While Article 39A (a Directive Principle) advocates for free legal aid, it was the Supreme Court's interpretation of Article 21 (Right to Life and Personal Liberty) that elevated it to a fundamental right. In M.H. Hoskot v. State of Maharashtra (1978), Justice Krishna Iyer held that the right to a "fair, just and reasonable" procedure under Article 21 is meaningless without legal representation for the poor. Therefore, free legal aid was recognized as an essential and enforceable part of Article 21. The later case of Hussainara Khatoon strongly reiterated this principle in the context of undertrial prisoners.
