Doctrine of Reasonable classification under Article 14 of the Constitution of India refers to a lawful and justifiable categorisation of individuals or groups based on intelligible differentia that distinguishes them from others. This classification must have a rational nexus to the legislative objective it seeks to achieve.

It allows for tailored treatment, acknowledges diverse circumstances and is instrumental in addressing social inequalities without violating fundamental rights. The doctrine ensures fairness and prevents arbitrary discrimination, permitting the legislature to enact laws that cater to specific needs while upholding the constitutional principles of equality and justice. Judicial scrutiny ensures that classifications are reasonable, non-arbitrary and serve a legitimate purpose
