A writ of certiorari is an order through which a higher court directs a lower court to send the record of a case for review. The term is most commonly associated with the U.S. Supreme Court, which uses certiorari to decide which cases it will hear.
Unlike an ordinary appeal, Supreme Court review through certiorari is usually discretionary. The Court does not have to accept every case presented to it, even when a party claims that a lower court made a serious legal error.
A party seeking Supreme Court review files a petition for a writ of certiorari. If the Court grants the petition, it issues the writ and agrees to review the case. If the Court denies the petition, the lower court’s judgment generally remains in effect.
What Does Certiorari Mean?
The word certiorari comes from Latin and is commonly translated as “to be more fully informed” or “to be made certain.”
Historically, higher courts used the writ to call up records from lower courts or government bodies. Reviewing the record allowed the higher court to determine whether the lower tribunal had acted within its authority or applied the law correctly.
In modern American law, the term usually refers to discretionary appellate review, particularly by the U.S. Supreme Court.
The word is often shortened to cert. in legal writing. For example:
- Cert. granted means the Court agreed to hear the case.
- Cert. denied means the Court declined to review the case.
- Cert. petition means a petition asking the Court to grant review.
Petition for Certiorari vs. Writ of Certiorari
A petition for certiorari and a writ of certiorari are closely related, but they are not the same thing.
| Term | Meaning |
| Petition for a writ of certiorari | A filing asking a higher court to review a lower-court decision |
| Writ of certiorari | The order issued after the higher court accepts the case |
| Grant of certiorari | The court agrees to review the case |
| Denial of certiorari | The court declines to review the case |
A party does not technically “file a writ.” The party files a petition requesting the writ. The court decides whether the writ should be issued.
This distinction is important because the petition is only a request. Filing it does not guarantee that the Supreme Court will review the case.
What Is the Purpose of a Writ of Certiorari?
The writ of certiorari gives a higher court control over its discretionary docket. It allows the Supreme Court to focus its limited time and resources on cases involving important questions of federal law.
The Court does not usually grant certiorari simply to correct an error that affects only the parties involved. Instead, it often looks for issues that have broader legal importance.
For example, the Court may accept a case to:
- Resolve conflicting interpretations of federal law
- Decide an important constitutional question
- Clarify the meaning of a federal statute
- Address a lower-court ruling that conflicts with Supreme Court precedent
- Settle a legal issue affecting courts throughout the country
- Review a serious departure from accepted judicial procedures
Certiorari therefore serves both a procedural and an institutional purpose. It gives parties a way to request review while allowing the Supreme Court to choose cases that may shape federal law nationally.
How Does a Writ of Certiorari Work?
The certiorari process usually follows several stages.
A Lower Court Issues a Decision
The process begins after a lower court enters a decision that may qualify for Supreme Court review.
The case commonly comes from:
- A U.S. court of appeals
- A state supreme court
- Another state court of last resort
- A lower state court when no further state review is available
- The U.S. Court of Appeals for the Armed Forces
In most cases, the decision must be final. The Supreme Court generally avoids reviewing disputes that are still moving through lower courts.
The Petitioner Files a Petition
The party seeking review is called the petitioner.
The petition explains what happened in the case, identifies the legal questions involved, and argues why those questions are important enough for Supreme Court review.
A strong petition normally focuses on a clear issue of federal law rather than asking the Court to reconsider every factual or legal dispute in the case.
The Respondent May Oppose Review
The opposing party is called the respondent.
The respondent may file a brief in opposition, explaining why the Court should deny the petition. The respondent might argue that there is no conflict among lower courts, that the issue is unimportant, or that the case has a procedural problem.
The respondent may also initially waive the right to file a response. The Court can still request a response before deciding the petition.
The Petitioner May Reply
The petitioner may file a reply brief addressing the respondent’s arguments.
A reply might explain why a claimed procedural problem does not prevent review or why a conflict among courts is more significant than the respondent suggests.
The Justices Consider the Petition
The petition and related briefs are distributed to the justices.
