Petition for a Writ of Certiorari

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

What is a petition for certiorari, and when is it due?

A petition for a writ of certiorari asks the Supreme Court to review your court of appeals decision. It is due within 90 days after entry of the judgment — not from the mandate. Review “is not a matter of right, but of judicial discretion,” granted “only for compelling reasons,” and the Court grants a very small fraction of the petitions it receives. Meanwhile, your § 2255 clock is affected by what you decide.

Key takeaways on the certiorari petition

• 90 days from entry of judgment — Supreme Court Rule 13.1.
• Not from the mandate. Rule 13.3: the time “runs from the date of entry of the judgment or order sought to be reviewed, and not from the issuance date of the mandate.”
• A Justice may extend the time for good cause, but “for a period not exceeding 60 days” — Rule 13.5.
• Rule 10 states the criteria, and they are about conflicts and national importance — not about whether the decision below was wrong.
• Rule 10 warns expressly: review “is rarely granted when the asserted error consists of erroneous factual findings or the misapplication of a properly stated rule of law.”
• The Rules were revised effective March 16, 2026 — including a paper-copy requirement that can render an e-filed petition untimely.
• A cert denial is not a ruling on the merits, and the § 2255 clock is running while the petition is pending.

Rule 10, the real odds, and the § 2255 clock

This is the table to read before deciding whether to file.

The question	The answer	The source
Is review available as of right?	No. “Review on a writ of certiorari is not a matter of right, but of judicial discretion. A petition for a writ of certiorari will be granted only for compelling reasons.”	Sup. Ct. R. 10
What counts as compelling — conflict between circuits	“a United States court of appeals has entered a decision in conflict with the decision of another United States court of appeals on the same important matter”	Rule 10(a)
— departure from usual proceedings	a court of appeals “has so far departed from the accepted and usual course of judicial proceedings, or sanctioned such a departure by a lower court, as to call for an exercise of this Court’s supervisory power”	Rule 10(a)
— unsettled important federal question	a court “has decided an important question of federal law that has not been, but should be, settled by this Court”	Rule 10(c)
— conflict with Supreme Court precedent	a court “has decided an important federal question in a way that conflicts with relevant decisions of this Court”	Rule 10(c)
What is NOT enough	“A petition for a writ of certiorari is rarely granted when the asserted error consists of erroneous factual findings or the misapplication of a properly stated rule of law.”	Rule 10, closing sentence
Deadline	“within 90 days after entry of the judgment”	Rule 13.1
Runs from	“the date of entry of the judgment or order sought to be reviewed, and not from the issuance date of the mandate”	Rule 13.3
Extension	“For good cause, a Justice may extend the time to file a petition for a writ of certiorari for a period not exceeding 60 days.”	Rule 13.5
Cases on the docket, OT2022	4,882 (1,529 paid; 3,349 in forma pauperis)	AO Table A-1
Cases granted plenary review, OT2022	61	AO Table A-1
Cases argued, OT2022	68	AO Table A-1
The § 2255 trap	A cert denial is not a merits ruling, and the one-year § 2255 clock generally runs from when the judgment becomes final — which depends on whether a petition was filed and when it was resolved	28 U.S.C. § 2255(f)

Set the two numbers side by side: 61 plenary grants out of 4,882 cases on the docket in October Term 2022. That is roughly one in eighty, and the odds are materially worse for in forma pauperis petitions, which made up 3,349 of that docket. No page should tell you your case is likely to be taken.

Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: The most useful question before filing is not “was the panel wrong?” It is “what would this Court be fixing for the country?” Rule 10 is not a merits standard, and a petition written as a third merits brief — however correct — is asking the Court to do something it has told you it does not do. If the answer to the national question is “nothing,” the honest advice is to spend the effort on the § 2255 instead.

What certiorari actually is

Certiorari is a discretionary writ. The Supreme Court’s jurisdiction over federal court of appeals decisions comes from 28 U.S.C. § 1254, which provides that cases in the courts of appeals may be reviewed “[b]y writ of certiorari granted upon the petition of any party to any civil or criminal case, before or after rendition of judgment or decree.”

