Article 124(1) and the Supreme Court (Number of Judges) Act, 1956

Article 124(1) of the Constitution provides for a Supreme Court consisting of the Chief Justice of India and, "until Parliament by law prescribes a larger number," not more than seven other judges. This makes the actual sanctioned strength a matter of ordinary legislation — the Supreme Court (Number of Judges) Act, 1956 — rather than a constitutional amendment, so Parliament can revise it by simple majority.
