After a judge declares a mistrial, the charges against you remain active and your case essentially resets: the prosecution generally gets another chance to try you, and in federal court the clock to bring you back to trial is 70 days. A mistrial is not an acquittal and not a conviction. It is an unfinished proceeding, and what happens after a mistrial depends mostly on what the prosecutor decides to do next.
Where You Stand the Day the Mistrial Is Declared
You return to roughly the same position you were in before trial started. If you were out on bail, you stay out on bail. If you were in custody, you go back to jail. There is no automatic release because the trial fell apart. The court can revisit your bail conditions after a mistrial, but the baseline assumption is that whatever arrangement was in place before trial continues.
The charges themselves are unchanged. Nothing about the mistrial reduces them, dismisses them, or counts as a win on the merits. Your legal exposure is exactly what it was the morning jury selection began.
What the Prosecution Decides Next
The next move belongs to the prosecutor, who realistically picks from three paths.
Retrying the case is the most common choice. The process starts fresh with a new jury, and both sides get to adjust based on what they learned. A prosecutor who watched jurors struggle with a weak forensic argument might bring in a better expert. A defense attorney who saw which themes resonated can lean into them harder.
Offering a plea deal is the second option, and a mistrial often makes both sides more open to one. A hung jury tells the prosecutor that at least some jurors had doubts, so a conviction on retrial is far from guaranteed. At the same time, you know you could still be found guilty the second time around. That mutual uncertainty creates room for a negotiated resolution, often a plea to a lesser charge.
Dropping the charges is the third possibility, though it happens less often. A prosecutor might walk away if the mistrial exposed serious problems with the evidence, if a key witness is no longer available, or if a second trial is not worth the resources. The math matters here. A jury deadlocked 11-to-1 for conviction looks very different from one split down the middle. The first practically invites a retrial; the second suggests the case itself may be the problem.
How Long the Prosecution Has to Retry You
You do not have to wait indefinitely. In federal cases, the Speedy Trial Act requires the retrial to begin within 70 days of the mistrial declaration.1Office of the Law Revision Counsel. 18 USC 3161 – Time Limits and Exclusions If the government misses that window without a valid reason, you can move to have the charges dismissed.
The 70-day clock has exceptions. Certain delays do not count against the deadline, including time spent on pretrial motions, mental competency evaluations, and other proceedings the statute specifically excludes. Even so, the clock is a meaningful check against prosecutors dragging their feet while you sit in jail or live under pending charges. Most states have their own speedy trial rules with similar time limits, though the exact number of days varies.
Does Double Jeopardy Stop a Retrial
The first question most people ask after a mistrial is whether the government can really try them again for the same crime. The Fifth Amendment prohibits putting someone “twice in jeopardy” for the same offense, and at first glance a retrial seems to violate that rule.2Congress.gov. Constitution Annotated – Overview of Double Jeopardy Clause The protection is narrower than most people assume.
Jeopardy Has Attached, but It Was Not Resolved
Jeopardy does not attach when you are charged or arrested. In a jury trial, it attaches when the jury is sworn in. In a bench trial, it attaches when the first evidence is presented.3Congress.gov. Constitution Annotated – Amdt5.3.4 Re-Prosecution After Mistrial By the time a mistrial is declared, jeopardy has already attached. The question is whether it was properly resolved.
Double jeopardy protects you from being retried after a final verdict. An acquittal is final. A conviction is final. A mistrial is neither. The case was never decided, so the jeopardy you were placed in is treated as unresolved rather than concluded. That is why the government generally gets to try again.
Manifest Necessity
Courts allow retrials after mistrials under the doctrine of “manifest necessity.” When something makes a fair trial impossible, ending the trial and starting over is considered to serve everyone’s interests, including yours. A hung jury is the textbook example. So is a biased juror discovered mid-trial, or an emergency that forces the proceedings to stop.4Legal Information Institute. U.S. Constitution Annotated – Reprosecution After Mistrial
If you were the one who asked for the mistrial, double jeopardy almost never blocks a retrial. You cannot request a do-over and then argue the government should not get one too.
The Narrow Prosecutorial Misconduct Exception
There is one scenario where double jeopardy can bar a retrial. If the prosecutor deliberately provoked you into requesting a mistrial, the court can stop the government from trying again. The Supreme Court set this rule in Oregon v. Kennedy, holding that the Double Jeopardy Clause bars retrial only when the prosecutor’s misconduct was specifically intended to goad the defendant into moving for a mistrial.5Library of Congress. Oregon v. Kennedy, 456 U.S. 667 (1982)
The bar is intentionally high. General prosecutorial overreach, or even conduct bad enough to justify the mistrial itself, is not sufficient. You have to show the prosecutor acted with the specific goal of forcing the mistrial. Successful claims on this ground are rare.
How the Second Trial Differs from the First
A retrial is not a replay. Both sides have watched each other’s full case once, and they use that to adjust. Witnesses may be called in a different order. New expert testimony may be introduced. Arguments that fell flat can be reworked or abandoned. Your defense attorney gets the same advantage, having seen every card the prosecution played.
When a Witness From the First Trial Is Not Available
Months often pass between the mistrial and the new trial date. Witnesses sometimes move, become ill, or refuse to cooperate. Under Federal Rule of Evidence 804, if a witness who testified at the first trial is genuinely unavailable for the second, their earlier testimony can be read into the record, as long as the opposing side had a fair opportunity to cross-examine that witness the first time.6Legal Information Institute. Rule 804 – Hearsay Exceptions; Declarant Unavailable
“Unavailable” is broader than death or leaving the country. It also covers a witness who claims a privilege, refuses to testify despite a court order, or genuinely cannot remember the subject matter. The exception does not apply if the party trying to use the prior testimony is the one who caused the witness to become unavailable.6Legal Information Institute. Rule 804 – Hearsay Exceptions; Declarant Unavailable
The Cost of Going Again
Retrials are expensive for everyone. You face additional legal fees, more time away from work, and the strain of going through the process a second time. For defendants relying on court-appointed counsel, the burden shifts to a public defender system that may already be stretched thin. The prosecution also spends significant resources on a second trial. That shared reluctance is one reason plea negotiations become more attractive after a mistrial, and why many cases resolve before a second jury is ever sworn in.