The justices may discuss the case in a private conference. They consider whether the legal question is important, whether the case is suitable for review, and whether Supreme Court intervention is necessary.
The Court Grants or Denies the Petition
If at least four justices vote to hear the case, certiorari is granted.
If fewer than four justices vote in favor of review, the petition is usually denied.
The Court generally announces the result through a short order.
What Is the Rule of Four?
The Rule of Four is the Supreme Court practice under which at least four of the nine justices must vote to grant certiorari.
The rule allows a substantial minority of the Court to place a case on the merits docket. Five votes are usually needed to form a majority decision after the case is argued, but only four are required to accept the case for review.
The Rule of Four is not written in the U.S. Constitution. It is a long-standing internal practice followed by the Court.
A vote to grant certiorari does not necessarily reveal how a justice will decide the case. A justice may believe the issue deserves review but ultimately vote to affirm the lower court.
Is a Writ of Certiorari the Same as an Appeal?
A writ of certiorari is related to appellate review, but it is not the same as an appeal as of right.
An appeal as of right is one that a reviewing court must generally hear when the filing requirements and jurisdictional rules are satisfied.
A petition for certiorari asks for discretionary review. The Supreme Court may decline the case even if the petition is timely and raises a genuine legal question.
| Writ of Certiorari | Appeal as of Right |
|---|---|
| Review is discretionary | Review is generally mandatory |
| The court selects the cases it hears | The court must usually hear a proper appeal |
| Most petitions are denied | Proper appeals ordinarily receive a decision |
| Broader legal importance is often required | An error affecting the parties may be enough |
| Denial does not address the merits | The appellate court generally rules on the case |
People sometimes refer informally to “appealing to the Supreme Court.” In most cases, however, the party is asking the Court to exercise discretionary certiorari jurisdiction.
Why Does the Supreme Court Grant Certiorari?
The Supreme Court grants certiorari for compelling reasons. Several factors can make a petition more likely to receive review.
A Circuit Split
A circuit split occurs when two or more federal courts of appeals interpret the same federal law differently.
For example, one circuit may decide that a federal statute permits a certain type of lawsuit, while another circuit holds that the same statute bars it.
A circuit split creates different legal rules in different parts of the country. The Supreme Court may grant certiorari to establish one nationwide interpretation.
An Important Federal Question
The Court may accept a case presenting an important and unresolved question involving the Constitution, a federal statute, a treaty, or another matter of federal law.
The issue usually must have significance beyond the immediate dispute.
Conflict With Supreme Court Precedent
Certiorari may be appropriate when a lower court decides an important federal issue in a way that conflicts with an earlier Supreme Court decision.
Conflict Among State Courts
The Court may also review a federal question when state courts of last resort disagree about how federal law should be interpreted.
Serious Procedural Departure
The Court may intervene when a lower court significantly departs from accepted judicial procedures, particularly when the departure affects important federal interests.
What Makes a Case Cert-Worthy?
A case considered suitable for Supreme Court review is sometimes described as cert-worthy.
A cert-worthy case often includes:
- A clear legal issue
- A genuine conflict among lower courts
- A question of national importance
- A final judgment
- A well-developed factual record
- Proper preservation of the issue
- A direct conflict with Supreme Court precedent
- Few procedural complications
The Court is less likely to grant review when the case contains a vehicle problem.
What Is a Vehicle Problem?
A vehicle problem is a procedural, jurisdictional, or factual issue that could prevent the Supreme Court from deciding the question presented clearly.
Examples include:
- The legal issue was not raised in the lower court
- The lower-court judgment is not final
- The case has become moot
- The petitioner lacks standing
- The facts are disputed or unclear
- State law independently supports the judgment
- The legal question would not change the outcome
- The petition describes a conflict that does not actually exist
- Another issue would need to be decided first
A case may involve an important legal question and still be denied because it is not the right vehicle for resolving that question.
What Happens When Certiorari Is Granted?
When the Supreme Court grants certiorari, it agrees to review the case.
