Step 1: Meaning of Article 14.
Article 14 ensures two key principles: Equality before the law (a British concept) and Equal protection of the laws (an American concept). These prevent arbitrary actions by the State.
Step 2: Judicial interpretation.
The Supreme Court has expanded Article 14 to include the rule of non-arbitrariness. Any State action must be fair, just, and reasonable.
Step 3: Conclusion.
Thus, Article 14 is the foundation of equality rights in India.
