Article 143 — Advisory Jurisdiction of the Supreme Court

Article 143 of the Constitution of India confers on the Supreme Court its advisory jurisdiction, a function distinct from its original jurisdiction under Article 131 and its appellate jurisdiction under Articles 132–136. The provision derives directly from Section 213 of the Government of India Act, 1935, which permitted the Governor-General to seek the opinion of the Federal Court. The Constituent Assembly retained the mechanism so that the executive could obtain authoritative legal guidance on grave constitutional questions before, rather than after, a politically charged crisis matured into adversarial litigation. The reference is made by the President, but because the President acts on the aid and advice of the Council of Ministers under Article 74, the power is in substance exercised by the Union Cabinet.

The procedural mechanics are set out across the two clauses of the article. Under Article 143(1), where it appears to the President that a question of law or fact has arisen, or is likely to arise, and that the question is of such a nature and public importance that it is expedient to obtain the Supreme Court's opinion, the President may refer it to the Court for consideration. The Court, after such hearing as it thinks fit, may report its opinion to the President. The word "may" is decisive: the Supreme Court is not obliged to answer a reference under clause (1) and has on occasion declined. Article 143(2) deals with disputes arising out of pre-Constitution treaties, agreements, covenants, engagements, sanads or similar instruments; here the language uses "shall," so the Court is bound to tender its opinion on such matters.

A reference is heard by a bench of at least five judges, mirroring the requirement in Article 145(3) for cases involving a substantial question of law as to the interpretation of the Constitution. The opinion is delivered as a "report" rather than a judgment, and crucially it is not binding on the President or on courts in the strict doctrine of stare decisis. Nonetheless the opinion carries enormous persuasive authority, and in practice both the executive and subordinate courts treat it as a near-definitive statement of the law. Dissenting opinions may be recorded, as occurred in several references, underlining that the Court approaches advisory matters with the same rigour it brings to contentious litigation.

Several named references illustrate the article's operation. The Delhi Laws Act reference of 1951 addressed the permissible limits of delegated legislation. In In re Kerala Education Bill (1958) the Court advised on minority educational rights under Article 30. The Berubari Union reference of 1960 examined whether the transfer of territory to Pakistan required a constitutional amendment, the Court holding that Article 3 was insufficient and a Ninth Schedule amendment was needed. The Presidential Reference of 1992 on the Cauvery water dispute, the Special Courts Bill reference of 1978, and the Third Judges Case (1998), in which the Court refined the collegium system for appointments, are further landmarks. The 2G Presidential Reference of 2012, made by the Manmohan Singh government's Cabinet through Rashtrapati Bhavan, sought clarity on whether natural resources must invariably be auctioned.

Article 143 must be distinguished from adjacent concepts. It differs from the suo motu exercise of judicial review, which the Court initiates itself; an advisory reference is initiated by the executive. It differs from the original jurisdiction under Article 131, which adjudicates federal disputes between the Union and States in a binding contest with defined parties. It is also distinct from a curative or review petition, which reopens a decided case. Unlike the United States Supreme Court, which has refused advisory opinions since Muskrat v. United States (1911) on grounds of the "case or controversy" requirement, the Indian Supreme Court accepts a deliberate constitutional design borrowed from the Canadian reference procedure under Section 53 of the Supreme Court Act.

Controversy surrounds the article on two fronts. First, the Court has guarded its discretion under clause (1): in the Special Reference No. 1 of 1964 (the Keshav Singh case concerning legislative privilege) and elsewhere it affirmed it could decline a reference for sufficient reason, and in the Ayodhya reference of 1993 (Ismail Faruqui) the Court returned the question of whether a temple pre-existed the Babri Masjid unanswered, deeming it superfluous and favouring one community. Second, critics argue that successive governments have used Article 143 to shift politically inconvenient decisions onto the judiciary, blurring the separation of powers. The mechanism cannot be invoked to override a binding judgment or to seek reconsideration of settled law, a limit the Court has reiterated.

For the working practitioner—the civil servant drafting a Cabinet note, the policy researcher mapping centre-State friction, or the journalist covering a constitutional standoff—Article 143 is the principal channel through which the executive secures pre-emptive judicial clarity without precipitating a full adversarial dispute. Understanding that the opinion is persuasive but non-binding, that clause (2) references are mandatory while clause (1) references are discretionary, and that a five-judge bench is the minimum, equips the analyst to assess when a government's recourse to a Presidential Reference signals genuine legal uncertainty and when it functions as a calculated deferral of accountability.
