A hung jury (or deadlocked jury) occurs when a jury cannot reach a unanimous or supermajority verdict after deliberation, typically resulting in a mistrial and the possibility of a retrial. This situation is most common in common law countries like the United States, the United Kingdom, Australia, Canada, and New Zealand, each of which has established specific procedures to manage it. In England and Wales, majority verdicts have been permitted since the Criminal Justice Act 1967, allowing for a 10-2 split or similar, though juries are first directed to try for unanimity. In Australia, most states allow majority verdicts, but the Australian Capital Territory and Commonwealth courts require unanimity for criminal trials. Canada mandates unanimous verdicts in criminal cases, leading to a mistrial if not reached, while civil cases allow a 5-1 vote to prevail. New Zealand initially requires unanimity, then accepts an 11-1 vote in criminal cases or a 9-3 vote in civil cases; if a retrial also hangs, the Solicitor-General typically issues a stay of proceedings.