The timing rule has a statutory as well as a rules basis: 28 U.S.C. § 2101(c) governs the time for applying for certiorari and is the statutory backstop to Rule 13.

What follows from “discretionary”:

• There is no right to Supreme Court review. The court of appeals is, for practical purposes, the last court that will examine your case closely.
• The Court is not error-correcting. It takes cases to settle federal law, not to fix individual injustices — which is why Rule 10’s closing sentence exists.
• Denial explains nothing. A denial of certiorari is not a decision that the court of appeals was right. It carries no precedential weight and reflects no view on the merits.

The 90-day deadline, and the mistake that costs it

The deadline is 90 days from entry of judgment. Rule 13.1: “Unless otherwise provided by law, a petition for a writ of certiorari to review a judgment in any case, civil or criminal, entered by a state court of last resort or a United States court of appeals (including the United States Court of Appeals for the Armed Forces) is timely when it is filed with the Clerk of this Court within 90 days after entry of the judgment.”

It does not run from the mandate. Rule 13.3 is explicit: “The time to file a petition for a writ of certiorari runs from the date of entry of the judgment or order sought to be reviewed, and not from the issuance date of the mandate (or its equivalent under local practice).”

That single sentence is the most commonly missed fact about certiorari timing. The mandate issues weeks after the decision — 7 days after the rehearing window closes under Fed. R. App. P. 41(b) — so a defendant counting 90 days from the mandate is counting from a date roughly three weeks too late, and files roughly three weeks late.

Rehearing changes the trigger; the mandate does not. If a timely petition for rehearing is filed and denied, the 90 days runs from the denial of rehearing rather than from the original judgment.

Extensions are available but bounded. Rule 13.5: “For good cause, a Justice may extend the time to file a petition for a writ of certiorari for a period not exceeding 60 days.” An application for an extension must be made well before the deadline; it is not a formality, and the Court’s guidance discourages last-minute requests.

New for 2026: the e-filing paper-copy trap

The Supreme Court’s Rules were revised effective March 16, 2026, and one change directly threatens timeliness. Almost nothing on the open web has caught up with it yet.

Amended Rule 29.2 provides that a document is timely filed if it is received by the Clerk in paper form within the time for filing; or sent by first-class mail with a qualifying postmark; or delivered to a third-party commercial carrier for delivery within three calendar days; or “properly submitted to the Court’s electronic filing system on or before the last day for filing.” Then the new sentence:

“For a document submitted to the Court’s electronic filing system, required paper copies of the filing must be delivered or mailed to the Clerk through one of the methods in subsections (1)-(3) above within three days of the electronic submission.”

The Clerk’s Comment accompanying the revision states the purpose plainly:

“The change to Rule 29.2 is designed to avoid a situation where a filer incorrectly believes that submission of a document through the Court’s electronic filing system constitutes a timely filing, thereby rendering the filing untimely and, in the case of a cert petition in a civil action, depriving the Court of jurisdiction to consider the petition.”

The practical instruction: e-filing alone does not complete the filing. The required paper copies must follow within three days by one of the specified methods. Diary the paper-copy date at the same time as the filing date.

Two other 2026 changes affect petition content. Rule 14.1(b)(i) now requires the list of parties to include “their respective stock ticker symbols, if any,” and Rule 29.6’s corporate disclosure statement requires the same — both to support the Court’s electronic conflict-checking system. These matter mainly in white-collar cases with corporate parties.

What actually gets a case granted

Rule 10 lists the considerations, and they describe four real-world scenarios.

1. A circuit split. The most common successful ground. Rule 10(a): a court of appeals “has entered a decision in conflict with the decision of another United States court of appeals on the same important matter.” A petition on this ground must document the conflict precisely — which circuits, which cases, on what question — and explain why it is genuine rather than a difference in facts or phrasing. This is why a rehearing en banc petition documenting the conflict is a natural predecessor; Rule 40(b)(2)(C) uses closely parallel language. See petition for rehearing and federal appeals court.

