Petition for Rehearing vs. Petition for Certiorari: Two Different Tools

After an adverse decision from the Utah Court of Appeals, litigants frequently ask the same question in two different ways: “Can I ask the court to reconsider?” and “Can I take this to the Supreme Court?” These sound similar, but they describe two procedurally and substantively distinct mechanisms — a petition for rehearing and a petition for writ of certiorari — and confusing them, or pursuing the wrong one, can cost a litigant the right to meaningful review entirely.

This post lays out the distinction clearly, including how the two interact procedurally.

The Core Distinction

A petition for rehearing asks the same court — the Court of Appeals panel that issued the decision — to reconsider a specific point of law or fact that it “overlooked or misapprehended.” It stays within the same court and the same panel.

A petition for writ of certiorari asks a different court — the Utah Supreme Court — to take the case for review, based on the broader, forward-looking significance of the legal question presented, not based on whether the Court of Appeals overlooked something.

These differences cascade through every aspect of the two mechanisms: who decides them, what standard governs, what they can accomplish, and how urgently they must be filed.

Petition for Rehearing: URAP Rule 35

URAP Rule 35(a)(1) limits a rehearing petition to cases “in which the court issues an opinion, memorandum decision, per curiam decision, or order resolving the appeal on the merits,” and the petition may only seek to “alter a decision in a manner that affects the substantive rights of the parties or any mandate or rule of law established by the decision.”

Deadline: 14 days after the decision is issued — significantly shorter than the certiorari deadline, and easy to miss if a litigant is still deciding strategy.

Standard: Under Rule 35(a)(3), the petition “must succinctly state and explain the points of law or fact that the petitioner claims the court has overlooked or misapprehended.” This is narrow. It is not an invitation to reargue the case or present new theories — it targets specific, identifiable oversights in the court’s existing reasoning.

Length: Capped at 15 pages, same as a certiorari petition under the current rules.

Response: Critically, under Rule 35(a)(4), no response will be received from the opposing party unless the court itself requests one — and the petition cannot be granted, even in part, without the court having requested a response first. This means the opposing party generally does not need to do anything in reaction to a rehearing petition unless the court signals it is taking the petition seriously enough to want input.

Outcome: The court may deny the petition outright, grant it and modify the decision, or restore the case to the calendar for reargument — though oral argument on a rehearing petition is rare in practice.

A hard limit: Utah Supreme Court standing orders instruct the clerk to refuse successive or untimely rehearing petitions. You get one shot, and it must be timely.

Petition for Writ of Certiorari: URAP Rule 49

A certiorari petition operates on an entirely different logic, discussed fully in What Is a Writ of Certiorari? and The Standard for Granting Certiorari in Utah. In brief:

Deadline: 30 days after the Court of Appeals’ final decision — covered in detail in The 30-Day Clock.

Standard: Governed by URAP Rule 46 — special and important reasons, primarily precedential value, not error correction.

Decision-maker: A different court — the Utah Supreme Court — not the panel that issued the original decision.

Outcome: If granted, the case proceeds to full merits review at the Supreme Court level, a substantially larger undertaking than a rehearing petition’s relatively contained scope.

How They Interact: The Tolling Effect

This is the single most important procedural interaction to understand. Under URAP Rule 48(c), if a timely petition for rehearing is filed by any party, the 30-day certiorari deadline for all parties does not begin running until the rehearing petition is resolved — either denied, or until a subsequent decision is issued on rehearing.

This creates a genuinely useful sequencing option: a party uncertain whether the Court of Appeals’ decision contains a specific, correctable oversight — as opposed to a broader legal-significance problem appropriate for certiorari — can file a rehearing petition first. If granted, the problem may be solved without ever needing to petition the Supreme Court. If denied, the certiorari clock has not been wasted; it begins fresh from the denial date, preserving the full 30 days to develop and file a complete certiorari petition.

The risk in the other direction: a litigant who skips rehearing and goes straight to certiorari forecloses the rehearing option entirely. Once a notice of appeal effectively concludes Court of Appeals proceedings via a certiorari filing, that panel will not revisit its own decision.

Choosing the Right Tool: A Decision Framework

File a petition for rehearing when:

• The Court of Appeals’ decision contains a specific factual or legal point you believe the panel genuinely overlooked or misunderstood
• The error, if corrected, would likely change the outcome without requiring Supreme Court involvement
• You want to preserve the possibility of certiorari review while giving the Court of Appeals a first chance to self-correct
• The issue is case-specific rather than broadly significant to future litigants

File a petition for certiorari (with or without first seeking rehearing) when:

• The legal question is genuinely significant beyond this case — touching statutory interpretation, first-impression issues, or conflicting Court of Appeals precedent
• The Court of Appeals’ reasoning, even if internally consistent, reflects a legal standard you believe the Supreme Court should revisit
• A correction at the rehearing level is unlikely because the issue is not a discrete oversight but a considered legal conclusion the panel is unlikely to abandon on its own

Consider filing both, sequentially:

• When you are unsure which category your case falls into, filing rehearing first preserves the certiorari window while testing whether the Court of Appeals will self-correct — at essentially no cost to your certiorari timeline, provided the rehearing petition itself is timely filed.

A Common and Costly Mistake

Litigants — and sometimes counsel unfamiliar with Utah’s specific procedural architecture — sometimes treat a rehearing petition as a lesser, lower-stakes version of a certiorari petition, filing one as a formality before moving on to “the real appeal” at the Supreme Court. This misunderstands the relationship between the two. A rehearing petition is not a stepping stone to certiorari; it is a separate, narrower remedy aimed at a different kind of problem. Filing a rehearing petition built around generic disagreement with the outcome — rather than a specific, identifiable point the court overlooked — wastes the 14-day window without accomplishing anything, while still (productively, at least) tolling the certiorari clock.

The better practice is to make a deliberate choice based on what the decision actually requires: a narrow correction (rehearing) or a fundamentally different forum’s attention to a significant legal question (certiorari).

KEY RULE

URAP Rules 35 and 48 — Two Distinct Mechanisms

A petition for rehearing under Rule 35 asks the same Court of Appeals panel to correct a specific point of law or fact it overlooked or misapprehended, must be filed within 14 days, and is governed by a narrow correction standard. A petition for certiorari under Rule 49 asks the Utah Supreme Court to take the case based on the Rule 46 precedential-value standard, must be filed within 30 days, and is governed by an entirely different inquiry. A timely rehearing petition tolls the certiorari deadline for all parties under Rule 48(c), making sequential filing — rehearing first, certiorari second if needed — a viable strategy in appropriate cases.

Choosing Your Path After an Adverse Decision

The right choice depends entirely on the specific nature of what went wrong in the Court of Appeals’ decision — a discrete oversight correctable by the same panel, or a legal question significant enough to warrant the Utah Supreme Court’s discretionary attention. Lotus Appellate Law evaluates both pathways for clients facing this decision and frequently coordinates a sequential strategy when appropriate. Contact us promptly after an adverse Court of Appeals decision — the rehearing window is just 14 days.
