What Is an Appeal?
Last updated: March 2026
An appeal is a request for a higher court to review a lower court decision. Appeals are an important part of the legal system, but they are usually not a full do-over of the entire case. Instead, appeals typically focus on whether legal errors affected the outcome.
What is an appeal in a lawsuit?
An appeal is a process in which a party asks a higher court to review a decision made by a trial court. The party seeking review argues that the lower court made an important legal error. In civil litigation, appeals often follow a final judgment, although some types of rulings may be reviewed under specific circumstances before the entire case ends.
Why appeals matter
Appeals matter because they help ensure that legal rules were applied correctly. A trial can involve many rulings about evidence, procedure, jury instructions, motions, and other issues. If a party believes the trial court made a significant mistake, the appellate process may provide a way to challenge that result.
Is an appeal the same as a new trial?
No. An appeal is usually not a complete retrial of the facts. Appellate courts generally review the record created in the trial court rather than hearing the whole case from the beginning again. The focus is often on legal issues, not on starting over with all new witnesses and evidence.
What does an appellate court usually review?
- Legal rulings made by the trial court
- Interpretation of statutes or case law
- Evidentiary rulings
- Jury instructions
- Procedural decisions
- Whether certain errors may have affected the outcome
What is the record on appeal?
Appeals are usually based on the record developed in the lower court. That record may include pleadings, motions, exhibits, transcripts, orders, and the final judgment. Because appellate courts often rely heavily on that existing record, what happened in the trial court remains very important even after trial ends.
What do the parties file in an appeal?
Appeals often involve written briefs in which the parties explain their legal arguments. The appellant, meaning the party challenging the decision, typically files an opening brief. The other side then responds, and further briefing may follow. In some appeals, the court also hears oral argument from the lawyers.
What can happen after an appeal?
An appellate court may affirm the lower court decision, reverse it, modify it, or send the case back for further proceedings. If the matter is remanded, the case may return to the lower court for additional action consistent with the appellate court’s ruling.
Do appeals take time?
Yes. Appeals often add substantial time to the life of a case. Preparing the record, briefing the issues, scheduling oral argument when applicable, and waiting for the appellate court’s decision can all extend the timeline significantly.
Can every court ruling be appealed immediately?
Not always. In many situations, appeals follow a final judgment rather than every intermediate ruling made during the case. There are exceptions in some circumstances, but timing and appealability can be more complicated than many people expect.
Why appeals can be difficult
Appeals are often challenging because the standard of review matters, the arguments are focused on law rather than general fairness, and the appellant usually must show more than simple disagreement with the outcome. The question is often whether a meaningful legal error occurred and whether it mattered.
