Supreme Court Case Types

The Supreme Court of India hears several distinct types of cases, each with its own basis in the Constitution or statute. The most common are Special Leave Petitions (SLPs), civil and criminal appeals, and writ petitions under Article 32.

Overview

The Supreme Court of India exercises three kinds of jurisdiction: original, appellate, and advisory. Most cases reach the Supreme Court through its appellate jurisdiction — specifically through a filing called a Special Leave Petition (SLP). The Court also directly entertains petitions when fundamental rights are at stake, and it may advise the President of India on legal questions of public importance.

Understanding which type of case you are tracking matters because the case number format, the procedural steps, and even the scope of the Court's powers differ across these types. A case number like SLP(C) No. 4502/2024 tells you immediately that the matter started as a civil leave petition. A number like WP(C) No. 1200/2023 tells you that someone filed directly in the Supreme Court to enforce a fundamental right.

Special Leave Petition (SLP)

The Special Leave Petition is the most common route to the Supreme Court. It is governed by Article 136 of the Constitution, which gives the Supreme Court discretion to grant special leave to appeal from any judgment, decree, order, or sentence passed by any court or tribunal in the country. The word "discretion" is important — filing an SLP does not guarantee that the Supreme Court will hear your case.

An SLP is a request for permission to appeal. The petitioner is essentially asking the Court: "Please allow us to argue this matter before you." The Court may grant leave, dismiss the petition outright, or pass an ad-interim order (such as a stay) while considering whether to grant leave.

SLP(C) vs. SLP(Crl)

SLPs are split into two tracks based on the nature of the underlying dispute:

• SLP(C) — Civil track: Covers property disputes, contract matters, family law, arbitration awards, service matters, and most other civil proceedings.
• SLP(Crl) — Criminal track: Covers challenges to HC orders in criminal cases — bail rejections, convictions, sentences, and quashing petitions.

The number format follows this pattern: SLP(C) No. XXXX/YYYY or SLP(Crl) No. XXXX/YYYY, where XXXX is the serial number and YYYY is the year of filing. When you look up a case on casestatus.in, this number is what you will use.

What Happens After an SLP is Filed

• Notice and listing: The SLP is listed before a bench (usually two judges). The Court may issue a notice to the opposite party or dismiss at the admission stage itself.
• Leave granted: The SLP converts to a Civil Appeal (CA) or Criminal Appeal (CrA) with a new case number. Full arguments are scheduled.
• Leave dismissed: The HC or tribunal order stands. The Court may give brief reasons.
• Disposed with direction: The Court sometimes resolves the matter at the SLP stage itself — without converting to an appeal — by passing final orders after hearing both parties briefly.

Civil Appeals

A Civil Appeal is a full appeal before the Supreme Court on the merits. Civil Appeals reach the Supreme Court in two ways:

• Certificate of fitness (Article 133): If the High Court is satisfied that the case involves a substantial question of law of general importance, it can certify the case for appeal to the Supreme Court. The High Court grants this certificate before the case goes up. This route is relatively rare because High Courts are cautious about certifying.
• Converted from SLP: Far more commonly, a Civil Appeal is created when the Supreme Court grants leave on an SLP(C). The SLP is admitted and re-numbered as a Civil Appeal.

The case number format is CA No. XXXX/YYYY. Civil Appeals are heard by benches of two judges (Division Bench) for most matters, and by three or more judges for constitutional questions.

Criminal Appeals

Criminal Appeals follow a similar pattern but are governed by Article 134 and the Code of Criminal Procedure. There are two ways a criminal case reaches the Supreme Court directly:

• As of right (Article 134): If a High Court has (a) reversed an acquittal and sentenced the accused to death, (b) sentenced a person to death on appeal from a lower court, or (c) certified the case as fit for appeal to the Supreme Court, then the accused has a right of appeal without seeking the Court's leave.
• Via SLP(Crl): In all other criminal matters — bail orders, sentence enhancements, quashing orders, convictions where no death sentence is involved — the route is through an SLP(Crl), which converts to a Criminal Appeal (CrA) if leave is granted.

The case number is CrA No. XXXX/YYYY. In high-profile criminal cases, you may see the Supreme Court grant interim bail while the appeal is pending — this happens during the SLP stage and carries over once the case converts to a Criminal Appeal.

Writ Petitions Under Article 32

The Supreme Court is the guardian of fundamental rights under Part III of the Constitution. Article 32 gives every citizen the right to move the Supreme Court directly — without first going to a High Court — if a fundamental right has been violated or is threatened.

This is a significant power. In most legal systems, you must exhaust lower courts before approaching the highest court. Article 32 is an exception: it is itself a fundamental right. The Supreme Court has called it the "heart and soul of the Constitution."

WP(C) vs. WP(Crl)

• WP(C) — Civil writ: Covers violations of fundamental rights in non-criminal contexts — right to equality, right against discrimination, right to livelihood, environmental rights (when framed as a right to life under Article 21), and challenges to state action.
• WP(Crl) — Criminal writ: Primarily used for habeas corpus petitions (to secure the release of a person detained without lawful authority) and other personal liberty violations under Article 21.

