This document presents a landmark judgement on Article 14 of the Indian Constitution, specifically the case of Chiranjit Lal Chowdhury v. Union of India. It clarifies that a single person can form a class and that the onus is on the challenger to prove unreasonableness in legislation. The judgement discusses the principles of reasonable classification, the permissible limits of state power in enacting laws, and the criteria courts use to assess discrimination and arbitrariness. This is essential reading for legal practitioners, students, and anyone interested in constitutional law and equality rights in India.
