Article 131 — Original Jurisdiction in Centre-State Disputes

Article 131 of the Constitution of India is the foundational provision governing federal dispute resolution, vesting the Supreme Court with exclusive original jurisdiction in legal disputes arising between constituent units of the Indian Union. The Article, located in Part V (The Union, Chapter IV—The Union Judiciary), was framed by the Constituent Assembly drawing on the precedent of the Government of India Act, 1935, whose Section 204 had conferred analogous original jurisdiction on the Federal Court. By "original jurisdiction," the Constitution means the Supreme Court acts as the court of first instance—the dispute commences before it rather than reaching it on appeal. The jurisdiction is termed "exclusive" because no other court in India may entertain such inter-governmental disputes, a structural recognition of the federal character that the Assembly, led by Dr. B.R. Ambedkar, sought to embed without permitting the federating units to litigate against one another in ordinary tribunals.

Article 131 specifies three categories of disputes that fall within its ambit. First, disputes between the Government of India and one or more States; second, disputes between the Government of India and any State or States on one side and one or more other States on the other; and third, disputes between two or more States. The decisive qualifier appears in the operative clause: the dispute must be one that "involves any question (whether of law or fact) on which the existence or extent of a legal right depends." This requirement of a justiciable legal right is the gatekeeper of the Article. A political grievance, a policy disagreement, or a financial demand untethered to an enforceable right does not qualify. The Supreme Court accordingly examines, at the threshold, whether the pleadings disclose a genuine legal right whose existence or extent is in contest, and it dismisses petitions that present merely commercial or factual claims dressed as constitutional disputes.

A significant limitation is carved into the proviso to Article 131. The jurisdiction does not extend to disputes arising out of any treaty, agreement, covenant, engagement, sanad, or similar instrument entered into before the commencement of the Constitution that continues in operation, or which provides that the said jurisdiction shall not extend to such a dispute. This proviso was inserted to insulate the numerous standstill agreements and instruments of accession executed with the erstwhile princely States during integration. A further restriction flows from Article 262 read with the Inter-State River Water Disputes Act, 1956, which removes water-sharing disputes between States from the Supreme Court's Article 131 jurisdiction and channels them to specialised tribunals. Money suits and disputes purely contractual in nature are likewise excluded where no constitutional legal right is engaged.

Contemporary invocations illustrate both the reach and the contested boundaries of the provision. In 2020, the State of Kerala filed an original suit under Article 131 challenging the constitutionality of the Citizenship (Amendment) Act, 2019, contending the Act violated Articles 14, 21, and 25. In 2020, the State of Chhattisgarh similarly invoked Article 131 to challenge the National Investigation Agency Act, 2008. Earlier, in State of West Bengal v. Union of India (1963), the Supreme Court heard a landmark Article 131 suit concerning the Coal Bearing Areas (Acquisition and Development) Act, holding that Indian federalism was not of the classical compact type and that States enjoyed no inviolable sovereignty against parliamentary legislation. State of Karnataka v. Union of India (1977) further clarified the maintainability of such suits.

Article 131 must be distinguished from adjacent jurisdictional provisions. It differs from Article 32, the writ jurisdiction invoked by individuals to enforce fundamental rights, which is not available to a State as a "person." It is distinct from Article 132, which governs appellate jurisdiction in constitutional matters reaching the Court from High Courts, and from Articles 133 and 134, covering civil and criminal appeals. Crucially, Article 131 confines itself to disputes between governments as juristic federal entities; a private party cannot be impleaded, and a dispute in which a private citizen is a litigant falls outside its scope. This contrasts with the writ jurisdiction of High Courts under Article 226, which States may invoke against the Union in certain administrative matters.

A persistent controversy concerns whether a State may challenge the constitutional validity of a central statute under Article 131. Conflicting two-judge benches produced divergent conclusions: State of Madhya Pradesh v. Union of India (2011) suggested such a challenge was not maintainable, while State of Jharkhand v. State of Bihar (2014) doubted that reasoning and referred the question to a larger bench. As of recent practice, the question of whether the vires of a parliamentary enactment may be tested through an original suit remains pending authoritative resolution by a larger bench, lending the Kerala and Chhattisgarh suits considerable jurisprudential weight. The Supreme Court has also clarified that Article 131 suits are governed by procedural rules under the Supreme Court Rules and require leave where appropriate.

For the working practitioner—the desk officer in a State law department, the policy researcher tracking centre-State friction, or the UPSC aspirant mastering GS Paper II federalism—Article 131 is the constitutional instrument that converts political contestation into adjudicable legal disputes. Its growing invocation by opposition-governed States against contested central legislation signals an intensifying use of the judiciary as a forum of cooperative-conflictual federalism. Understanding its threshold of a "legal right," its exclusionary proviso, and its sharp separation from writ and appellate jurisdictions equips the analyst to assess whether a centre-State confrontation will survive at the gates of the Supreme Court.
