You were convicted in New York State. Your conviction was affirmed on appeal. Now what?

We do a heavy post-conviction practice and get numerous calls from inmates or their families telling us they - or their loved one-- blew trial and their conviction was affirmed. What are their options?

I explain that post-conviction lawyers are the oncologists of the legal profession. Our "patients" have contracted cancer and the cancer has metastasized.

But I explain all is not lost. The patient might still be saved.

First, we need to confirm that direct state review really is complete. If the Appellate Division has affirmed but no application for leave to appeal has yet been made to the New York Court of Appeals, that application generally must be filed within 30 days after service of the Appellate Division’s order. A petition for a writ of certiorari to the United States Supreme Court may also be available when the case presents a properly preserved federal question, but certiorari is discretionary and is not another routine appeal. Under the Supreme Court’s rules, the usual filing period is 90 days after entry of the relevant state-court judgment or the denial of discretionary review.

Apart from further direct review, two principal New York post-conviction routes may remain. A motion under Criminal Procedure Law Article 440 generally attacks the judgment entered in the trial court. A common-law writ of error coram nobis generally attacks the quality—or wrongful absence—of representation in the appellate court. They are not interchangeable. The first question is not simply “What went wrong?” but “Where did it go wrong, who was responsible, and what facts are needed to prove it?”

Relief from a trial conviction under Article 440

CPL 440.10 permits the court that entered the judgment to vacate it under certain limited circumstances. Although the statute says a motion may be made “at any time,” that does not mean delay is harmless. Some grounds have their own diligence requirements, evidence disappears, witnesses become harder to locate, and New York courts may reject claims that could have been raised in an earlier Article 440 motion.

Article 440 reaches several categories of error. CPL 440.10 covers lack of jurisdiction; a judgment procured through duress, misrepresentation, or fraud by the court or prosecution; material trial evidence known by the court or prosecutor to be false; prosecution evidence obtained in violation of constitutional rights; a defendant’s inability, because of mental disease or defect, to understand or participate in the proceedings; improper and prejudicial off-the-record trial conduct; newly discovered evidence; qualifying post-judgment DNA evidence; and judgments obtained in violation of the New York or United States Constitutions. It also contains specialized vacatur provisions, including provisions addressing trafficking victims and certain older convictions. If the problem is an unauthorized, illegally imposed, or otherwise invalid sentence rather than the conviction itself, CPL 440.20 is ordinarily the relevant provision.

A 440 motion is not a second direct appeal. A court generally must deny a claim already decided on the merits on direct appeal, absent a retroactively effective change in the law. Subject to statutory exceptions for ineffective-assistance claims, other claims may be barred when sufficient facts appeared in the record to permit adequate review on appeal, when the defendant unjustifiably failed to raise the issue earlier, or when the claim could have been raised in a prior 440 motion. Those procedural rules make claim selection and sequencing important: filing a thin motion now can make a stronger motion later much harder.

The motion must be written and supported by evidence. If the claim depends on facts, the papers should include sworn allegations from people with personal knowledge or identify the sources and basis of information and belief. Supporting records, correspondence, expert material, photographs, discovery, and other documentary proof should be attached when available.

A hearing is not automatic. A court may deny the motion without one when the papers do not state a legal ground, lack sworn support for essential facts, are conclusively refuted by unquestionable documentary proof, or rest on allegations that have no reasonable possibility of being true. If material factual disputes cannot otherwise be resolved, the court must conduct a hearing, where the defendant bears the burden of proving essential facts by a preponderance of the evidence.

The most common Article 440 claim: ineffective assistance of trial counsel

Ineffective assistance of trial counsel is one of the most frequently litigated Article 440 claims because the explanation for a lawyer’s conduct often is not in the trial record. Why was a witness not called? Was the witness interviewed? Did counsel review surveillance footage, retain an expert, investigate an alibi, convey a plea offer, advise the client about testifying, or recognize a conflict? Or fail to advise the client of a plea offer? A transcript may show what counsel did, but not why.

New York and federal law use related but distinct standards. Under the New York Constitution, the central question is whether counsel provided “meaningful representation,” considering the evidence, law, and circumstances in totality and as they appeared at the time. Courts avoid hindsight and generally require the defendant to rule out a strategic or otherwise legitimate explanation for the challenged conduct.

Under the federal Sixth Amendment standard established in Strickland v. Washington, the defendant must establish objectively deficient performance and a reasonable probability that, absent counsel’s errors, the result would have been different.

