Definition
A bench of minimum five judges of the Supreme Court constituted under Article 145(3) to decide cases involving substantial questions of law as to the interpretation of the Constitution, or references made by the President under Article 143.
The Constitution Bench is the Supreme Court at its most authoritative — the minimum five-judge bench required for constitutional interpretation. Article 145(3) mandates: 'The minimum number of Judges who are to sit for the purpose of deciding any case involving a substantial question of law as to the interpretation of this Constitution or for the purpose of hearing any reference under article 143 shall be five.' Decisions of the Constitution Bench create binding precedents under Article 141 — binding on all courts in India and on all smaller Supreme Court benches. A two-judge or three-judge bench of the Supreme Court cannot overrule a Constitution Bench decision; only another Constitution Bench can.

Full Legal Analysis
Constitutional Bench: The Supreme Court at Its Most Authoritative
The Constitution Bench is where India’s most important constitutional questions are definitively resolved. From Kesavananda Bharati (1973) to Puttaswamy (2017), from Navtej Singh Johar (2018) to Sabarimala (2018) — the great constitutional cases that have shaped Indian jurisprudence have all been decided by Constitution Benches. These decisions bind every court in India and can only be overruled by another Constitution Bench.
Article 145(3): The Five-Judge Minimum
The constitutional requirement is minimum five judges — larger benches (7, 9, 11, and even 13 judges in Kesavananda Bharati) are constituted when the complexity and importance of the case warrants. Notably: (a) 7-judge bench: Typically for referring issues to a 9-judge bench or overruling a 5-judge bench. (b) 9-judge bench: For overruling 7-judge bench decisions or resolving major constitutional disagreements. (c) 11-judge bench: Extremely rare — the T.M.A. Pai Foundation (2002) educational rights case was decided by an 11-judge bench. (d) 13-judge bench: The Kesavananda Bharati case (1973) was the largest Constitution Bench ever — deciding the fundamental question of whether Parliament can amend any part of the Constitution.
What Constitutes a 'Substantial Constitutional Question'
Not every constitutional question requires a Constitution Bench. The question must be 'substantial' — genuinely requiring constitutional interpretation for its resolution. A case involving the application of an already-interpreted constitutional provision to a specific set of facts does not require a Constitution Bench. Courts have held that 'substantial' means: (a) the point has not been decided before; (b) the decision involves a significant question of constitutional law; or (c) conflicting decisions by smaller benches need resolution. A two-judge bench that encounters such a question must refer it to a Constitution Bench — it cannot decide it itself.
“The Constitution Bench is the Court at its most serious — five or more minds committed to the hardest constitutional questions. Its decisions are the most authoritative statements of constitutional law available in India. They bind all courts, all governments, all citizens — for generations, until another Constitution Bench says otherwise.”
