How to Appeal a Personal Injury Verdict: Grounds, Timeline, and What to Expect

When Can You Appeal a Personal Injury Verdict?

An appeal is not a second trial. Appellate courts do not re-examine witness credibility or reweigh the evidence the jury heard. Instead, they review whether the trial was conducted correctly under the law.

This is a critical distinction. If you lost simply because the jury did not believe your witness, that is not an appealable issue. But if the judge made incorrect rulings on evidence, gave a flawed jury instruction, or allowed improper argument, those legal errors can form the basis of an appeal.

Common Grounds for Appeal

Incorrect jury instructions. If the judge misstated the law — for example, applying the wrong negligence standard or omitting a required element — the instruction may have led the jury to the wrong result.

Evidentiary errors. Admission of improperly obtained evidence, exclusion of key expert testimony, or allowance of highly prejudicial material that should have been excluded can support reversal.

Insufficient evidence. A party can argue that no reasonable jury could have reached the verdict on the evidence presented. This is a high bar.

Juror misconduct. Undisclosed conflicts of interest, improper communications, or independent research by jurors can support a new trial motion.

Excessive or inadequate damages. Courts can reduce (remittitur) or increase (additur, permitted in fewer states) a damages award that is grossly out of proportion to the evidence.

The Appeals Timeline

After a verdict, you typically have 30 days to file a notice of appeal, though this varies by jurisdiction. The full appellate brief process — including transcripts, written briefs, and potentially oral argument — can take 12 to 24 months in most states, and longer in federal court.

During the appeal, judgment enforcement may be stayed if you post a supersedeas bond.

Realistic Outcomes

Appellate courts affirm trial verdicts in a large majority of civil cases. Reversal requires demonstrating that a legal error affected the outcome — not just that an error occurred. If reversal is granted, the result is usually a remand for a new trial, not an automatic win.

Speak with an appellate specialist, not just your trial attorney, to evaluate whether an appeal is worth the time and expense.
