Which landmark judgment upheld the constitutional validity of the 99th Constitutional Amendment Act and the National Judicial Appointments Commission (NJAC) Act?

💡 Solution & Explanation

The Supreme Court judgment delivered in the Fourth Judges Case in 2015 struck down the 99th Constitutional Amendment Act and the National Judicial Appointments Commission Act as unconstitutional and violative of the basic structure doctrine. Earlier landmark rulings like the Second Judges Case in 1993 established the collegium system for judicial appointments that the NJAC sought to replace.
