India's judiciary structure and how judges are actually appointed through the judge-led Collegium system.
The Supreme Court (Art 124-147) has original, appellate, and advisory jurisdiction, and is the final interpreter of the Constitution; High Courts (Art 214-231) are the highest courts within each state, with writ jurisdiction under Art 226 β wider than the Supreme Court's under Art 32, since HCs can issue writs for 'any other purpose' too, not just Fundamental Rights.
Judicial appointments are made through the Collegium system β a judge-led body (the Chief Justice of India plus senior-most SC judges for SC appointments) that recommends names to the government, evolved through the 'Three Judges Cases' (1981, 1993, 1998) reinterpreting 'consultation' under Art 124 and 217 as effectively requiring 'concurrence.' The government's attempt to replace it with the National Judicial Appointments Commission (NJAC) was struck down by the Supreme Court in 2015 as violating the Basic Structure (judicial independence).
APPSC tests the origin of the Collegium through the Three Judges Cases, and the NJAC's 2015 strike-down β this connects to Judicial Review, Activism & PIL, already covered on this site.
