Grounds for Appeal: Do You Have a Case?

After an adverse decision, the natural question is, “Can I appeal?” The honest answer is that you almost always can file an appeal — but whether you should is a very different question. An appeal is not a do-over of your case, and disappointment with the result is not, by itself, a ground for appeal. To have a viable appeal, you need something more specific: an error of law or a reviewable error in the proceedings below that may have affected the outcome.

This page explains what actually counts as a ground for appeal in New York, the concepts that quietly decide most appeals — preservation, harmless error, and the standard of review — and how to soberly evaluate whether an appeal is worth pursuing. The deadlines are short and unforgiving, so if you are weighing an appeal, the time to act is now.

An Appeal Requires an Error, Not Just an Unhappy Outcome

The appellate court does not retry your case. It does not hear witnesses, weigh new evidence, or substitute its own judgment for the trial court’s simply because it might have decided things differently. Instead, the court reviews the existing record and asks a narrower question: did the lower court make a legal or procedural error serious enough to change the result?

That distinction is the heart of every appeal. A trial judge who weighed conflicting testimony and believed one side over the other generally did exactly what the law asks of a fact-finder. A judge who applied the wrong legal standard, or who excluded evidence the law required to be admitted, made a reviewable error. The first is the ordinary work of trial courts; the second is what appeals are for. For a fuller walk-through of how the process unfolds, see our overview of the appeals process in New York.

Common Grounds for Appeal

Most successful appeals rest on one or more of the following grounds. Each must be grounded in the record — the appellate court will not consider facts or arguments that were never presented to the trial court.

• Legal error. The trial court misinterpreted or misapplied the law — for example, by using the wrong legal standard, misreading a statute, or applying a rule that does not govern the case. Pure questions of law are the strongest footing for an appeal because they are reviewed without deference to the trial court.
• Errors in admitting or excluding evidence. The court let in evidence that should have been kept out, or excluded evidence that should have been admitted. An evidentiary error is a ground for appeal only if it was significant enough to affect the outcome.
• Incorrect jury instructions. In a jury case, the judge must accurately explain the governing law. A charge that misstates the law, omits a necessary instruction, or misleads the jury can be a strong ground for appeal, because it may have steered the verdict.
• Insufficient evidence or a verdict against the weight of the evidence. A party may argue that no reasonable jury could have reached the verdict on the evidence presented, or that the verdict was so contrary to the weight of the evidence that it should not stand. These arguments face a demanding, deferential standard.
• Abuse of discretion. Many trial rulings — on scheduling, discovery, and the conduct of trial — are committed to the trial judge’s discretion. To win on appeal, you generally must show that the ruling was not merely debatable but an actual abuse of that discretion.
• Procedural errors that affected the outcome. A defect in how the proceedings were conducted can be a ground for appeal, but only where it had a real effect on the result.

Preservation: The Issue Must Have Been Raised Below

Preservation is the single most overlooked concept in appellate practice, and it ends more appeals than people expect. As a general rule, you cannot raise an issue for the first time on appeal. To be reviewable, the issue must have been raised in the trial court — typically by a timely objection, motion, or request — so that the trial judge had a fair chance to address it.

If your attorney did not object when objectionable evidence came in, or did not request a particular jury instruction, the appellate court will often decline to consider that point at all, no matter how strong it might have been. This is why what happens at trial shapes what is possible on appeal, and why an early review of the record matters so much. When we evaluate a case, one of the first things we look for is whether the key issues were properly preserved.

• Objections to evidence generally must be made when the evidence is offered.
• Objections to a jury charge generally must be raised before the jury deliberates.
• Legal arguments must usually have been presented to the trial court in some form to be reviewable.

Harmless Error: Not Every Mistake Leads to Reversal

Even a genuine error is not enough on its own. New York applies the doctrine of harmless error: an appellate court will not reverse a judgment because of a mistake that did not affect the result. The question is not merely whether the trial court erred, but whether the error was significant enough that it probably influenced the outcome.

A small evidentiary slip in a case with overwhelming evidence on the other side will usually be deemed harmless. The same slip in a closely balanced case might be reversible. So a strong appeal pairs a clear error with a credible explanation of why that error mattered — why, without it, the result might well have been different.

Why Challenging the Facts Is an Uphill Fight

Many people want to appeal because they believe the trial court got the facts wrong — believed the wrong witness, drew the wrong inference, or misjudged the evidence. Those appeals are difficult to win, and the reason is the standard of review.

The standard of review is the lens through which the appellate court examines each issue, and it often matters more than the underlying merits.

• Questions of law are reviewed de novo — the appellate court decides them fresh, with no deference to the trial court. This is the most favorable footing for an appellant.
• Findings of fact after a bench trial receive considerable deference and are generally left undisturbed unless they are against the weight of the evidence.
• Jury verdicts are reviewed for whether they are supported by the weight of the evidence, with respect for the jury’s role as fact-finder.
• Discretionary rulings are reviewed only for abuse of discretion, a demanding standard.

The practical lesson is that an appeal built on a clear legal error stands on much firmer ground than one that asks the court to second-guess a factual finding or a discretionary call. A candid look at which standard applies to your issues is essential before you commit to an appeal.

How to Decide Whether to Appeal

Deciding to appeal is a practical judgment, not just a legal one. We encourage prospective clients to weigh three things honestly:

• Probability of success given the standard of review. Do you have a preserved legal error reviewed de novo, or are you asking the court to overturn a factual finding under a deferential standard? The former is a real argument; the latter is an uphill climb. Be realistic: most appeals are affirmed, and reversal rates are generally low.
• What is at stake. A large judgment, a custody determination, or a ruling with lasting consequences may justify an appeal even where the odds are uncertain. A modest dispute may not warrant the effort, whatever the merits.
• Cost and time. An appeal in New York commonly takes 12 to 24 months and involves the cost of producing the record, filing fees, and attorney fees for the research and writing the briefs demand. See our discussion of the cost of an appeal for a realistic picture.

None of this means a meritorious appeal should be abandoned. Clear legal error does get corrected, and a well-grounded appeal can change a life or a fortune. It simply means the decision deserves a sober, candid assessment rather than a reflexive one. Remember, too, that filing the notice of appeal on time is what preserves your right to appeal at all — that deadline is jurisdictional and cannot be extended, so it should never be allowed to pass while you deliberate.

If you have received an adverse decision and want an honest evaluation of whether you have grounds for appeal, do not wait. Appellate deadlines in New York are strict, jurisdictional, and unforgiving — once the notice-of-appeal deadline passes, the right to appeal is usually gone for good.