A grant does not mean the lower court was wrong. It means at least four justices believe the case deserves full consideration.
After certiorari is granted:
- The lower-court record becomes available to the Supreme Court.
- The petitioner files a merits brief.
- The respondent files a merits brief.
- The petitioner may file a reply.
- Interested nonparties may submit amicus curiae briefs.
- The Court may schedule oral argument.
- The justices discuss and vote on the case.
- The Court issues an opinion or another order.
The Court may limit review to only one of the questions raised in the petition.
What Happens When Certiorari Is Denied?
When certiorari is denied, the Supreme Court declines to review the case.
The lower-court judgment remains in effect, but the denial does not mean the Supreme Court agrees with the lower court.
A denial of certiorari does not:
- Approve the lower court’s reasoning
- Create Supreme Court precedent
- Mean the petition was frivolous
- Establish that the lower court was correct
- Reveal how every justice viewed the case
The Court usually does not explain why it denied review. A case may be denied because it lacks national importance, has a procedural problem, presents an undeveloped issue, or fails to receive four votes.
Occasionally, one or more justices write an opinion agreeing with or disagreeing with the denial. These separate writings are unusual and do not change the fact that the Court declined full review.
Can the Supreme Court Review State-Court Cases?
The Supreme Court can review certain state-court decisions, but its authority is limited.
The case must generally involve a federal question, such as:
- A right protected by the U.S. Constitution
- The interpretation of a federal statute
- The validity of a state law under federal law
- A federal treaty
- A claim that state action violates federal rights
The Court does not usually review a state-court decision based entirely on state law.
Adequate and Independent State Grounds
The Supreme Court normally cannot change the result when a state-court judgment rests on an adequate and independent state-law ground.
For example, if a state court rejects a claim based on both federal law and a separate state procedural rule that independently supports the result, Supreme Court review may not affect the judgment.
The federal issue must also usually have been raised and preserved during the state-court proceedings.
How Long Do You Have to File a Certiorari Petition?
A petition for a writ of certiorari is generally due within 90 days after entry of the relevant lower-court judgment or order.
The deadline usually runs from the judgment date rather than the date the appellate mandate is issued.
A timely petition for rehearing may change when the 90-day period begins. A justice may also extend the filing period for good cause, subject to the Court’s rules.
Certiorari deadlines are highly technical. Missing a deadline can prevent the Court from considering the petition, so parties should not rely on general summaries when calculating filing dates.
What Is Included in a Certiorari Petition?
A petition for certiorari contains several important sections.
Questions Presented
The questions presented identify the specific legal issues the petitioner wants the Court to decide.
They should be concise, clear, and focused on important federal law.
List of Parties and Related Proceedings
The petition identifies the parties and may disclose related cases or proceedings.
Opinions Below
The petition cites the lower-court opinions and includes relevant decisions in an appendix.
Jurisdictional Statement
This section identifies the statute authorizing Supreme Court review and explains why the petition is timely.
Constitutional or Statutory Provisions
The petition includes the legal provisions involved in the dispute.
Statement of the Case
This section summarizes the procedural history and relevant facts.
Reasons for Granting the Petition
The petitioner explains why the case deserves review, often pointing to a circuit split, national importance, or conflict with Supreme Court precedent.
Appendix
The appendix generally includes lower-court judgments, opinions, orders, and other necessary materials.
What Is a Brief in Opposition?
A brief in opposition is the respondent’s written explanation of why the Supreme Court should deny certiorari.
The respondent may argue that:
- No real circuit split exists
- The issue is not important
- The lower court correctly applied existing law
- The case has procedural defects
- The question was not preserved
- The case is a poor vehicle
- Further lower-court review is needed
A brief in opposition is not always required unless the Court requests one or specific rules make a response necessary.
What Is an Amicus Curiae Brief?
An amicus curiae brief is filed by a person or organization that is not a party to the case but has information, expertise, or an interest in the legal issue.
At the certiorari stage, an amicus brief may explain why the question has broad importance or why a conflict among courts is causing practical problems.