2. An important unsettled federal question. Rule 10(c): a court “has decided an important question of federal law that has not been, but should be, settled by this Court.” The emphasis is on important and should be settled — a recurring question that affects many cases, not one that happens to be unresolved.

3. Conflict with Supreme Court precedent. Rule 10(c), second clause: a court “has decided an important federal question in a way that conflicts with relevant decisions of this Court.”

4. A serious departure from the usual course. Rule 10(a)’s supervisory-power clause, invoked rarely.

And the sentence that disposes of most petitions: “A petition for a writ of certiorari is rarely granted when the asserted error consists of erroneous factual findings or the misapplication of a properly stated rule of law.” Most criminal appellants’ complaint is precisely that the court of appeals misapplied a correctly stated rule to their facts. Rule 10 says, in terms, that this is not a reason for review.

What a certiorari petition must contain

The petition’s contents are prescribed in detail by Supreme Court Rule 14.1, which requires nine components “in the order indicated.”

Rule 14.1	What it requires
(a) Questions presented	“expressed concisely in relation to the circumstances of the case, without unnecessary detail. The questions should be short and should not be argumentative or repetitive.” They “shall be set out on the first page following the cover, and no other information may appear on that page.” In a capital case, “the notation ‘capital case’ shall precede the questions presented.”
(b) Parties, corporate disclosure, related proceedings	All parties below “along with their respective stock ticker symbols, if any” (new in 2026); a Rule 29.6 corporate disclosure statement; and a list of all directly related proceedings
(c) Tables	A table of contents and table of cited authorities, if the petition exceeds 1,500 words
(d) Citations	Official and unofficial reports of the opinions and orders below
(e) Jurisdictional statement	Including “the date the judgment or order sought to be reviewed was entered” and “the date of any order respecting rehearing, and the date and terms of any order granting an extension of time”
(f) Provisions involved	Constitutional provisions, statutes, and regulations “set out verbatim with appropriate citation”
(g) Statement of the case	“A concise statement of the case setting out the facts material to consideration of the questions presented”
(h) Argument	“A direct and concise argument amplifying the reasons relied on for allowance of the writ. See Rule 10.”
(i) Appendix	The opinions and orders below, any order on rehearing, the judgment, and other essential material

Three features of that list are worth drawing out.

The questions presented carry unusual weight. Rule 14.1(a) provides that “[t]he statement of any question presented is deemed to comprise every subsidiary question fairly included therein,” and — critically — “[o]nly the questions set out in the petition, or fairly included therein, will be considered by the Court.” A question drafted too narrowly forecloses arguments; drafted argumentatively, it signals inexperience on the first page the Justices’ clerks read.

No separate supporting brief is allowed. Rule 14.2: “All contentions in support of a petition for a writ of certiorari shall be set out in the body of the petition … No separate brief in support of a petition for a writ of certiorari may be filed, and the Clerk will not file any petition for a writ of certiorari to which any supporting brief is annexed or appended.”

Rule 14.1(h) points at Rule 10. The argument section is described as “amplifying the reasons relied on for allowance of the writ” — reasons for the writ, not reasons the decision below was wrong. The rule’s own cross-reference is the clearest available signal about what the petition should argue.

The Clerk enforces form, with a grace period. Rule 14.5: “If the Clerk determines that a petition submitted timely and in good faith is in a form that does not comply with this Rule or with Rule 33 or Rule 34, the Clerk will return it with a letter indicating the deficiency. A corrected petition submitted in accordance with Rule 29.2 no more than 60 days after the date of the Clerk’s letter will be deemed timely.” A form defect in a timely, good-faith petition is fixable. A late petition is not.

Rule 14.4 supplies the closing warning: “The failure of a petitioner to present with accuracy, brevity, and clarity whatever is essential to ready and adequate understanding of the points requiring consideration is sufficient reason for the Court to deny a petition.”

