🔄 Appointment & Removal

AspectDetail
ConventionSenior-most judge of the Supreme Court is appointed CJI — this is a convention, not a constitutional mandate
ProcessOutgoing CJI recommends successor (senior-most judge) in writing → Ministry of Law processes → President issues warrant of appointment
OathCJI takes oath before the President (Article 124(6))
Retirement ageSC judges (including CJI) retire at 65 years of age — fixed by Article 124(2); not removable before this except by impeachment
RemovalBy impeachment under Article 124(4) — requires address of both Houses in the same session with special majority; Judges (Inquiry) Act, 1968 governs procedure; no CJI has ever been impeached
Supersession controversy (1973)PM Indira Gandhi bypassed three senior judges (Justices Shelat, Grover, Hegde) to appoint A.N. Ray as CJI. A political controversy; convention of seniority restored post-1977

🏛️ Collegium System — Three Judges Cases

CaseYearRuling
First Judges Case — S.P. Gupta v. Union of India1981"Consultation" in Article 124(2) does NOT mean "concurrence" — executive had primacy; government could disagree with CJI's recommendation
Second Judges Case — SCAORA v. Union of India19939-judge bench overruled S.P. Gupta. Devised the Collegium System: CJI + 2 senior-most SC judges must recommend; CJI's opinion is binding on the executive
Third Judges Case — Presidential Reference19989-judge bench (advisory opinion): expanded Collegium to CJI + 4 senior-most SC judges. If 2 of 4 collegium members disagree, CJI should not recommend; if collegium reiterates, government bound to accept
NJAC Strike-down — SCAORA v. Union of India20155-judge bench (4:1) struck down 99th Constitutional Amendment (2014) that created NJAC (Article 124A). Held: NJAC violated judicial independence — a basic structure doctrine element. Collegium system restored

Current position (April 2026): Collegium system (CJI + 4 senior SC judges) remains in force. For HC judges: CJI + 2 senior-most SC judges.

A.N. Ray (14)ADM Jabalpur v. Shivkant Shukla (Habeas Corpus case)1976During Emergency, majority ruled Article 21 (Right to Life) stands suspended; Courts cannot review detention. Justice H.R. Khanna alone dissented — celebrated as a beacon of judicial independence; Khanna was later superseded for CJI
M.H. Beg (15)Maneka Gandhi v. Union of India19787-judge bench (delivered 25 Jan 1978, last day before Chandrachud became CJI); expanded Article 21 — any law depriving personal liberty must be fair, just, and reasonable; golden triangle of Articles 14, 19, 21

🛡️ NHRC Chairperson — Eligibility & Change

AspectDetail
Original provision (1993)Protection of Human Rights Act, 1993: NHRC Chairperson must be a retired CJI specifically
After 2019 AmendmentProtection of Human Rights (Amendment) Act, 2019: Eligibility broadened — Chairperson may now be a retired CJI OR retired SC judge (not necessarily CJI)
Exam trapMany questions use the old (pre-2019) provision. Correct post-2019: "retired CJI or retired SC judge"
Current Chairperson (Apr 2026)Justice V. Ramasubramanian — retired SC judge (not a former CJI); assumed charge 23 December 2024; appointed under the amended provision

⚠️ Exam Traps & High-Yield Points

#Trap / Common MistakeCorrect Fact
1Maneka Gandhi judgment was delivered under CJI Y.V. ChandrachudDelivered 25 Jan 1978 — presiding CJI was M.H. Beg (CJI 15). Chandrachud became CJI on 22 Feb 1978 — after the judgment
2Shah Bano judgment was NOT by CJI ChandrachudWrong — CJI Y.V. Chandrachud personally wrote the Shah Bano judgment (1985). Correctly attributed to him
3Collegium = CJI + 2 judges (for SC appointments)Post Third Judges Case (1998): Collegium for SC appointments = CJI + 4 senior-most SC judges. CJI + 2 applies to HC appointments
4First Judges Case (1981) established collegiumFirst Judges Case gave executive primacy (consultation ≠ concurrence). Collegium established by Second Judges Case (1993)
5India has had a woman CJIAs of April 2026, India has had no woman CJI. Justice B.V. Nagarathna is expected to become the first in Sept 2027
6K.N. Singh held the shortest CJI tenure at 17 daysCorrect — K.N. Singh (CJI 22) served only 17 days; J.C. Shah (36 days) and S. Rajendra Babu (30 days) are close but longer
7NHRC Chairperson must be a retired CJIPost 2019 amendment: retired CJI or retired SC judge. Current chair (V. Ramasubramanian) is a retired SC judge, not a former CJI
8Mohammad Hidayatullah was President of IndiaHe was Acting President (20 Jul – 24 Aug 1969, when V.V. Giri resigned to contest elections), NOT President. He also served as Vice-President (1979–84)
9Y.V. and D.Y. Chandrachud are the same personThey are father and son — both became CJI; first such pair in Indian history
10ADM Jabalpur — all judges ruled against civil libertiesJustice H.R. Khanna alone dissented, holding Right to Life cannot be suspended during Emergency. He was later superseded for CJI as punishment for the dissent
11Ranjan Gogoi was the first CJI to become an MPCorrect — first retired CJI nominated to Rajya Sabha (March 2020). This is constitutional but was widely criticised as undermining judicial independence
12Appointment of CJI is constitutionally mandated to follow senioritySeniority is a convention, not a constitutional mandate. It was violated in 1973 when Indira Gandhi superseded three senior judges to appoint A.N. Ray
13SC judges can be removed by a simple majorityRemoval requires special majority in each House in the same session: (a) majority of total membership + (b) two-thirds of members present and voting. No SC judge has ever been impeached
