BNS 2023 — General Exceptions Sections 14–44: Complete Notes for Judiciary Exam 2027
The Bharatiya Nyaya Sanhita (BNS) 2023 replaced the Indian Penal Code (IPC) 1860 effective July 1, 2024. The chapter on General Exceptions (Chapter III, Sections 14–44) is one of the most important and frequently tested areas in all Judiciary exam (PCS-J) papers. Understanding when an act is NOT an offence under BNS — due to age, insanity, consent, necessity, mistake of fact, or private defence — is essential for every judiciary aspirant preparing for 2026–27 exams.
What Are General Exceptions?
General exceptions are circumstances under which an act that would ordinarily constitute an offence is excused or justified by law. When a general exception applies, the act does not attract criminal liability — either because the accused lacked the requisite mental element (mens rea) or because the act was justified in the circumstances.
Key principle: The burden of proving a general exception lies on the ACCUSED (Section 105 of Indian Evidence Act / BSA 2023). However, the prosecution must establish the offence beyond reasonable doubt first.

Key Exceptions Analysed in Detail
1. Insanity Defence — Section 22 BNS (M’Naghten Rules)
Section 22 BNS corresponds to Section 84 IPC. A person is not criminally liable if, at the time of the act, they were:
- Suffering from unsoundness of mind, AND
- Did not know the nature of the act, OR
- Did not know that the act was wrong or contrary to law
Important: The test is at the TIME of the act, not before or after. Medical insanity ≠ legal insanity (M’Naghten Rules).
Leading Cases:
- Sudhakaran v. State of Kerala (2010): SC clarified that irresistible impulse alone ≠ unsoundness of mind under IPC S.84/BNS S.22
- Hari Singh Gond v. State of MP (2008): Mere abnormality does not amount to legal insanity
2. Right of Private Defence — Sections 17–33 BNS
The right of private defence is one of the most tested areas in PCS-J Mains. Key principles:
- Right extends to body AND property (both self and others)
- The right is NOT available against police/public servant doing their duty lawfully
- The right to cause death is available only in specific circumstances (Section 18(2) BNS): assault causing reasonable apprehension of death/grievous hurt, rape, kidnapping, wrongful confinement
- The right must be exercised proportionately — no more harm than necessary
3. Minority Defence — Sections 20–21 BNS
The age-based defence:
- Below 7 years: Absolute immunity — cannot commit any offence (Section 20 BNS = S.82 IPC)
- 7–12 years: Conditional immunity — exempt only if the child had not attained sufficient maturity of understanding to judge the nature and consequences of the act (Section 21 BNS = S.83 IPC)
4. Necessity — Section 19 BNS (S.81 IPC)
An act done with good faith to avoid greater harm is excused, provided:
- There was no reasonable alternative
- The harm avoided was clearly greater than the harm caused
- The person did not bring about the necessitous situation themselves
5. Consent as Defence — Sections 25–27 BNS
- Section 25: Consent of person above 18 — act not intended to cause death and not likely to cause death; consent valid if person knows the risk
- Section 26: Consent to risk harm for person’s own benefit (good faith acts by doctors)
- Section 27: Consent by guardian for minor or insane person in good faith