What happens after you file

The sequence is set by Rule 15, and knowing it prevents a good deal of anxious waiting.

Step	What happens	Timing
Docketing	The Clerk dockets the petition and assigns a number	On receipt
Brief in opposition	Optional for the respondent — “not mandatory except in a capital case … or when requested by the Court”	Within 30 days after docketing (Rule 15.3)
Waiver	The respondent may instead file an express waiver of the right to respond	Any time
Reply brief	The petitioner “may file a reply brief addressed to new points raised in the brief in opposition”	Before distribution
Distribution	The Clerk distributes to the Justices on waiver, on expiry of the response time, or “no less than 14 days after the brief in opposition is filed”	Rule 15.5
Conference	The petition is considered at a Justices’ conference	Weeks after distribution
Order	Grant, deny, GVR, or relist for a later conference	On an order list

Two signals are worth reading.

A call for a response is meaningful. The government frequently waives the right to respond in routine criminal petitions. If the Court requests a response in a case where the respondent had waived, that is one of the few observable indications that at least one chambers is interested.

Relisting is meaningful. A petition carried over to a later conference rather than denied outright may indicate a dissent from denial is being written, a summary reversal is under consideration, or the case is being held for another. It is not a guarantee of anything, but it is not nothing.

Rule 15.8 also permits a supplemental brief “at any time while a petition for a writ of certiorari is pending, calling attention to new cases, new legislation, or other intervening matter not available at the time of the party’s last filing” — the mechanism by which a petitioner flags a newly decided case that supports a GVR.

Length and format

The petition is a booklet-format document with strict limits. Under Rule 33.1, booklet documents must comply with the word limits in the rule’s chart, and those limits “do not include the questions presented, the list of parties and the corporate disclosure statement, the table of contents, the table of cited authorities, the listing of counsel at the end of the document, or any appendix,” but they “include footnotes.” A reply to a brief in opposition is capped at 3,000 words.

Exceeding the limits requires leave, and the rule discourages asking: “For good cause, the Court or a Justice may grant leave to file a document in excess of the word limits, but application for such leave is not favored,” and any such application “must be received by the Clerk at least 15 days before the filing date of the document in question, except in the most extraordinary circumstances.”

Forty copies of a booklet-format document must be filed. A petitioner proceeding in forma pauperis under Rule 39 files under the relaxed requirements of Rule 33.2 instead — which is the practical reason most incarcerated petitioners proceed IFP regardless of the fee.

The rule of four

The Court’s internal practice is that four Justices must vote to grant a petition, even though five are needed to win on the merits. The rule of four is a longstanding convention rather than a published rule, and its practical effect is to make grants somewhat more available than a majority requirement would — a minority of the Court can force the case onto the docket.

Petitions are circulated to the Justices’ chambers, most are considered through the “cert pool” in which participating chambers share a single clerk’s memorandum, and cases are discussed at conference. The vast majority are denied without discussion — they never reach the discuss list at all.

Two practical implications follow for a petitioner. The first reader of your petition is a law clerk writing a memorandum for several chambers at once, under time pressure, across a very large volume of petitions. Whatever makes the case cert-worthy has to be visible on the questions presented and in the opening pages, not developed over twenty.

The second is that the rule of four cuts both ways. A single sympathetic chambers cannot grant, but it can flag a case for discussion, which is why a petition documenting a genuine and acknowledged conflict has a real path even from an unrepresented petitioner.

In forma pauperis petitions

A petitioner who cannot afford the filing fee and printing costs may proceed in forma pauperis, which also relaxes the booklet-format requirements. The Court publishes a Guide to Filing In Forma Pauperis Cases (March 2026) alongside the current rules.

Two realities should be stated plainly.

IFP petitions are the majority of the docket and the minority of the grants. In October Term 2022, 3,349 of the 4,882 cases on the docket were in forma pauperis, against 1,529 paid cases (AO Table A-1). Plenary grants that term totaled 61.

