A retrial is another trial of a case or issue that was previously tried. It may follow a mistrial, a successful motion for a new trial, or an appellate decision reversing the original result and returning the case to the trial court.

Key Takeaways
- A retrial repeats some or all of an earlier trial, usually because the first proceeding did not produce a valid final result or a court set its result aside.
- A mistrial ends a trial before a valid verdict, while a retrial is the later proceeding that may follow.
- A new trial is relief a court grants. Retrial describes the proceeding conducted after that relief.
- Double jeopardy generally bars a criminal retrial after an acquittal, but it does not prohibit every retrial after a mistrial or reversed conviction.
- Civil retrials may result from serious legal errors, misconduct, newly discovered evidence, unsupported verdicts, or improper damages, depending on applicable law.
- The court's order and applicable procedural and evidentiary rules determine the scope of the retrial, available evidence, judge assignment, and jury selection.
Retrial Meaning and Legal Definition
In law, the retrial meaning is straightforward: a court tries a previously tried case or issue again. The second proceeding may cover the entire case, only certain claims, or a limited question such as liability or damages. The controlling court order determines the scope.
The standard spelling is retrial, as one word. The term may also appear informally as re-trial. A search for "retrail" usually reflects a misspelling rather than a separate legal term. Someone who faces another trial is being retried, and the plural is retrials.
Although courts and lawyers sometimes use "retrial" and "new trial" interchangeably, the terms can describe different parts of the process. A new trial is a remedy granted by a trial or appellate court. A retrial is the proceeding held as a result. A mistrial, by contrast, ends the existing trial before it reaches a valid conclusion. An appeal asks a higher court to review claimed errors and does not itself retry witnesses or receive the case from the beginning.
Understanding the broader meaning of a trial in law can help clarify what must be repeated. A retrial generally returns the disputed issues to the trial level, where the parties present evidence and legal arguments under the court's directions.
| Procedure | When It Occurs | Who Initiates or Orders It | Was There a Verdict? |
|---|---|---|---|
| Retrial | After an earlier trial or terminated trial | Trial court, appellate court, or a party seeking relief | Possibly |
| New trial | After a verdict or judgment is challenged | A party moves, and a court grants relief | Usually |
| Mistrial | Before the current trial validly concludes | The judge, sometimes on a party's request | No valid final verdict |
| Appeal | After an appealable ruling or judgment | An eligible party files the appeal | Often |
How Does a Retrial Happen?
There are three common procedural paths to a retrial. First, a judge may declare a mistrial. A hung jury is a familiar example. If jurors cannot reach the verdict required by law, the judge may discharge them without resolving the case. Subject to constitutional and procedural limits, the parties may then prepare for another trial.
Second, the trial court may grant a motion for a new trial. A party usually files this motion after the verdict or judgment and identifies legally recognized grounds. Possible grounds include a significant legal or procedural error, juror or attorney misconduct, an irregular proceeding, newly discovered material evidence, a verdict against the weight of the evidence, or improper damages. The exact grounds, filing requirements, and deadlines depend on the jurisdiction and type of case.
Third, an appellate court may reverse a judgment and remand the case. A remand sends the matter back to the trial court for further proceedings. The appellate mandate may permit a complete retrial or restrict the new proceeding to particular claims, parties, defenses, or damages. Not every reversal produces a retrial. An appellate court may instead order another form of relief or direct entry of a particular judgment.
A retrial is therefore not automatic whenever a party identifies a mistake. Courts generally consider whether the asserted error was preserved, whether it was prejudicial, and whether applicable law authorizes a new trial. Parties should read the judgment, mistrial order, appellate opinion, and mandate together before assuming what happens next.
Criminal Retrials and Double Jeopardy
The Fifth Amendment protects a person from being placed twice in jeopardy for the same offense. This protection makes the result and circumstances of the first criminal proceeding critical. It does not mean that every second trial is unconstitutional.
An acquittal generally ends the prosecution for that offense, even if the government believes the acquittal resulted from legal or factual error. The government ordinarily cannot appeal an acquittal simply to seek another opportunity to convict. Double jeopardy also prevents the prosecution from repeatedly trying a person until it obtains the result it wants.
