writ

A writ is a peremptory written command issued by a court in the exercise of its constitutional or statutory jurisdiction, directing a public official, body, or private person to do or abstain from a specified act. In Indian constitutional law the power flows from two provisions: Article 32, which empowers the Supreme Court to issue writs for the enforcement of Fundamental Rights, and Article 226, which empowers every High Court to issue writs both for Fundamental Rights and "for any other purpose" — a wider sweep than the apex court's. The concept is inherited from the English common-law prerogative writs administered by the Court of King's Bench; the Constitution names five of them — habeas corpus, mandamus, prohibition, certiorari, and quo warranto — and grants courts the freedom to mould relief beyond their classical forms. Dr B.R. Ambedkar called Article 32 the "heart and soul" of the Constitution, and L. Chandra Kumar v. Union of India (1997) held that the writ jurisdiction of the higher judiciary is part of the basic structure, beyond amendment.

Each writ has a distinct function. Habeas corpus ("you may have the body") tests the legality of any detention and may be sought even by a stranger to the detenu. Mandamus ("we command") compels a public authority to perform a mandatory public duty it has refused; it does not lie against the President, governors, or a private individual without a statutory duty. Prohibition is preventive, issued by a superior court to stop an inferior court or tribunal from exceeding its jurisdiction while proceedings are pending; certiorari ("to be certified") is curative, quashing an order already passed without jurisdiction, in violation of natural justice, or vitiated by an error of law apparent on the face of the record. Quo warranto ("by what authority") questions the legal title of a person holding a public office of substantive character created by statute or the Constitution.

A crucial distinction governs the two articles: the right to move the Supreme Court under Article 32 is itself a Fundamental Right and cannot ordinarily be refused, whereas the High Court's power under Article 226 is discretionary though territorially wider. During the Emergency, ADM Jabalpur v. Shivkant Shukla (1976) infamously suspended habeas corpus, a ruling expressly overruled in K.S. Puttaswamy v. Union of India (2017). The expansion of locus standi through Public Interest Litigation — S.P. Gupta (1981), Bandhua Mukti Morcha (1984) — transformed writs into instruments of mass social justice. As of 2026 writ petitions remain the principal vehicle of judicial review in India.

For the UPSC examination, writs are core to the Indian Polity portion of GS Paper II (Prelims and Mains), tested under the Judiciary, Fundamental Rights, and judicial review. Prelims frequently demands precise matching — which writ lies against whom, the prohibition-versus-certiorari timing distinction, and that only the High Court may act "for any other purpose." Mains questions probe Article 32 versus Article 226, the basic-structure status of writ jurisdiction, and the role of PIL in widening access to constitutional remedies.
