If a jury cannot agree on a verdict, it is known as a "hung jury" or "deadlocked jury". The judge will determine whether the jury is hung or deadlocked, and if further deliberations are unlikely to produce a verdict, the judge will declare a mistrial. In most jurisdictions in the United States, juries must be unanimous to reach a verdict, and if they cannot reach a unanimous verdict, the trial may result in a hung jury. However, in Oregon, non-unanimous jury verdicts are allowed, requiring only 10 of 12 jurors to reach a verdict. Non-unanimous jury verdicts are more common in civil cases, with perhaps as many as one-third of the states allowing for non-unanimous decisions of some kind. In New Zealand, the jury must initially try to reach a unanimous verdict, but if they cannot reach a unanimous verdict after a reasonable time given the nature and complexity of the case, then the court may accept a majority verdict. If the jury fails to reach either a unanimous or majority verdict after a reasonable time, the presiding judge may declare a hung jury, and a new panel of jurors will be selected for a retrial. If the retrial also results in a hung jury, the case must be referred to the Solicitor-General, who will generally issue a stay of proceedings unless there are compelling reasons to proceed with a third trial. If a mistrial occurs due to a hung jury, the prosecutor may decide to retry the case.