A hung-jury mistrial is different. When jurors cannot reach a verdict, the trial has not resolved guilt or innocence. A retrial ordinarily may follow that type of mistrial. Other mistrials require closer analysis. Relevant questions include who requested the mistrial, why it became necessary, and whether the judge considered reasonable alternatives. If prosecutorial conduct was intended to provoke the defendant into requesting a mistrial, double jeopardy may bar another prosecution.
The charges also matter. Courts analyze whether the later prosecution concerns the same offense for double jeopardy purposes, not merely whether it arises from related conduct. Separate sovereigns, multiple statutory offenses, and lesser-included offenses can raise additional questions beyond the basic rule.
A defendant can also choose to give up certain trial rights when the law permits. A jury trial waiver, for example, concerns who decides the facts. It does not by itself eliminate double jeopardy protection or authorize an otherwise prohibited retrial.
Retrial After Conviction
A retrial after conviction may occur when the trial court grants a new trial or an appellate court reverses the conviction. The reason for reversal determines whether prosecutors may try the defendant again.
If a conviction is reversed because of a legal error in the proceedings, a retrial is generally possible. Examples can include an incorrect jury instruction, an improper evidentiary ruling, or misconduct serious enough to undermine the trial's fairness. The reversal removes the defective conviction and allows the case to return to the trial court, subject to the appellate mandate.
The result differs when an appellate court finds the evidence legally insufficient to support the conviction. In that situation, double jeopardy generally prohibits a retrial. Insufficiency means the prosecution failed to present enough evidence to permit a conviction under the governing legal standard. It is distinct from a conclusion that a verdict was against the weight of the evidence, which can involve a trial judge independently evaluating credible evidence under applicable rules.
A defendant seeking another trial must identify an available procedural route. That may involve a timely new-trial motion, a direct appeal, or another form of post-conviction relief. Each route has separate standards and limits. A defendant cannot obtain a retrial merely by disagreeing with the jury's assessment. The request must rely on a recognized legal ground supported by the record, admissible new information, or both.
If a verdict, mistrial, or appellate ruling creates a possible retrial, an attorney can review the record and court orders, identify preserved errors and available grounds, and prepare the proper motion or retrial strategy.

New Trials and Retrials in Civil Cases
Civil cases do not involve the Fifth Amendment's criminal double jeopardy bar. A civil court may grant a new trial when applicable procedural law authorizes it and the moving party satisfies the required standard. The court may order a full retrial or limit it to a separable issue, such as damages.
Common grounds may include prejudicial legal error, improper admission or exclusion of evidence, juror misconduct, attorney misconduct, irregularities in the proceeding, newly discovered material evidence, a verdict unsupported by the evidence under the governing standard, or excessive or inadequate damages. A harmless mistake usually does not justify starting over. The moving party ordinarily must explain how the problem affected substantial rights or the outcome.
Contract and business disputes often reach this stage after a jury verdict. The underlying substantive issue remains relevant during the retrial. For example, a party disputing enforceability may also need to understand when it is possible to void a contract after signing. Allegations involving changed agreements may raise separate questions about altering a signed document.
New-trial law varies by jurisdiction. California Code of Civil Procedure section 657, for example, identifies California grounds and standards for granting a new trial. When excessive or inadequate damages are asserted, the statute addresses the court's review of the evidence and the verdict. California decisions, including Fortman v. Hemco Inc., discuss the trial court's role in independently weighing evidence and the deference given to that ruling on appeal. These are California-specific authorities, not universal rules for every state or federal court.
What Happens During a Retrial?
A retrial usually returns the case to a pretrial posture for the issues that remain open. The court may hold scheduling conferences, set deadlines, resolve motions, and determine which earlier rulings remain effective. The parties then prepare witnesses, exhibits, jury instructions, and legal arguments for the permitted scope of the new proceeding.
If the case will be tried to a jury, the court generally selects a new jury because the previous jury was discharged. Jury selection, opening statements, presentation of evidence, closing arguments, instructions, and deliberations may occur again. A bench retrial instead places fact-finding responsibility with the judge. The parties should not assume that the second proceeding will duplicate the first in every detail.
