The Kesavananda Bharati Case (1973) is one of the most important constitutional judgments in India. 
 Main outcome: 
 - The Supreme Court introduced the Basic Structure Doctrine, which says that while Parliament can amend the Constitution, it cannot change its “basic structure.” 
 Basic structure includes: 
 - Rule of law, 
 - Separation of powers, 
 - Fundamental rights, 
 - Judicial review, etc. 
 So, the Court gained the power to strike down any constitutional amendment that violates the basic structure.