A serious motion should ordinarily address both standards. That is especially important if federal habeas review may follow. Labeling a claim only as a violation of New York’s meaningful-representation standard may fail to fairly present—or “federalize”—the federal Strickland claim.

The familiar statement that Article 440 is only for “off-record” ineffective-assistance claims is now incomplete. Current CPL 440.10 expressly exempts ineffective-assistance claims from two mandatory record-based denial provisions, and recent decisions recognize that a 440 court may consider an ineffective-assistance claim as a whole, including its record and nonrecord components. But two limitations remain critical. First, an ineffective-assistance issue already decided on the merits on direct appeal is ordinarily barred. Second, the court may reject a later motion when the defendant was positioned to raise the claim in an earlier 440 motion but failed to do so.

Proof matters more than accusations. A useful submission may include affidavits from uncalled witnesses, investigators, experts, family members, or the defendant; records showing what counsel possessed or failed to obtain; and evidence showing how the omitted investigation would have changed the defense. When an allegation concerns something peculiarly within former counsel’s knowledge, the motion should, where practicable, include counsel’s affirmation or explain documented efforts to obtain one. Courts routinely reject conclusory claims such as “my lawyer did not investigate” when the papers do not identify what an adequate investigation would have found and why it mattered.

Nor is every mistake constitutional ineffectiveness. Appellate courts distinguish deficient lawyering from reasonable but unsuccessful tactics. The strongest claims usually connect a concrete failure—such as overlooking a dispositive suppression issue, failing to investigate a readily available defense, giving materially incorrect plea advice, or laboring under an actual conflict—to a demonstrable effect on the fairness or reliability of the proceeding.

Another common claim: newly discovered evidence

CPL 440.10(1)(g) permits vacatur after a guilty verdict when evidence discovered after judgment could not, even with due diligence, have been produced at trial and creates a probability that the verdict would have been more favorable had the jury heard it. The motion also must be made with due diligence after discovery of the evidence.

New York decisions commonly ask whether the evidence:

was discovered after trial;
could not have been discovered earlier through due diligence;
is material to an issue in the case;
is not merely cumulative;
is not merely impeaching or contradictory; and
would probably produce a more favorable result.

The court evaluates the likely cumulative effect of the new proof together with the trial evidence; it does not consider the new item in a vacuum.

That makes credibility and corroboration essential. A witness recantation, for example, does not automatically entitle the defendant to a new trial. The motion should explain why the new account is reliable, why the witness testified differently before, what independent evidence supports the new account, and how the prosecution’s trial proof changes when the new evidence is added. An affidavit containing only a bare conclusion is rarely enough.

It is also important to plead the correct legal theory. Evidence discovered after trial is not always merely a “newly discovered evidence” claim. If the prosecution suppressed favorable, material evidence, the claim may arise under Brady v. Maryland and CPL 440.10(1)(h). If the prosecutor or court knowingly used materially false evidence, CPL 440.10(1)(c) may apply. In an appropriate case following a trial, counsel may also evaluate a freestanding actual-innocence theory under CPL 440.10(1)(h). The same facts can support more than one ground, and each ground may have different elements.

Ineffective assistance of appellate counsel: coram nobis

What if the principal failure occurred on appeal? A trial-court 440 motion is generally not the vehicle for claiming that appellate counsel mishandled the direct appeal. Under People v. Bachert, that claim is brought through a petition for a writ of error coram nobis filed in the Appellate Division that decided the appeal.

The governing New York standard is again meaningful representation. Appellate counsel is expected to demonstrate a competent grasp of the record, law, and appellate procedure, supported by appropriate authority and argument. But counsel is not required to raise every nonfrivolous issue. Effective appellate advocacy usually involves selecting the strongest points and omitting weaker ones. A coram nobis application therefore must do more than identify an issue that was not briefed.

A persuasive application generally identifies the omitted issue with precision; shows that it was preserved or otherwise reviewable; explains why it was clearly stronger than the issues counsel chose; demonstrates the governing law at the time of the appeal; and establishes a realistic possibility that competent presentation would have changed the appellate result.

Typical claims include failure to raise a preserved and outcome-determinative error, failure to present an obvious record-based ineffective-assistance claim, filing an inadequate brief, or, in narrow circumstances, wrongfully depriving the defendant of an appeal or an opportunity to seek further review.

