General exceptions and the right of private defence occupy BNS sections 14–44. They succeed IPC Chapter IV (sections 76–106), which excluded liability for acts done under mistake, by children, by persons of unsound mind, under specified forms of consent or compulsion, or in defence of body or property.
The architecture is familiar: first a set of complete or partial excuses (when the prosecution’s actus reus is made out but the law refuses to treat the actor as an offender, or reduces responsibility), then the private defence code that permits force within statutory limits. Most BNS sections in this range are renumbered IPC rules. A smaller set adjusts age language, consent drafting or the packaging of defence-of-property rules.
Mistake, accident, necessity and compulsion
Early exceptions cover acts done by a person bound by law or justified by law, acts of a judge, accident in doing a lawful act, and absence of criminal intent where the IPC historically used sections 76–81. Necessity and compulsion remain narrow: the code does not create a general “lesser evil” defence for every hard choice; it preserves the IPC’s limited formulations.
Practitioners should map old IPC section numbers carefully. An argument built on IPC section 79 (act justified by law) or 80 (accident) is still good law in substance if the BNS counterpart is cited, but the number on the page must be the 2023 section.
Infancy, insanity, intoxication and consent
Child liability continues to use age thresholds, with wording that prefers “child” in places where the IPC used a fixed age phrase. Unsoundness of mind tracks the IPC’s cognitive test lineage (inability to know the nature of the act or that it is wrong/contrary to law), not a modern psychiatric code. Intoxication exceptions remain divided between involuntary intoxication and the more limited role of voluntary drunkenness.
Consent-based exceptions (medical procedures, harmless sporting contact, and related themes) are restated. They interact with later sexual-offence chapters: consent that works as a general exception is not a substitute for the consent analysis built into rape and related offences under Chapter V.
Private defence of body and property
Private defence is still a right, not a privilege granted after the fact by prosecutorial grace. The BNS keeps the IPC pattern:
- no right of private defence against acts of a public servant acting in good faith under colour of office, subject to the classic limits;
- no right where there is time to seek public protection;
- force must not be more than necessary;
- special rules when defence extends to causing death (house-breaking by night, assault with intent to gratify unnatural lust, grievous hurt, and the other IPC-historic triggers, as restated).
Defence of property remains more restricted than defence of body. Causing death in defence of property is confined to the statutory list; mere theft of a moveable in the open is not treated like a night house-breaking.
Using this chapter in practice
Exam and trial arguments in this block are doctrine-heavy, not fine-heavy. The BNS did not invent a new private-defence philosophy. What changed for daily work is numbering and a handful of wording clean-ups. When citing a Supreme Court case decided under IPC sections 96–106, translate the section pinpoints before filing under the BNS.
