Motion for New Trial in Texas Criminal Cases

What a Motion for New Trial Is

A motion for new trial is a written request asking the same trial court that convicted a defendant to set aside the verdict, judgment, or sentence and hold a new trial. In Texas criminal cases it is governed by Rule 21 of the Texas Rules of Appellate Procedure and is filed at the trial-court level after conviction but before appeal.

Despite its name, a motion for new trial is not an appeal. An appeal asks a higher court to review the trial record for legal error. A motion for new trial asks the trial judge who heard the case to correct a serious problem, sometimes based on facts that are not yet in the appellate record. That difference is what gives the motion its strategic value: it is the defendant's one clear opportunity to place new facts, such as affidavits, testimony, and exhibits, before the court while the case is still at the trial level.

Motion for new trial

A post-verdict request under Tex. R. App. P. 21 asking the trial court to vacate the conviction and grant a rehearing of the case on a recognized legal ground.

Motion for new trial on punishment

A narrower request seeking only a new punishment hearing rather than a complete retrial, available when the error affected sentencing alone.

Rule 21.1 defines both a new trial, meaning a rehearing of the case after the verdict is set aside, and a new trial on punishment, meaning a new hearing limited to assessing punishment. A defendant is never required to file a motion for new trial in order to appeal, but the motion is necessary whenever the defense must develop facts outside the existing record, such as evidence of jury misconduct or ineffective assistance that the trial record does not already show.

The Strict Deadlines Under Rule 21

The deadlines in Rule 21 are strict and largely jurisdictional, and missing them usually forfeits the motion entirely. Every clock starts when the trial court imposes or suspends the sentence in open court, not when the written judgment is later signed, so identifying the trigger date correctly is the first and most important step.

A motion for new trial must be filed within 30 days after sentencing (Rule 21.4(a)). The defendant may amend it within that same 30-day window, but only before the court rules on any earlier version (Rule 21.4(b)). Filing alone is not enough. The motion must also be presented to the court within 10 days of filing, meaning the defense must actively bring it to the judge's attention and request a ruling or hearing (Rule 21.6). The court may permit presentment up to 75 days after sentencing.

The 75-day rule is unforgiving. If the trial court does not sign a written order granting or denying the motion within 75 days of sentencing, the motion is overruled by operation of law, even if a hearing was scheduled but never held. A docket notation is not always sufficient, so the safest practice is a signed, written order. Because these dates cannot be extended by agreement, defense counsel typically calendars all of them the day sentence is pronounced.

The Recognized Grounds for a New Trial

Rule 21.3 lists eight circumstances in which a defendant must be granted a new trial. The Texas Court of Criminal Appeals has held that this list is illustrative rather than exclusive, so a trial court may also grant a new trial in the interest of justice on any other valid legal claim that shows a serious, rights-affecting flaw.

The enumerated grounds in Rule 21.3 are:

• (a) when the defendant has been unlawfully tried in absentia or denied counsel;
• (b) when the court has misdirected the jury about the law or committed a material error likely to injure the defendant's rights;
• (c) when the verdict was decided by lot or in a manner other than a fair expression of the jurors' opinion;
• (d) when a juror was bribed to convict or engaged in other corrupt conduct;
• (e) when a material defense witness was kept from court by force, threats, or fraud, or when exculpatory evidence was intentionally destroyed or withheld;
• (f) when, after retiring to deliberate, the jury received other evidence, a juror talked with someone about the case, or a juror became so intoxicated that the vote was probably influenced;
• (g) when the jury engaged in misconduct so serious that the defendant did not receive a fair and impartial trial; and
• (h) when the verdict is contrary to the law and the evidence.

In practice, four categories dominate motion practice. The interest-of-justice doctrine from State v. Herndon also limits a judge's discretion: the court cannot grant relief out of sympathy, on an inarticulate hunch, or because it believes the defendant simply received a raw deal, but only on a claim grounded in law.

The Hearing and the Affidavit Requirement

A hearing on a motion for new trial is not automatic. To earn one, the motion must raise a matter that cannot be determined from the existing record, and it must be supported by an affidavit, filed with the motion, showing reasonable grounds for the relief requested. Without that affidavit, the motion is treated as a bare pleading and may be denied without a hearing.

Rule 21.2 provides that a motion for new trial is a prerequisite to raising a point on appeal only when it is necessary to adduce facts not otherwise in the record. Rule 21.7 lets the court receive evidence at the hearing by affidavit or live testimony. The affidavit requirement works as a screening device: it forces the defense to show, up front, that the claim has factual substance before the court invests time in a hearing.

Limits on juror testimony

When the ground is jury misconduct, Texas Rule of Evidence 606(b) sharply limits what jurors may say. A juror generally may not testify about deliberations, statements made during them, or the mental processes behind a verdict. A juror may testify only about whether an outside influence was improperly brought to bear, or to rebut a claim that the juror was not qualified to serve.

In Colyer v. State, the Court of Criminal Appeals held that ordinary pressures, such as bad weather or a worried phone call from home, are not outside influences, because they are not brought to bear with intent to affect the verdict. Courts also apply an objective reasonable-person test and do not allow a juror to testify about how an influence actually affected that particular juror. These limits make the affidavit stage decisive, because the admissible evidence is narrow.

How the Motion Extends the Appellate Timetable

Even when a motion for new trial is unlikely to be granted, filing one has a concrete procedural benefit: it extends the deadline to file a notice of appeal. Under Rule 26.2(a), a defendant normally has 30 days after sentencing to file the notice of appeal, but a timely motion for new trial stretches that deadline to 90 days.

