Article 131 (Original Jurisdiction of the Supreme Court)

Article 131 of the Constitution of India confers upon the Supreme Court an exclusive and original jurisdiction to adjudicate disputes within the federal polity. The provision appears in Part V, Chapter IV of the Constitution, which establishes the Union Judiciary, and it became operative on 26 January 1950. Its drafting reflected the federal architecture the Constituent Assembly sought to entrench: a single apex tribunal empowered to resolve constitutional conflicts arising from the division of legislative and executive power between the Centre and the constituent units. The provision is modelled in part on the federal-dispute clauses of the Government of India Act, 1935 (Sections 204 and 207), and on comparative practice in federal constitutions such as that of the United States and Australia, where the highest court arbitrates questions touching the federal compact itself rather than the private grievances of individuals.

The text restricts Article 131 to three configurations of parties: disputes between the Government of India and one or more States; disputes between the Government of India and one or more States on one side and one or more other States on the other; and disputes between two or more States. The jurisdiction is original, meaning a matter commences directly in the Supreme Court without prior adjudication by any subordinate forum, and it is exclusive, meaning no other court may entertain such a dispute. The crucial threshold is substantive: the dispute must "involve any question (whether of law or fact) on which the existence or extent of a legal right depends." A claimant State or the Union must therefore plead the infringement or jurisdictional contest of a justiciable legal entitlement, not a mere political grievance or administrative friction. Proceedings are instituted by a suit, governed by Order XXVI of the Supreme Court Rules, 2013, and the Court sits as a court of first instance to receive pleadings, frame issues, and record evidence.

A significant qualifying clause—the proviso to Article 131—excludes from this jurisdiction any dispute arising out of a treaty, agreement, covenant, engagement, sanad, or similar instrument entered into before the commencement of the Constitution and continuing in operation, or which provides that the said jurisdiction shall not extend to such a dispute. This carved out the legacy of pre-Independence instruments executed with the princely states. Article 131 must further be read alongside Article 262, which empowers Parliament to bar both the Supreme Court and all other courts from adjudicating inter-State river-water disputes; the Inter-State River Water Disputes Act, 1956 exercises that power, channelling such conflicts to dedicated tribunals and ousting Article 131 for water-sharing claims.

Article 131 jurisprudence has been shaped by several landmark suits. In State of West Bengal v. Union of India (1963) the Court entertained a challenge by the State to Parliament's power to acquire State-owned coal-bearing land, affirming that a genuine legal-rights question between Union and State falls squarely within the Article. In State of Karnataka v. Union of India (1977) the Court examined the maintainability of a suit concerning a Commission of Inquiry into a Chief Minister's conduct. More recently, States have invoked Article 131 against central legislation: Chhattisgarh challenged aspects of the National Investigation Agency Act, and in 2020 Kerala filed an Article 131 suit against the Citizenship (Amendment) Act, 2019, raising the still-contested question of whether the constitutionality of a central statute may itself be litigated under this head.

Article 131 must be distinguished from adjacent jurisdictional heads. It is not the writ jurisdiction of Article 32, under which individuals seek enforcement of fundamental rights against the State; Article 131 is confined to federal units as parties and to legal-right disputes within the federation. It differs from the appellate jurisdiction under Articles 132 to 134 and the discretionary special-leave power under Article 136, both of which presuppose a prior decision of a High Court or tribunal. It is also distinct from the advisory jurisdiction under Article 143, where the President seeks a non-binding opinion on a question of law or fact of public importance.

A persistent controversy concerns whether a State may use an Article 131 suit to test the vires of a parliamentary statute. A two-judge bench in State of Madhya Pradesh v. Union of India (2011) held that the constitutional validity of central law could not ordinarily be challenged under Article 131, while a later bench in State of Jharkhand v. State of Bihar (2015) doubted that view and referred the question to a larger bench, where it remains substantially unresolved. The frequency of Article 131 suits has risen with sharpened Centre-State political contestation, making the provision a live instrument of cooperative—and adversarial—federalism rather than a dormant clause.

For the working practitioner, Article 131 is the constitutional channel through which the federal balance is judicially policed. Desk officers advising State governments must assess whether a grievance discloses a justiciable legal right and whether Article 262 or the proviso ousts the forum before recommending a suit. Diplomats and policy analysts tracking Indian federalism read Article 131 filings as barometers of Centre-State tension. UPSC candidates encounter it as a core GS-2 polity topic, where precision about its exclusivity, the legal-rights threshold, and its contrast with Articles 32 and 136 distinguishes a competent answer.
