LUG-106 Substantial Law of Crimes-I (The Bharatiya Nyaya Sanhita, 2023 - I), Unit II: General exceptions (ss. 14-44). · LLB · 60 min
Chapter III of the Sanhita (ss. 14-44) lists the circumstances in which an act that fits the definition of an offence is nevertheless not an offence. This lecture covers the first eleven: mistake of fact (ss. 14, 17), judicial acts (ss. 15-16), accident (s. 18), necessity (s. 19), infancy (ss. 20-21), unsoundness of mind (s. 22) and intoxication (ss. 23-24). Each is read with its text, the Sanhita's illustrations, the leading cases (Tolson, Ram Bahadur Thapa, Chirangi, Khora Ghasi, Dudley and Stephens, Hiralal Mallick, M'Naghten, Dahyabhai, Basdev) and the problem questions of the 2025-26 paper on the tree-cutting accident and the good-faith arrest.
Objectives
- Explain the scheme of Chapter III, the burden of proof under s. 108 BSA and the difference between excusable and justifiable acts.
- Apply ss. 14 and 17 (mistake of fact) to a problem, distinguishing mistake of fact from mistake of law and testing good faith.
- Apply s. 18 (accident) to the tree-cutting problem and state its five ingredients.

- State the law of infancy (ss. 20-21), unsoundness of mind (s. 22) and intoxication (ss. 23-24) with the leading cases.
