Yes, you can appeal a jury verdict, but an appeal is not a second trial. The appellate court will not rehear witnesses, reweigh evidence, or reconsider whom the jury believed. It reviews the record for a specific legal error serious enough to have changed the outcome. Reversal is the exception: in federal civil cases, reversal rates typically run between 6 and 15 percent depending on the circuit, so most verdicts stand.
Who Can Appeal
Your right to appeal depends on which side of the case you sat on and whether it was criminal or civil. A convicted criminal defendant has a constitutional right to appeal, and if they cannot afford a lawyer, the court must appoint one for the first appeal.1Justia Law. Douglas v. California, 372 U.S. 353 (1963) In a civil case, either side can appeal an unfavorable verdict, but there is no right to a free appellate lawyer.
One boundary matters before anything else. If a jury acquits a criminal defendant, the prosecution cannot appeal the verdict. The Double Jeopardy Clause of the Fifth Amendment makes a jury acquittal final, a rule the Supreme Court settled more than a century ago.2Legal Information Institute. Reprosecution After Acquittal The government can appeal certain pretrial rulings or sentences, but not an acquittal itself. A convicted defendant faces no equivalent bar.
What Counts as a Valid Ground
Disagreeing with the jury is not a ground. Appellate courts want to know whether the trial judge got the law wrong in a way that mattered.
The most common ground is legal error by the trial judge. This includes instructing the jury incorrectly on the law, admitting evidence that should have been excluded, keeping out evidence the jury should have heard, or misapplying a legal standard. These errors have to be preserved: your attorney generally needed to object when the error occurred. Issues raised for the first time on appeal are almost always rejected.
Juror misconduct is a second ground. If a juror researched the case online, visited a location central to the dispute, or had unauthorized contact with a party or lawyer, the verdict may not reflect what happened in the courtroom. Proving misconduct is hard because courts are reluctant to probe deliberations, but strong evidence can invalidate the result.
The third ground is legal insufficiency of the evidence, and it is the hardest to win. You have to show that even viewing all the evidence in the light most favorable to the winning side, no reasonable jury could have reached the verdict. The claim is not that the evidence was weak. It is that the evidence was essentially nonexistent on a required element.
Why Many Appeals Fail Even When Errors Happened
Two rules quietly decide most appeals before the merits are ever reached.
The first is the harmless error rule. Federal law tells appellate courts to disregard errors that do not affect the substantial rights of the parties.3Office of the Law Revision Counsel. 28 USC 2111 – Harmless Error You must show not only that a mistake happened but that it likely changed the outcome. A judge who admitted one improper piece of evidence in a case with overwhelming proof on the same point probably committed a harmless error. This is where many appeals die.
The second is the standard of review, which sets how much deference the appellate court gives the trial judge. It varies by issue:
- Legal questions are reviewed de novo. The appellate court decides the question fresh, with no deference to the trial judge. This is the friendliest standard for an appellant.
- Most evidentiary and procedural rulings are reviewed for abuse of discretion. The court asks whether the ruling was so far outside reasonable judgment that no fair-minded judge would have made it. Simply disagreeing is not enough.4Legal Information Institute. Abuse of Discretion
- Jury findings of fact get the most protection. The court asks only whether substantial evidence supports the jury’s conclusion, viewing the record favorably toward the verdict winner. Overturning factual findings is deliberately difficult.
A purely legal question reviewed de novo gives you a real shot. A challenge to a close evidentiary call is a long climb.
The Steps You Have to Follow
Post-Trial Motions First
Before filing an appeal, the losing party typically files post-trial motions with the trial judge. These motions preserve issues and give the trial court a chance to correct its own mistakes.
A Motion for a New Trial argues that a legal error prevented a fair outcome. In federal civil cases, it must be filed within 28 days after judgment is entered.5Legal Information Institute. Federal Rule of Civil Procedure 59 – New Trial; Altering or Amending a Judgment In federal criminal cases, a defendant may move for a new trial if the interest of justice requires it.6Legal Information Institute. Federal Rules of Criminal Procedure Rule 33 – New Trial
A Renewed Motion for Judgment as a Matter of Law asks the judge to override the verdict because the evidence was legally insufficient. There is a trap: you can only file this after trial if your attorney made a similar motion before the case went to the jury. If that earlier motion was never made, the issue is waived.7Legal Information Institute. Federal Rules of Civil Procedure Rule 50
Filing the Notice of Appeal
Once post-trial motions are resolved, the clock starts on the Notice of Appeal. Miss the deadline and you lose the right to appeal.
