The Supreme Court of India has three jurisdictions under the Constitution: original, appellate, and advisory. The Supreme Court serves as a Constitutional Court as well as a Court of Appeal. The Court sits in benches of varying sizes, as determined by the Registry on the directions of the Chief Justice of India (CJI), who is the Master of the Roster.
Constitution Benches of the Supreme Court typically comprise five, seven, or nine judges who deliberate on a specific issue related to constitutional law. Article 145(3) of the Constitution provides for the setting up of a Constitution Bench. It says a minimum of five judges need to sit for deciding a case involving a “substantial question of law as to the interpretation of the Constitution”, or for hearing any reference under Article 143, which deals with the power of the President to consult the Court.
Typically, cases before the Supreme Court are heard by Division Benches (of two judges) or full Benches (three judges) to examine a wide range of topics, such as film prohibitions/restrictions or charges that a police commissioner abused his position. Under its very broad jurisdiction, the Supreme Court has entertained frivolous public interest litigations, such as demands that passages be deleted from the Quran or secularism be removed from the Preamble to the Constitution.
