The Indian Supreme Court’s powers and jurisdiction make it the final constitutional authority in the country: it decides disputes between the Union and the states, hears appeals from every court and tribunal below it, enforces fundamental rights directly through writs, reviews the constitutionality of laws passed by Parliament and state legislatures, and can pass whatever order is needed to do complete justice in a case before it. Its rulings bind every other court in India. Understanding what the Court can actually do means looking at each of these powers in turn, because they operate under different constitutional articles and reach different kinds of problems.
Judicial Review and the Basic Structure Doctrine
The Court’s authority to strike down laws is its most consequential power. Article 13 of the Constitution provides that any law taking away or limiting fundamental rights is void to the extent of that conflict.1Indian Kanoon. Constitution of India – Article 13 On that foundation the Court has invalidated legislation across free speech, property, personal liberty, and much else.
In 1973 the Court went further. By a 7-6 majority in Kesavananda Bharati v. State of Kerala, it held that the Constitution has a “basic structure” Parliament cannot alter even through a formal constitutional amendment. Democracy, secularism, federalism, rule of law, and judicial review itself were placed beyond the amending power.2eCourts India. The Basic Structure Judgment The doctrine has no explicit textual basis; it is a judicial creation, and the Court has used it repeatedly in the decades since to strike down amendments that threaten core constitutional values.
Original Jurisdiction Over Federal Disputes
Article 131 gives the Supreme Court exclusive original jurisdiction over certain federal disputes. These are filed directly in the Supreme Court rather than appealed from below, and they are limited to disputes between the central government and one or more states, or between two or more states, where the case turns on a question of law or fact involving legal rights.3Constitution of India. Article 131 – Original Jurisdiction of the Supreme Court Boundary disagreements, resource-sharing fights, and challenges to the distribution of tax revenue are typical examples. Private citizens and corporations cannot invoke Article 131; they must enter the system through the lower courts.
Appellate Jurisdiction
The Supreme Court is the final court of appeal in India. Three constitutional provisions govern how cases reach it from the High Courts. Article 132 covers appeals that raise a substantial question of constitutional interpretation. Article 133 handles civil matters where a significant legal question of general importance needs resolution. Article 134 governs criminal appeals.4Indian Kanoon. Constitution of India – Article 1325Indian Kanoon. Constitution of India – Article 133
For constitutional and civil appeals, the High Court must certify that the case raises a substantial legal question worthy of Supreme Court review. Certification is a gatekeeping mechanism: if the High Court believes the law is already settled, it can refuse the certificate, keeping routine disputes out of the apex court. Under Article 134A, a party can make an oral application for the certificate immediately after the High Court delivers its judgment, and the High Court must then decide the question promptly.
Criminal appeals have a more direct route in two high-stakes situations. An appeal lies to the Supreme Court as of right when a High Court has reversed an acquittal and imposed a death sentence, or when a High Court has withdrawn a case from a lower court, tried it, and sentenced the accused to death.6Indian Kanoon. Constitution of India – Article 134 All other criminal cases need certification. The automatic appeal in death-sentence situations reflects a straightforward principle: the most irreversible punishment demands the most thorough review.
Special Leave to Appeal Under Article 136
Article 136 is the Supreme Court’s extraordinary backstop. It allows the Court to grant special leave to appeal from any judgment or order passed by any court or tribunal in India.7Constitution of India. Article 136 – Special Leave to Appeal by the Supreme Court This is not a right that belongs to the litigant. It is a discretionary power the Court exercises when it believes a serious injustice has occurred that ordinary appeal channels cannot fix. In practice, a large share of the Court’s docket arrives through Article 136, and the breadth of the provision means no legal order in the country is truly beyond its reach.
Writ Jurisdiction for Fundamental Rights
Article 32 lets any person approach the Supreme Court directly when a fundamental right has been violated. No certificate from a lower court is needed, no prior ruling is required. It is an independent, self-contained remedy, and it is itself a fundamental right.8Constitution of India. Constitution of India – Article 32 – Remedies for Enforcement of Rights Conferred by This Part
The Court enforces those rights by issuing writs, each designed for a specific situation:
- Habeas corpus orders the release of a person detained without lawful authority.
- Mandamus compels a public official or government body to perform a legal duty they have failed or refused to carry out.
- Prohibition stops a lower court or tribunal from exceeding its legal authority in an ongoing proceeding.
- Certiorari quashes an order a lower court or tribunal has already passed without proper jurisdiction.
- Quo warranto challenges whether a person holding a public office is legally entitled to occupy it.