The appellate mandate or new-trial order may narrow the questions. For example, a civil liability finding might remain intact while damages are retried. In another case, an error affecting intertwined claims could require a broader proceeding. Parties may be unable to relitigate matters that the appellate court conclusively decided or that fall outside the remand.
Prior testimony and discovery do not automatically disappear. Lawyers often use transcripts to prepare witnesses, test credibility, or address inconsistent statements, subject to evidentiary rules. Existing pleadings, stipulations, and discovery may remain part of the case unless the court permits changes. The court may also reconsider earlier rulings when authorized, but a party should not assume every prior loss can be argued again.
The retrial produces its own verdict or decision. That result may lead to a new judgment and, where permitted, further post-trial motions or an appeal. The second result can match or differ from the first because the admissible evidence, rulings, jury, or scope may have changed.
Evidence, Judges, and the Scope of Retrials
New evidence may be introduced at a retrial, but there is no universal right to present anything discovered after the first proceeding. The evidence must satisfy the jurisdiction's evidentiary rules and any disclosure, discovery, or pretrial requirements. The new-trial order, appellate mandate, and scope of the remand may also restrict its use.
Newly discovered evidence can sometimes provide the reason for granting a new trial. Courts commonly examine when the evidence became known, whether reasonable diligence could have uncovered it earlier, whether it is material rather than merely cumulative, and whether it could affect the result. The precise test differs by court and type of case. Evidence that supports a motion does not avoid ordinary admissibility requirements at the retrial.
The same judge may handle the retrial, but reassignment is possible. Local assignment practices, recusal rules, appellate directions, scheduling, or a judge's unavailability can affect the decision. Dissatisfaction with prior rulings alone does not necessarily entitle a party to a different judge. Check the assigned court's orders and rules rather than assuming the judge will change.
A jury retrial ordinarily uses newly selected jurors. Former jurors have already heard the case and may have participated in deliberations, making them unsuitable for simply resuming the dispute. The new jury may hear a different presentation because the court corrected an error or limited the issues. If the parties validly waived a jury or the matter is not jury-triable, the judge may decide the retried issues.
Before preparing, identify exactly what the court authorized. The order may call for a full retrial, a damages-only trial, reconsideration of one claim, or another limited proceeding. That scope controls the evidence and strategy.
Frequently Asked Questions
What Is a Retrial in Court?
A retrial in court is a second judicial proceeding addressing a case or issue previously tried. It does not necessarily erase every earlier ruling. The court may preserve settled findings, restrict the issues, or require the parties to retry the entire case, depending on the mistrial order, new-trial ruling, or appellate mandate.
What Does "We're Having a Retrial" Mean?
"We're having a retrial" means the court will conduct another trial rather than leave the prior proceeding as the final resolution. The statement alone does not explain why. Court records should show whether a mistrial, post-trial motion, or appellate ruling caused the retrial and what issues remain open.
How Do You Get a Retrial?
You get a retrial by obtaining court-authorized relief through an available procedure, not simply by requesting another chance. Depending on the case, that may require a new-trial motion, a successful appeal, or a mistrial that legally permits another prosecution or civil trial. Applicable rules control the grounds, timing, supporting materials, and preservation requirements.
Can New Evidence Be Introduced in a Retrial?
Yes, new evidence can sometimes be introduced in a retrial if it is admissible and falls within the issues the court authorized for trial. Disclosure obligations and case-management deadlines still apply. Evidence offered after an appellate remand may also face restrictions based on matters the appellate court already resolved.
Is a Retrial Double Jeopardy?
No, a retrial is not automatically double jeopardy. The constitutional question depends on how the first criminal proceeding ended and why another trial is proposed. Because small factual distinctions can control the result, defendants should evaluate the exact charges, rulings, mistrial circumstances, and appellate disposition rather than relying only on the fact that this is a second proceeding.
Do You Get the Same Judge in a Retrial?
You may get the same judge in a retrial, but court assignment rules and case-specific orders control. A party seeking reassignment may need a legally recognized basis and must follow the court's procedure. Administrative reassignment can also occur without a party's request because of scheduling, retirement, recusal, or an appellate instruction.