Transfer Petitions

A Transfer Petition asks the Supreme Court to move a pending case from one court to another — typically from one High Court to a different High Court, or from a lower court to the Supreme Court itself. The power to transfer cases is granted under Article 139A (for cases pending in High Courts involving common questions of law) and Section 406 of the Code of Criminal Procedure (for criminal cases).

Transfer Petitions are particularly common in matrimonial disputes. When a husband and wife are litigating divorce or maintenance proceedings in courts located in different states, one party often files a Transfer Petition to consolidate the cases in a single court. The Supreme Court considers factors like the convenience of the parties, the interests of justice, and whether a fair trial is possible in the original court.

Case numbers take the form TP(C) No. XXXX/YYYY for civil transfers and TP(Crl) No. XXXX/YYYY for criminal transfers.

Curative Petitions

A Curative Petition is the last legal remedy available in the Indian court system. After a final judgment by the Supreme Court and after a Review Petition against that judgment has also been dismissed, a litigant may file a Curative Petition asking the Court to reconsider its own decision.

This remedy was created by the Supreme Court itself in the case of Rupa Ashok Hurra v. Ashok Hurra (2002). The Court recognised that its duty to do complete justice sometimes required it to correct errors even after the review stage. However, the grounds for a Curative Petition are narrow:

• A violation of the principles of natural justice — for example, a party was not heard before the order was passed against them.
• A Judge who heard the Review Petition had a real or apparent conflict of interest and should have recused but did not.

Curative Petitions are rarely admitted. They are first circulated to the three most senior judges of the Court and to the judges who delivered the original judgment. If they conclude that there is a case for hearing, the petition is listed before the same bench. In most cases, the petition is dismissed in chambers without an open court hearing.

Contempt Petitions

The Supreme Court's power to punish for contempt flows from Article 129 of the Constitution, which declares the Supreme Court a court of record with the power to punish for contempt of itself. A Contempt Petition is filed when a party believes that another person has wilfully disobeyed a Supreme Court order.

Contempt proceedings can also begin on the Court's own motion (suo motu) — when a judge notices what appears to be deliberate non-compliance or a public statement that scandalises the Court.

Case numbers follow the format Conmt.Pet.(C) No. XXXX/YYYY for civil contempt and Conmt.Pet.(Crl) No. XXXX/YYYY for criminal contempt. Civil contempt means wilful disobedience of a court order. Criminal contempt covers acts that scandalise or tend to scandalise, or lower or tend to lower, the authority of the Court.

Miscellaneous and Interlocutory Applications

Within any pending case — whether an SLP, Civil Appeal, Writ Petition, or any other matter — parties may file applications for interim relief or procedural directions. These are called Interlocutory Applications (IA). An IA is not a separate case; it is filed inside an existing case number and carries its own sub-number (for example, IA No. 3 in CA No. 8001/2024).

Common IAs include applications for stay of HC orders, applications to condone delay in filing, applications to implead additional parties, and applications for early hearing of a matter (urgent mention).

Before a case is formally registered, urgent matters may be given a Diary Number. When a litigant files papers urgently and they have not yet been allotted a regular case number, the case is identified by its diary number in the registry. Once registered, it gets a standard case number and the diary number is retired.

A Worked Example: SLP to Civil Appeal

Consider Priya, who runs a small export firm in Delhi. Her company entered into a contract with a supplier, a dispute arose, and the matter went to arbitration. The arbitration tribunal awarded ₹2 crore in damages against Priya's company. She challenged the award before the Delhi High Court, but a Division Bench of the High Court upheld the award. Priya now wants to take the matter to the Supreme Court.

Here is how the case would proceed:

• Step 1 — File SLP(C): Priya's advocates file an SLP(C) in the Supreme Court challenging the Delhi HC Division Bench order. The matter is registered as, say, SLP(C) No. 7845/2025.
• Step 2 — First listing: The case comes before a two-judge bench. The bench issues notice to the supplier and, if it finds a prima facie case, may grant a stay on execution of the ₹2 crore award.
• Step 3 — Leave granted: After hearing brief arguments from both sides, the bench is satisfied that the case raises a substantial legal question about the scope of judicial review of arbitration awards. Leave is granted. The SLP converts to Civil Appeal No. 1234/2025. From this point, the case is tracked by the CA number.
• Step 4 — Full hearing: Dates are fixed for full arguments. Both sides file written submissions. The bench delivers its judgment after hearing oral arguments.

If the Supreme Court had dismissed the SLP at Step 3, the Delhi HC order would have stood and Priya would have had no further remedy (other than a Review Petition, and if dismissed, a Curative Petition on narrow grounds). The SLP-to-Civil Appeal pathway is the standard route for commercial and civil disputes that reach the Supreme Court.