That additional time matters. It gives appellate counsel roughly two more months to obtain the reporter's record, evaluate the issues, and prepare the appeal. For this reason, defense lawyers frequently file a motion for new trial to preserve the longer timetable, even when the primary strategy is a direct appeal rather than trial-court relief.

Preserving issues that need a record

Some claims cannot be raised effectively on direct appeal because the trial record is silent about them. Ineffective assistance of counsel is the classic example, because the record rarely explains why counsel did or did not take a particular step. A motion for new trial is the vehicle that lets the defense build that record through affidavits and testimony, so that an appellate court has something concrete to review. Without it, the claim is usually pushed to post-conviction habeas corpus.

The timing interlocks with the deadlines in Rule 21. Because the motion must be filed within 30 days and the appellate clock is measured from the same sentencing date, counsel cannot treat the two deadlines as separate problems. Missing the 30-day filing window forfeits both the motion and the extended 90-day appellate timetable.

The Standard of Review: Abuse of Discretion

An appellate court reviews a trial court's ruling on a motion for new trial only for an abuse of discretion. That is a deferential standard: the reviewing court does not substitute its own judgment, and it reverses only when no reasonable view of the record could support the trial judge's decision.

In Colyer v. State, the Court of Criminal Appeals restated the framework. The reviewing court views the evidence in the light most favorable to the ruling and presumes that all reasonable factual findings were made in the ruling's favor. At the hearing, the trial judge alone determines witness credibility and may disbelieve even uncontroverted testimony. In Keeter v. State, the court applied that same deference to a recanting witness, holding that a judge may reject a recantation so long as the record gives some basis to doubt it.

A trial judge abuses his discretion in denying a motion for new trial when no reasonable view of the record could support his ruling. (Colyer v. State, 428 S.W.3d 117 (Tex. Crim. App. 2014))

The same deference cuts the other way when a judge grants a new trial. Under State v. Herndon, an order granting a new trial will be upheld if the defendant articulated a valid legal claim, pointed to evidence in the record that substantiated it, and showed prejudice to substantial rights. But the discretion is not unbounded, and a grant based on a legally invalid reason is itself an abuse of discretion. This is why the written grounds in the motion, and the evidence developed at the hearing, tend to decide the outcome.

Developing the Record for Ineffective Assistance

Ineffective assistance of counsel is one of the most common, and most record-dependent, grounds raised in a motion for new trial. Under Strickland v. Washington, a defendant must prove two things: that counsel's performance fell below an objective standard of reasonableness, and that the deficient performance prejudiced the defense.

Prejudice under Strickland means a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different, which the Court described as a probability sufficient to undermine confidence in the outcome. Courts apply a strong presumption that counsel's conduct fell within the wide range of reasonable professional assistance, and they judge the decisions from counsel's perspective at the time rather than with hindsight.

Why the motion matters for this claim

Because the two-prong test turns on why trial counsel acted as they did, the appellate record is usually silent on the decisive facts. A motion for new trial is the defense's first real chance to develop them, through affidavits from trial counsel, testimony at the hearing, and documentary evidence about what was and was not investigated. An appellate court can review only what the record actually contains.

When the record is not developed at this stage, an ineffective-assistance claim rarely succeeds on direct appeal. It is instead deferred to a post-conviction application for a writ of habeas corpus under Tex. Code Crim. Proc. art. 11.07, where an evidentiary record can be built later. Developing the facts early, while memories and files are fresh, is the practical reason the motion-for-new-trial stage is so important for these claims.

Where the Motion Fits in Texas Criminal Procedure

A motion for new trial is one of several post-verdict tools in Texas criminal procedure, and each has a distinct job. Seeing where the motion sits, alongside a motion in arrest of judgment, a direct appeal, and post-conviction habeas, helps explain when it is the right instrument and when another tool is better suited.

The motion for new trial and the motion in arrest of judgment often overlap. A motion in arrest of judgment attacks a defect that appears on the record itself, such as a charging instrument that fails to allege an offense, and it can be raised in the same 30-day window. A motion for new trial, by contrast, reaches beyond the record to new facts.

The motion also serves as a bridge to the appellate courts. By extending the appellate timetable and creating a factual record, it shapes which issues an appellate court can later consider. Claims that cannot be developed here typically move to habeas corpus, where a court can hold a separate evidentiary hearing. Choosing among these tools, and often using more than one, is a case-specific decision that depends on the error involved and the state of the record.

Common Situations & Variations

This motion comes up in several recurring situations. Each guide below walks through a specific fact pattern, the governing standard, and how Texas courts have handled it.

What the Case Law Says

These decisions—verified against primary sources—control how this motion is litigated. Every case still turns on its own facts.

• State v. Herndon, 215 S.W.3d 901 (Tex. Crim. App. 2007) — A trial court may grant a new trial only on a valid legal claim showing a serious flaw affecting the defendant's substantial rights, not sympathy.
• Colyer v. State, 428 S.W.3d 117 (Tex. Crim. App. 2014) — Denial of a new trial is reviewed for abuse of discretion; a claimed outside influence must be improperly brought to bear on a juror.
• Keeter v. State, 74 S.W.3d 31 (Tex. Crim. App. 2002) — Newly discovered evidence warrants a new trial only if unknown despite diligence, admissible, not merely cumulative, and probably true to change the result.
• Strickland v. Washington, 466 U.S. 668 (1984) — Ineffective-assistance relief requires deficient performance below professional norms plus prejudice: a reasonable probability the result would otherwise have differed.
