What Happens When There Is a Mistrial

In Texas, a mistrial often creates confusion and stress for everyone involved, from the accused to their family members. What happens when there is a mistrial varies depending on the reason the trial ended, whether the prosecution chooses to pursue another trial, and how double jeopardy rules apply under state law. At the Law Office of David D. White, PLLC, we step in to safeguard our clients and build a strategy for the next phase once a trial has been cut short.

What Is a Mistrial?

A mistrial occurs when a criminal trial cannot continue or reach a valid verdict. Under Texas law, this result makes the entire trial void, as though the proceedings never happened. Article 45A.165 of the Texas Code of Criminal Procedure specifically requires a judge in a justice or municipal court to discharge the jury if it cannot agree on a verdict after deliberating for a reasonable time, and the justice or judge may then impanel a new jury to retry the case as soon as practicable.

When a mistrial occurs, prior testimony and arguments lose legal effect, and the case resets. The defendant receives neither a conviction nor an acquittal, leaving prosecutors free to proceed with charges. Defense counsel must be ready to respond promptly and strategically when a case returns to the docket after a mistrial.

When Can a Judge Declare a Mistrial?

A judge may declare a mistrial if the jury cannot agree or when an error undermines fairness. Texas law provides explicit guidance. Article 37.07, Section 2 of the Texas Code of Criminal Procedure directs judges to declare a mistrial and release the jury when jurors cannot reach a unanimous decision on guilt or innocence. In that situation, jeopardy does not attach, leaving the state free to bring the case again with a new jury.

Beyond jury deadlock, several other circumstances can justify a mistrial:

• Juror misconduct, like discussing the case outside of deliberations
• Procedural mistakes that harm one side’s ability to present evidence
• Introduction of inadmissible and highly prejudicial material
• Illness or unavailability of jurors, attorneys, or the judge

These situations highlight why judges sometimes have no choice but to end a trial prematurely.

What Are the Consequences of a Mistrial?

The immediate consequence is that the trial ends without a verdict. For the defendant, this outcome can bring mixed emotions. Relief may come from avoiding a conviction, yet uncertainty often follows because the case remains unresolved. What happens next depends largely on the prosecutor’s response, which can take several different paths, including:

1. Refile the case and start again with a new jury.
2. Negotiate a plea agreement.
3. Dismiss the charges altogether.

Prosecutors weigh the strength of their evidence, the cost of another trial, and the reason for the mistrial. For example, a hung jury split 11–1 for acquittal might discourage the state from retrying, while a split favoring conviction may prompt another trial.

Does a Mistrial Always Result in a Criminal Case’s Dismissal?

A mistrial does not automatically dismiss charges. Because a mistrial leaves the case undecided, prosecutors can often retry. Whether dismissal occurs depends on prosecutorial discretion, defense motions, and constitutional protections. Defense attorneys frequently challenge a retrial by arguing double jeopardy applies, or by filing motions to suppress evidence if errors influenced the original proceeding.

Understanding what happens when there is a mistrial in Texas helps defendants see that a case does not end simply because a trial collapsed. Instead, the outcome depends on prosecutorial choices and the legal strategies raised in response.

Mistrials vs Hung Juries: Is There a Difference?

Yes, a hung jury is one type of mistrial, but not the only cause. Many people use the two terms interchangeably, but they actually describe different stages of courtroom breakdowns. Understanding the difference matters because the path forward for the defendant often depends on why the mistrial occurred. If jurors cannot agree, the prosecution may still have a strong case for retrial, but if the mistrial results from procedural misconduct or judicial error, the defense may gain leverage in arguing against another trial.

Mistrial

A mistrial ends a criminal case before the jury can deliver a verdict. This outcome can result from a hung jury, serious procedural misconduct, or other extraordinary problems that undermine fairness. When a mistrial is declared, the proceedings are treated as void, meaning the testimony, evidence presentation, and arguments from the trial hold no legal weight moving forward. The defendant remains in a state of uncertainty, since no conviction or acquittal exists on record. Afterward, depending on the situation, prosecutors may decide whether to retry the case from the beginning, pursue a negotiated plea, or dismiss the charges altogether, often weighing the strength of the evidence and the reason the mistrial occurred.

Hung Jury

A hung jury occurs when jurors cannot agree on a unanimous decision. Because Texas requires full agreement in criminal cases, any deadlock obligates the judge to call a mistrial. Unlike mistrials caused by procedural errors or misconduct, a hung jury highlights disagreement among jurors about the strength or credibility of the evidence. When this happens, the case has not convinced all panel members beyond a reasonable doubt, leaving prosecutors to determine whether another trial is worth pursuing.

In short, every hung jury produces a mistrial, but not every mistrial stems from a hung jury.

Does Double Jeopardy Protect You if There’s a Mistrial?

Not always. Double jeopardy laws prevent someone from facing repeated prosecutions for the same offense, but those protections do not automatically apply after a mistrial.

Texas courts typically allow retrial when a mistrial occurs because of a hung jury or unforeseen procedural breakdown. The reasoning is that jeopardy does not “attach” when a jury fails to reach a lawful verdict. On the other hand, if prosecutorial misconduct intentionally provoked a mistrial, the defense may argue that double jeopardy bars another trial.

It’s important to understand how courts interpret these rules. An attorney can assess if your situation qualifies for double jeopardy protection and, if appropriate, file motions to prevent a retrial.
