This rule explains when a judge can send a jury home before the trial fully wraps up with a verdict. There are three main situations where this happens. First, the judge lets the jury go once they've reached a verdict and the court has officially received it. Second, if the jury has been trying to reach a decision for a while but the judge believes they're truly stuck and won't ever agree, the judge can dismiss them. Third, if something serious happens during the trial that makes it impossible to continue fairly, like a major legal problem or an emergency, the judge can also let the jury go.
When any of these last two situations happen, meaning the jury didn't actually reach a verdict, the judge has to officially declare a mistrial. This means the trial doesn't count and legal proceedings will need to start over, often with a new jury. The court also has to write down the specific reason why the mistrial happened, so there's a clear record of what went wrong or why the trial couldn't finish.
For someone involved in a case, this rule matters because it means a trial isn't always guaranteed to end with a clear win or loss. If the jury can't agree or something forces the trial to stop early, the case isn't necessarily over. It just means the process may need to begin again.
