Success hinges on proving significant legal errors, not just disagreement with the outcome, making it a long shot for most appellants.

Do appeals usually win?
No, appeals are generally not very successful, with most sources indicating success rates well below 20% and often in the single digits, though this varies by jurisdiction and case type, as appellate courts uphold trial decisions the majority of the time, but a strong case based on significant legal errors, not just dissatisfaction with the outcome, can improve odds. Winning requires demonstrating substantial legal mistakes that harmed the appellant, not simply disagreeing with the original verdict, and the complexity and cost are significant factors.
Why are appeals so hard to win?
The appellate court doesn't listen to new witnesses or review new evidence. Instead, it relies solely on the trial record.
