What is a CPL 440.10 motion, and when can it actually undo a New York conviction? It’s the request you make when the problem with a conviction isn’t visible in the trial transcript — when the thing that went wrong happened outside the record, where an appeals court would never see it. People usually find their way to it after a direct appeal has already failed, and they’re surprised to learn the door hasn’t necessarily closed.
A CPL 440 Motion Is Not an Appeal
This is the distinction that matters most, and it trips up almost everyone.
A direct appeal asks a higher court to review what’s in the record: the transcript, the exhibits, the rulings the judge made in open court. If the error is visible on those pages, the appeal is the right vehicle.
A motion under CPL 440.10 does the opposite. It goes back to the court that entered the conviction and raises facts that are not in the record — evidence nobody knew about at trial, a conflict the defense never learned of, misconduct that happened out of the jury’s sight. Because those facts live outside the transcript, an appellate court generally can’t consider them, which is exactly why this separate procedure exists.
The two can also work together. It’s common for a CPL 440 motion and an appeal to proceed in parallel, each handling the part of the problem it’s built for.
The Grounds That Actually Qualify
Article 440 of the New York Criminal Procedure Law sets out specific grounds rather than a general invitation to re-argue the case. The ones that come up most often:
- A constitutional violation denying due process through the prosecutor’s failure to disclose favorable evidence — this is the broadest category and the one that carries most Brady claims.
- Newly discovered evidence, where the evidence could not have been produced at trial with due diligence and would probably have changed the result.
- Material evidence that was false, where the prosecution knew or should have known it was false.
- Fraud, misrepresentation, or duress on the part of the prosecutor or the court in procuring the judgment.
- The court lacked jurisdiction over the defendant or the case.
- DNA testing results that undermine the conviction.
What is not on that list matters just as much. A CPL 440 motion is not a second chance to argue the jury got it wrong, or that a witness was unconvincing. It needs a specific, identifiable defect.
Timing: The Good News and the Catch
Unlike most legal deadlines, there is generally no statute of limitations on the main CPL 440.10 grounds. A motion can be brought years or decades after sentencing. That’s genuinely unusual, and it’s why these cases sometimes surface long after everyone assumed the matter was closed.
The catch is procedural rather than chronological. The statute requires a court to deny a motion in certain situations — most commonly when the issue was already decided on direct appeal, or when the facts were on the record and could have been raised on appeal but weren’t. In other words, the thing that makes a CPL 440 motion powerful, that it reaches outside the record, is the same thing that limits it. Record-based claims belong on appeal, and raising them late in a CPL 440 motion usually fails.
What Happens After It's Filed
The court can decide the motion on the papers, or it can order a hearing where witnesses testify and evidence is presented. A hearing is often the practical goal, because most CPL 440 claims turn on facts that have never been examined in a courtroom.
If the motion succeeds, the conviction is vacated. That does not automatically mean the case is over — the prosecution may retry the case, or dismiss it, or the parties may resolve it another way. Vacatur reopens the matter rather than ending it.
Where a CPL 440 Motion Leads Afterward
For people who are ultimately cleared, a successful CPL 440 motion is often the first step in a longer sequence rather than the finish line. Having a conviction vacated is a precondition for other claims: New York’s compensation statute for the wrongfully convicted requires a qualifying vacatur or pardon before a claim can even be brought, which we cover on our wrongful conviction and actual innocence page. Separately, if the conviction resulted from misconduct rather than honest error, there may be civil claims against the agencies or individuals responsible — the subject of our articles on malicious prosecution and Brady violations.
Those are separate cases with separate standards. None of them follows automatically from a vacated conviction.
If You're Considering One
The practical starting point is identifying what specifically went wrong and whether it appears in the trial record. That single question usually determines whether the issue belongs in a CPL 440 motion, on appeal, or nowhere at all. Old case files, trial transcripts, and the names of prior counsel are the raw material, and tracking them down takes longer than most people expect.

Frequently Asked Questions
What is a CPL 440.10 motion in New York?
It’s a motion asking the court that entered a conviction to vacate it, based on facts outside the trial record — such as newly discovered evidence, a constitutional violation, or fraud in obtaining the judgment.
How is a CPL 440 motion different from an appeal?
An appeal reviews errors visible in the trial record. A CPL 440 motion raises facts that are not in the record and that an appellate court generally cannot consider.
Is there a deadline to file a CPL 440.10 motion?
There is generally no statute of limitations on the main grounds, so a motion can be filed years after sentencing. Procedural bars still apply, particularly where the issue was already decided on appeal or could have been raised there.
What happens if a CPL 440 motion is granted?
The conviction is vacated. The prosecution may then retry the case, dismiss it, or resolve it another way — vacatur reopens the case rather than automatically ending it.
Does a vacated conviction mean I can sue or receive compensation?
Not automatically. A qualifying vacatur or pardon is a precondition for New York’s wrongful conviction compensation claim, and any civil claim for misconduct has its own separate standards and deadlines.
