A federal appeal takes a median of 9.7 months from the filing of the notice of appeal to a final decision, based on U.S. Courts data for the twelve-month period ending September 30, 2024. That is the middle of a wide range: the fastest federal circuit resolved appeals in a median of 5.1 months, while the slowest took 13.5 months.1U.S. Courts. U.S. Courts of Appeals – Median Time Intervals in Months for Civil and Criminal Appeals Terminated on the Merits, by Circuit So the honest answer to how long it takes for an appellate court to decide is: usually somewhere between six months and a year and a half, driven by which court hears the case, how complex the record is, and how long briefing and deliberation actually run.
Civil appeals decided on the merits ran slightly longer than the overall median, at 11.5 months. Criminal appeals came in at 10.8 months. If you measure from the day the original lawsuit was filed in the trial court all the way through the appellate ruling, the median stretches to 33.4 months nationally, and past 41 months in the Third Circuit.2U.S. Courts.

State appellate courts don’t report their statistics as uniformly, and the spread is wider. Some state intermediate appellate courts resolve cases in around six months. Others take well over a year. State supreme courts, which usually pick their own cases and hear fewer of them, tend to take longer once they agree to hear a case.
What Is Happening During the Wait
An appeal is not one long pause. It moves through phases, and knowing which phase your case is in is the best way to estimate the months still ahead.
Filing the Notice of Appeal
The clock starts when the losing party files a notice of appeal with the trial court. In federal civil cases the deadline is 30 days from the final judgment, or 60 days if the federal government is a party. In federal criminal cases a defendant has 14 days.3Legal Information Institute, Cornell Law School. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right—When Taken Most state deadlines fall in the 30-to-60-day range. Miss it and the appeal almost always ends before it begins.
Assembling the Record
Before anyone writes a brief, the trial record has to be compiled and transmitted to the appellate court: transcripts, exhibits, and the relevant filings. The appellant must order the transcript from the court reporter within 14 days of filing the notice. Federal local rules commonly allow the reporter 30 to 60 days to produce it, depending on length and case type, and extensions are common when a trial ran long. This is one of the least visible sources of delay. A complex trial with weeks of testimony can generate thousands of transcript pages, and court reporters are usually working several cases at once.
Briefing
Briefing is the heart of the appeal. The appellant’s opening brief is due within 40 days after the record is filed. The appellee has 30 days to respond. The appellant can file a reply within 21 days after that.4Cornell Law Institute. Federal Rules of Appellate Procedure Rule 31 – Serving and Filing Briefs Even without extensions, briefing alone eats about three months. Extensions happen constantly. Attorneys juggling other cases or working through a dense record routinely ask for more time, and courts routinely grant it.
Oral Argument or Submission on the Briefs
Once briefing closes, the panel either schedules oral argument or takes the case on the written briefs alone. A unanimous three-judge panel can skip argument if the appeal is frivolous, the issues have already been authoritatively decided, or the briefs adequately present the facts and law.5Legal Information Institute, Cornell Law School. Federal Rules of Appellate Procedure Rule 34 – Oral Argument When argument is granted, it is typically scheduled about three months after the final brief. Each side usually gets 15 minutes. No witnesses, no new evidence. Appeals decided on the briefs alone often move faster.
Deliberation and the Opinion
After argument or submission, the case is “under advisement.” The judges meet, vote, and assign one judge to write the opinion. A dissenting judge may write separately, and a judge agreeing with the result on different reasoning may write a concurrence. Every additional opinion adds drafting and editing time.
This is the hardest phase to predict. A straightforward case with a unanimous panel can produce an opinion in a few weeks. A case with novel legal questions and a split panel can take many months. There is no formal deadline for issuing an opinion.
Why the Range Is So Wide
Some factors are built into the system; others depend on your case.
- Case complexity. An appeal turning on a single well-settled legal issue moves faster than one with multiple novel constitutional questions or a record spanning tens of thousands of pages.
- Court backlog. The gap between the fastest and slowest circuits reflects staffing, judicial vacancies, and sheer volume. A court with unfilled seats has longer wait times no matter how simple your case is.
- Disagreement among the judges. A unanimous panel can issue a short opinion quickly. When judges split, the majority has to anticipate and answer the dissent, and the dissenter needs time to write. That back-and-forth can add months.
- Published vs. unpublished opinions. Published opinions set binding precedent and get more scrutiny; they take longer. Unpublished opinions resolve the case without creating precedent, are usually much shorter, and come out sooner. Straightforward appeals tend to draw unpublished decisions.
- Extensions and procedural delays. Briefing extensions, transcript delays, and scheduling conflicts for oral argument each add a little time. They compound.
Can You Speed It Up
You can file a motion to expedite. Courts grant them selectively, and you need a compelling reason: time-sensitive rights such as a child custody dispute with a child’s living situation in limbo, deteriorating health of a party, or a delay that will itself cause irreparable harm. A persuasive motion explains the concrete harm the normal timeline would cause, confirms the case can be decided on the existing record, and shows both sides can meet compressed briefing deadlines. If granted, the court may shorten briefing, prioritize the case for argument, or both.
Another option, if both sides agree, is to submit the case on the briefs without oral argument. That removes the scheduling wait for argument.5Legal Information Institute, Cornell Law School. Federal Rules of Appellate Procedure Rule 34 – Oral Argument Realistically, most appeals proceed on the standard timeline. A motion that amounts to preferring a faster answer will not succeed.
How the Decision Reaches You
Appellate courts don’t announce rulings from the bench. The decision arrives as a written opinion, distributed by the clerk to the attorneys on record or directly to any self-represented party, and simultaneously posted publicly, usually on the court’s website.6Legal Information Institute. Federal Rules of Appellate Procedure Rule 45 – Clerk’s Duties A published opinion establishes binding precedent and typically runs long, with detailed analysis and citations. An unpublished opinion resolves only the dispute in front of the court and can be as short as a few pages.
The Clock After the Decision
The opinion is not quite the final step. The losing party has 14 days to file a petition for rehearing by the same panel or rehearing en banc by the full court. When the federal government is a party, that deadline extends to 45 days.7Legal Information Institute (LII) / Cornell Law School. Federal Rules of Appellate Procedure Rule 40 – Panel Rehearing; En Banc Determination
If no petition is filed, or one is filed and denied, the court issues its mandate seven days later. The mandate is the formal order that returns the case to the trial court and makes the appellate ruling effective. Until it issues, the trial court cannot act on the ruling.8Legal Information Institute (LII) / Cornell Law School. Federal Rules of Appellate Procedure Rule 41 – Mandate: Contents; Issuance and Effective Date; Stay
Beyond rehearing, the losing party can petition the U.S. Supreme Court for review within 90 days of the appellate judgment. The Supreme Court accepts fewer than two percent of petitions, so for almost all cases the appellate ruling is the end.9Cornell Law School.

One Thing to Know While You Wait
Filing an appeal does not automatically pause the trial court’s judgment. If you lost a money judgment, the other side can begin collection while the appeal is pending unless you ask the trial court to stay the judgment, usually by posting a supersedeas bond for the judgment amount plus interest and costs.10Cornell University Legal Information Institute (LII). Federal Rules of Appellate Procedure Rule 8 – Stay or Injunction Pending Appeal The wait for a decision and the enforceability of the underlying judgment are separate clocks, and confusing them is expensive.