In federal court, the civil deadline is 30 days after final judgment is entered. When the federal government is a party, both sides get 60 days. Criminal defendants have just 14 days.8Legal Information Institute. Rule 4 – Appeal as of Right, When Taken State court deadlines vary but are equally strict. Certain post-trial motions can pause the appeal clock, but the rules about which ones qualify are technical, and getting them wrong is one of the most common ways people forfeit an appeal.
Federal appellate courts also generally hear appeals only from “final decisions” of the district courts, meaning decisions that resolve all claims against all parties.9GovInfo. 28 USC 1291 – Final Decisions of District Courts Trying to appeal before the case is fully resolved below is not usually permitted.
Briefs and Oral Argument
The appeal is decided mostly on paper. The appellant files an opening brief identifying the legal errors and arguing for reversal. The appellee files a brief defending the trial court’s rulings. The appellant may file a shorter reply. Appellate judges were not in the courtroom, so the record on appeal and these briefs are their only window into what happened.
Some cases also get oral argument, where lawyers for each side appear before a panel of judges (usually three) and answer questions under a tight time limit.10Legal Information Institute. Federal Rules of Appellate Procedure Rule 34 – Oral Argument Many appeals are decided on the briefs alone.
Protecting Yourself While the Appeal Is Pending
Filing an appeal does not automatically stop the winning side from collecting on a money judgment. In federal civil cases, enforcement is automatically paused for only 30 days after judgment is entered.11Legal Information Institute. Rule 62 – Stay of Proceedings to Enforce a Judgment After that, the judgment creditor can start seizing assets or garnishing wages unless you obtain a stay.
The standard way to get a longer stay is to post a supersedeas bond, a guarantee backed by a surety or cash deposit that the judgment will be paid if the appeal fails. The bond usually covers the full judgment plus anticipated interest and costs, though courts have some flexibility on the amount. If you cannot afford a bond on a large judgment, you can ask the court for an alternative, but it is not obligated to grant one. Going without a stay is risky: the other side can enforce the judgment immediately, and winning on appeal after your assets are gone creates a messy recovery problem.
What the Court Can Do
The appellate court issues a written opinion with one of three results. It can affirm, meaning it finds no error or only harmless error. Affirmance is by far the most common outcome. It can reverse, concluding a legal error materially affected the outcome, which may end the case in the appellant’s favor. Or it can remand, sending the case back with instructions, which might mean a new trial, reconsideration of a specific ruling, or a recalculation of damages. Reversal and remand often go together.
If You Lose the Appeal
Two further layers of review exist, and both are hard to reach.
You can petition for en banc rehearing, asking the full court of appeals rather than the original three-judge panel to reconsider. En banc review is not favored and is ordinarily granted only when the panel’s decision conflicts with prior decisions of that court or the case involves a question of exceptional importance.12Office of the Law Revision Counsel. Federal Rules of Appellate Procedure Rule 35 – En Banc Determination Most petitions are denied.
You can also petition the U.S. Supreme Court for certiorari within 90 days of the appellate court’s judgment.13Legal Information Institute. Supreme Court Rule 13 – Review on Certiorari, Time for Petitioning The Court accepts fewer than 2 percent of cases it is asked to hear. Realistically, a certiorari petition is worth pursuing only when the case involves a split between federal circuits or a major unresolved constitutional question.
What It Costs and How Long It Takes
Appeals are expensive and slow. The federal docketing fee alone is $605.14United States Courts. Court of Appeals Miscellaneous Fee Schedule That fee is modest next to the cost of preparing trial transcripts, which court reporters typically charge by the page, plus attorney fees for research, writing, and argument. A straightforward appeal with competent appellate counsel commonly runs into the tens of thousands of dollars. Complex cases with lengthy records cost far more.
Timing is the other cost. Based on the most recent federal data, the median time from filing a notice of appeal to a final decision on the merits is roughly 10 to 12 months.15United States Courts. Table B-4A – U.S. Courts of Appeals, Median Time Intervals in Months for Civil and Criminal Appeals Terminated on the Merits En banc review or a Supreme Court petition stretches that timeline considerably. Before starting, weigh the money, the wait of at least a year, and the odds. Most jury verdicts survive appeal, and knowing that upfront is part of making a sound decision about whether to file.