Amicus support can help show that a dispute affects more than the immediate parties, although it does not guarantee review.
What Is a Certificate of Service?
A certificate of service confirms that required documents were provided to the other parties or their attorneys.
It usually states:
- Who received the filing
- The addresses used
- The method of delivery
- The date of service
- The filer’s certification
Filing a document with the Court and serving it on the opposing parties are separate procedural requirements.
What Is the Supreme Court Docket?
The Supreme Court docket is the official record of activity in a case.
It may show:
- The filing date
- The docket number
- Extension requests
- Waivers
- Briefs in opposition
- Reply briefs
- Amicus briefs
- Distribution dates
- Requests for responses
- Orders granting or denying certiorari
- Oral argument dates
- Final decisions
The docket shows what happened procedurally but may not explain why the Court took a particular action.
What Is Certiorari Before Judgment?
Certiorari before judgment allows the Supreme Court to accept a case before a federal court of appeals has issued its final judgment.
This procedure is extraordinary. It bypasses the normal appellate path and is generally reserved for matters of imperative public importance requiring immediate Supreme Court resolution.
In an ordinary case, the process is:
- Trial court decision
- Court of appeals judgment
- Petition for certiorari
With certiorari before judgment, the Supreme Court may intervene while the appeal is still pending.
Urgency alone does not guarantee review. The case must present exceptional circumstances.
Other Possible Certiorari Outcomes
The Supreme Court has options beyond simply granting or denying a petition.
Grant, Vacate, and Remand
A GVR order means the Court grants the petition, vacates the lower-court judgment, and sends the case back for reconsideration.
This may occur after a new Supreme Court decision, a change in law, or another development affecting the case.
Hold
The Court may hold a petition while it decides another case involving a related issue.
Call for the Views of the Solicitor General
The Court may ask the U.S. solicitor general to provide the federal government’s position. This is sometimes abbreviated as CVSG.
Dismissed as Improvidently Granted
The Court may grant certiorari and later decide that review was a mistake. It may then dismiss the case as improvidently granted, commonly called a DIG.
Frequently Asked Questions About Writs of Certiorari
Does “Cert. Denied” Mean the Lower Court Was Right?
No. When the Supreme Court denies certiorari, it means only that the Court has decided not to review the case. The denial does not approve the lower court’s reasoning, establish a nationwide precedent, or express an opinion about whether the decision was correct. The lower court’s ruling remains in effect for the parties, but the Supreme Court may decline review for many reasons unrelated to the merits.
Can the Supreme Court Grant Only Part of a Petition?
Yes. The Supreme Court may grant certiorari for one or more specific questions while declining to consider the other issues presented in the petition. The Court can also rewrite or narrow the question it agrees to review. Briefing and oral argument will generally focus on the accepted question rather than every argument raised in the case.
Why Does the Supreme Court Deny Most Petitions?
The Supreme Court receives thousands of petitions each term but has the capacity to hear only a small percentage of them. Many petitions concern alleged errors that affect only the parties rather than an important issue of federal law. The Court is more likely to grant review when lower courts disagree, an important federal question remains unresolved, or a lower court has departed from Supreme Court precedent. A denial does not necessarily mean the petition lacked merit.
Is a Circuit Split Required for Certiorari?
No. A circuit split is not an absolute requirement, but it can provide a strong reason for the Supreme Court to hear a case. A split occurs when federal courts of appeals reach different conclusions about the same federal legal issue, causing the law to apply differently across jurisdictions. The Court may also grant certiorari to resolve an important constitutional question, review a conflict involving state supreme courts, correct a serious departure from precedent, or address another issue of national importance.
Does Granting Certiorari Mean the Petitioner Will Win?
No. Granting certiorari means only that the Supreme Court has agreed to review a specific legal question in the case. It does not indicate that a majority of the justices agrees with the petitioner’s position. After reviewing briefs, hearing oral arguments, and examining the record, the Court may affirm, reverse, or modify the lower court’s decision. It may also dismiss the case without deciding the central issue if a procedural problem arises.
