necessity/good faith."
"A person who breaks a neighbour's fence to rescue their dog from a well — protected under Section 81 necessity."
Common Queries
Never. Only mistake of FACT is an excuse under Sections 76 and 79. Every person is conclusively presumed to know the law. A person who commits an act believing it is legal when it is illegal gets no protection.
No. Section 80 requires 'proper care and caution.' A drunk driver was not exercising proper care — the accident exception cannot apply. They face Section 304A instead.