The Clerk still enforces the rules. Rule 39 provides that “[w]hile making due allowance for any case presented under this Rule by a person appearing pro se, the Clerk will not file any document if it does not comply with the substance of these Rules or is jurisdictionally out of time.” Allowance is made for form; it is not made for the deadline.

GVR orders: the disposition most defendants have never heard of

There is a fourth possible outcome besides grant, deny, and summary reversal, and for a federal prisoner it can be the most valuable of all.

A GVR — grant, vacate, and remand — is an order in which the Court grants certiorari, vacates the judgment below, and remands to the court of appeals for further consideration in light of an intervening decision, a confession of error by the Solicitor General, or a change in the governing law.

Why it matters:

• It is far more common than a plenary grant. The Court disposes of many petitions this way when a recent decision may affect the outcome below.
• It does not require your case to be the vehicle. If the Court decides a question in someone else’s case, pending petitions raising the same issue are candidates for a GVR.
• It is a reason to keep a petition pending. A petition filed and held while a related case is decided can produce relief that would be unavailable to someone whose judgment became final.

That last point is the strategic argument for filing a petition that will probably be denied: if a relevant question is pending before the Court, a live petition preserves the possibility of a GVR, while a final judgment does not.

The § 2255 trap: your clock is running

This is the practical warning the page exists to deliver.

A cert denial is not a ruling on the merits and it resolves nothing about your case. What it does do is fix the date your conviction becomes final — and the one-year period for a motion under 28 U.S.C. § 2255 generally runs from that date.

The interaction, stated carefully:

• If you file a certiorari petition, the judgment generally becomes final when the Court denies the petition (or decides the case).
• If you do not file one, finality generally arrives when the time for filing expires — which is 90 days after entry of the court of appeals’ judgment, under Rule 13.1.
• Either way, the § 2255 year then runs. Filing a petition postpones the start; it does not create extra time afterward.

Two errors follow from misunderstanding this. The first is assuming that a pending cert petition somehow stops all clocks and that § 2255 work can wait — the year is coming either way, and the preparation of a § 2255 motion takes months. The second is calculating finality from the mandate, which is the same mistake that costs the cert deadline.

The consequence of getting the date wrong is total: an untimely § 2255 motion is generally barred regardless of its merits.

The practical instruction is to prepare the § 2255 motion while the certiorari petition is pending, not after it is denied. See direct appeal vs 2255, post-conviction deadlines, and the 2255 deadline calculator.

Applied Insight — Christopher Zoukis, JD, MBA, Managing Director: The conversation to have when a court of appeals affirms is not “should we go to the Supreme Court.” It is “what is the finality date under each option, and what are we doing with the year that follows.” A cert petition and a § 2255 motion are not alternatives on a timeline — the first sets the start date for the second, and the work on the second should already be underway.

When a certiorari petition is worth filing — and when it is not

Worth filing when:

• There is a documented circuit conflict on the question, ideally one the court of appeals or a dissent acknowledged
• The question is recurring and consequential beyond your case
• A relevant issue is already pending before the Court, making a GVR realistically possible
• The court of appeals departed from settled Supreme Court precedent in an identifiable way
• The Solicitor General has confessed error, or the government’s position has shifted

Usually not worth filing when:

• The complaint is that the court of appeals applied a correctly stated rule incorrectly to your facts — Rule 10 addresses this directly
• The issue is fact-bound and would not affect any other case
• The decision below was unpublished and creates no conflict
• The remaining effort and money would do more good on a § 2255 motion

A caveat on the second list. Even a petition unlikely to be granted preserves the GVR possibility and postpones finality. Where the § 2255 claims need time to develop — obtaining transcripts, securing declarations from trial counsel, locating witnesses — the additional months a pending petition provides can have real value. That is a legitimate reason to file, and it should be a deliberate decision rather than a default in either direction. For getting the underlying materials, see getting transcripts, PSR and your file.