Writs operate against the state and its agencies. A private company or individual generally cannot be targeted unless they perform a public function resembling a government duty. The Court reinforced that boundary in its 2025 decision in S. Shobha v. Muthoot Finance Ltd., holding that a private financial institution regulated by the Reserve Bank of India does not become subject to writ jurisdiction simply because it follows government regulations.8Constitution of India. Constitution of India – Article 32 – Remedies for Enforcement of Rights Conferred by This Part Regulatory oversight alone is not enough; the entity must actually be carrying out a sovereign function.
Public Interest Litigation
Traditional procedure requires a direct personal stake in a case before filing it. The Supreme Court dismantled that requirement through Public Interest Litigation, pioneered by Justices P.N. Bhagwati and V.R. Krishna Iyer in the late 1970s and early 1980s. Under PIL, any public-spirited citizen can petition the Court on behalf of people too poor, too marginalized, or too disadvantaged to approach the courts themselves.
The Court has extended this through what is called epistolary jurisdiction: treating informal letters or postcards from ordinary citizens as formal writ petitions. A prisoner writing to the Chief Justice about jail conditions can trigger a full constitutional proceeding. The Court can also act on its own initiative, taking notice of media reports or other information about rights violations without any petition being filed. This power has reached environmental degradation, sexual violence, and the provision of essential services during the COVID-19 pandemic.
PIL turned the Supreme Court from a passive adjudicator into an institution that actively reaches out to protect vulnerable populations. Critics have said the Court sometimes oversteps into areas better left to elected officials. For millions of Indians who lack the resources to navigate formal legal channels, PIL remains the most accessible route to constitutional protection.
Complete Justice Under Article 142
Article 142 authorizes the Supreme Court to pass whatever decree or order is necessary to do “complete justice” in any matter pending before it, and that order is enforceable throughout the country.9Constitution of India. Article 142 – Enforcement of Decrees and Orders of Supreme Court This is the Court’s broadest and most flexible power. It has been used to dissolve marriages where no statutory ground for divorce existed, to shut down polluting industries, and to direct the government to implement policies. Article 142 is what allows the Court to fashion remedies beyond what any specific statute contemplates, filling gaps where rigid application of existing rules would produce an unjust result.
Advisory Jurisdiction
Article 143 lets the President refer questions of law or fact that carry significant public importance to the Supreme Court for an opinion. One boundary matters here: the Court is not strictly required to answer every reference, and its opinion does not function as a binding judgment. It does not carry the force of “law declared” under Article 141, so lower courts are not bound to follow it. The opinions carry heavy persuasive weight and often shape how the government approaches legislation, but they are advice, not command.
Review and Curative Petitions
After the Supreme Court delivers a final judgment, two narrow avenues for correction remain. Under Article 137, the Court can review its own decisions to fix errors apparent on the face of the record or consider significant new evidence that was previously unavailable.10Constitution of India. Article 137 – Review of Judgments or Orders by the Supreme Court Review petitions are typically heard without oral arguments, in chambers, and succeed only rarely.
If a review petition fails, one last option exists: the curative petition, established by the Court in Rupa Ashok Hurra v. Ashok Hurra (2002). The grounds are extremely narrow. A curative petition can be entertained only where the original judgment was passed without jurisdiction, where principles of natural justice were violated, or where bias or unfair procedure resulted in an abuse of the Court’s process. The petitioner must also obtain certification from a senior advocate that permissible grounds exist before the Court will even look at it.11Manupatra. Rupa Ashok Hurra v Ashok Hurra and Ors The rarity of successful curative petitions signals the Court’s strong preference for letting decided matters rest.
Binding Precedent and Court of Record Status
Article 129 declares the Supreme Court to be a court of record, meaning its proceedings are permanently documented and its decisions carry the authority of established precedent. The status also gives the Court the power to punish for contempt of itself, which is how it enforces compliance with its orders.12Constitution of India. Article 129 – Supreme Court to Be a Court of Record
Article 141 goes further by providing that the law declared by the Supreme Court is binding on all courts throughout India.13Constitution of India. Article 141 – Law Declared by Supreme Court to Be Binding on All Courts When the Supreme Court interprets a statute or a constitutional provision, that interpretation becomes the governing rule for every High Court, district court, and tribunal in the country. This is how the Court maintains legal uniformity across 25 High Courts and thousands of subordinate courts.
Who Can File a Case
Not every lawyer can file in the Supreme Court. Only an Advocate-on-Record has the right to file petitions, submit motions, and represent clients directly before the Court. To earn the designation, a practicing advocate must have at least five years of experience, complete one year of training under an existing Advocate-on-Record, and pass an annual examination covering Supreme Court rules, drafting, and legal ethics. After passing, the advocate must maintain an office in Delhi within a prescribed distance from the Court and employ a registered clerk. Senior Advocates, designated separately based on ability and standing, cannot file cases directly or appear without being briefed by an Advocate-on-Record. The division keeps courtroom advocacy and procedural filing work in different hands.
