Minerva Mills v. Union of India
AIR 1980 SC 1789 · 5-judge bench
The 42nd Amendment (1976) tried to give constitutional amendments complete immunity from judicial review and gave Directive Principles priority over Fundamental Rights whenever they conflicted. This was challenged.
The Court struck down both changes, holding that limited government power itself — including judicial review of amendments — is part of the basic structure, and that the balance between Fundamental Rights and Directive Principles is itself a basic feature that can't be tilted entirely one way.
Confirmed and applied Kesavananda Bharati's basic structure doctrine to actually strike down a specific amendment — proving it wasn't just theoretical, and cementing judicial review as untouchable even by Parliament's amending power.