Coram nobis is not a backdoor second appeal and does not directly relitigate every trial error. The omitted trial issue matters because it helps prove appellate counsel’s ineffectiveness. If relief is granted, the Appellate Division may vacate its prior order and reinstate the appeal, sometimes limited to the issue counsel should have raised.

There is no general statutory filing period for a traditional coram nobis application of this kind, and the Court of Appeals has said that passage of time alone does not automatically bar review. Delay is still dangerous. Records become incomplete, former counsel may be unavailable, and repetitive applications can be rejected. The application should be brought promptly once the claim and supporting record are assembled.

Appealing the denial of Article 440 or coram nobis relief

A trial court’s denial of a CPL 440.10 or 440.20 motion is not appealable as of right. The defendant must apply for a certificate granting leave to appeal from a single justice of the appropriate Appellate Division. The application must be made within 30 days after service of a copy of the order. Only one such application may be made. If leave is granted, the certificate and notice of appeal generally must be filed in the trial court within 15 days after issuance.

The leave application is not a formality. It should identify the legal or factual questions that warrant appellate review, address the motion court’s reasons, and include the papers required by the relevant Appellate Division department’s rules.

A single justice’s denial of leave from the 440 order is itself not appealable to the Court of Appeals. If leave is granted and the Appellate Division later decides the 440 appeal adversely, the defendant may seek leave to appeal that Appellate Division order to the Court of Appeals, subject to that court’s jurisdictional limits. Some discretionary determinations—particularly certain newly discovered evidence rulings—may effectively end at the Appellate Division.

A denial of coram nobis by the Appellate Division follows a different route. CPL 450.90 permits an appeal, by permission, to the Court of Appeals from an Appellate Division order granting or denying relief based on ineffective assistance or wrongful deprivation of appellate counsel. The criminal leave application generally must be filed within 30 days after service of the Appellate Division order. A motion for reargument does not stop that 30-day clock.

What comes next? Federal habeas corpus

After state remedies are complete, a person in custody under a New York judgment may consider a federal habeas petition under 28 U.S.C. § 2254. Federal habeas is not a general review of state-law error. The claim must allege custody in violation of the United States Constitution, federal laws, or treaties, and the petitioner generally must first exhaust available state-court remedies.

Exhaustion requires more than presenting similar facts. The state courts must be fairly alerted to the federal nature of the claim. That is why counsel should federalize issues from the beginning: identify the federal constitutional provision, cite the governing federal standard, and present the operative facts supporting that federal claim.

On direct review, exhaustion ordinarily includes seeking leave to appeal to the New York Court of Appeals. As noted earlier, after denial of a 440 motion, it includes seeking permission to appeal to the Appellate Division. If the Appellate Division grants leave but ultimately rejects the 440 claim, the defendant ordinarily should also seek Court of Appeals leave where that review is available. After denial of coram nobis, exhaustion ordinarily includes seeking leave to appeal to the Court of Appeals.

Timing is equally important. Federal law generally imposes a one-year limitation period running from finality of the conviction, subject to alternative starting dates and other rules in limited circumstances. A properly filed state post-conviction proceeding can toll the federal clock while it is pending, but it does not ordinarily restart time that already expired. The federal deadline should therefore be calculated before—not after—undertaking state collateral litigation.

Federal habeas also presents issues far beyond exhaustion and timing, including procedural default, the standard of review applicable to state-court decisions, the contents of the federal record, and the remedies a federal court can grant. Those subjects deserve their own article and are largely governed by the AEDPA - the Antiterrorism and Effective Death Penalty Act of 1996 -- so-called because its purpose was to reduce the prospects of habeas corpus relief-- particularly for death penalty defendants.

The bottom line

An affirmed conviction is a major setback, but it is not necessarily the end of the road. The next step depends on the source of the error and the proof available. Trial-level constitutional error, ineffective assistance of trial counsel, newly discovered evidence, prosecutorial misconduct, and illegal sentences generally point toward Article 440. Ineffective assistance or wrongful deprivation of appellate counsel generally points toward coram nobis in the Appellate Division.

The best post-conviction work begins with the complete file: the indictment, pretrial motions, hearing and trial transcripts, exhibits, discovery, trial counsel’s file, appellate briefs, appellate decisions, and leave applications. Build a chronology, separate record facts from nonrecord facts, identify every potentially available claim before filing, obtain sworn proof, and calendar every state and federal deadline.

In post-conviction litigation, the merits matter—but procedure often decides whether a court will ever reach them. You were convicted in New York State. Your conviction was affirmed on appeal. Now what?
