A unanimous verdict
The Judge will always seek a unanimous verdict first. That is a verdict upon which all the jurors are agreed, so either guilty or not guilty. In the early stages of a jury considering its verdict, a Judge cannot accept a majority verdict. If the jury are completely stuck the judge can accept a majority decision. When that happens varies from case to case. Generally, judges wait longer in the more serious cases such as murder, armed robbery or firearms offences.
If a judge decides to allow a majority verdict he will tell the jury that they should try hard to reach a verdict that they all agree with. If they cannot do that he will tell them that a majority verdict will be accepted. In a jury of 12 no more than two jurors can disagree. Where the jury has 10 or 11 members only one person may disagree. On the otherhand if there are 9 jurors the verdict must be unanimous. If the verdict is not guilty, the defendant is free to leave court (if there are no other matters remaining).
