Hung jury
{{short description|Legal term for a jury that cannot agree on a verdict}}
{{for|the album|Hung Jury (album){{!}}Hung Jury (album)}}
A hung jury, also called a deadlocked jury, is a judicial jury that cannot agree upon a verdict after extended deliberation and is unable to reach the required unanimity or supermajority. A hung jury may result in the case being tried again.
This situation can occur only in common law legal systems. Civil law systems either do not use juries at all or provide that the defendant is immediately acquitted if the majority or supermajority required for conviction is not reached during a singular, solemn vote.
Australia
Majority (or supermajority verdicts) are in force in South Australia, Tasmania, Western Australia, the Northern Territory, Victoria, New South Wales, and Queensland. Australian Capital Territory and Commonwealth courts require unanimous verdicts in criminal (but not civil) trials.{{Cite web|url=https://support.thomsonreuters.com.au/product/westlaw-au/updates-alerts/ten-or-eleven-out-twelve-aint-bad-not-crimes-against-commonwealth|title = Ten or Eleven Out of Twelve Ain't Bad|date = 25 November 2014}}
Canada
In Canada, the jury must reach a unanimous decision on criminal cases. If the jury cannot reach a unanimous decision, a hung jury is declared. A new panel of jurors will be selected for the retrial. Each jury in criminal courts contains 12 jurors. In civil cases, only six people are necessary for a jury, and if there is only one dissenter (i.e. a 5–1 vote), the dissenter can be ignored with the majority opinion becoming the final verdict.{{cite web |url = http://www.justice.gc.ca/eng/csj-sjc/just/12.html|title = Canada's System of Justice: The Role of the Public|publisher = Department of Justice|date = 2015-05-07}}
New Zealand
In New Zealand, the jury must try to reach a unanimous verdict. If the jury cannot reach a unanimous verdict after a reasonable time given the nature and complexity of the case (but not less than four hours), then the court may accept a majority verdict. In criminal cases, an all-but-one vote is needed (i.e. 11–1 with a full jury); in civil cases, a three-quarters (75%) vote is needed (i.e. 9–3 with a full jury).{{cite web |title=Juries Act 1981.

Majority verdicts have been allowed in England and Wales since the Criminal Justice Act 1967. Before this all criminal convictions required a unanimous verdict. At least 10 votes out of 12 is needed for a valid majority verdict. If fewer jurors remain, majorities allowed are 11–0, 10–1, 10–0, 9–1 and 9–0. Failure to reach this may lead to a retrial (R v. Bertrand, 1807).
Initially, the jury will be directed to try to reach a unanimous verdict. If they fail to reach a unanimous verdict, the judge may later give directions that a majority verdict will be acceptable, although the jury should continue to try to reach a unanimous verdict if possible. The judge may not give these directions before at least two hours{{cite web |title=Juries Act 1974 |url=http://www.legislation.gov.uk/ukpga/1974/23/data.htm |website=www.legislation.gov.uk}} of deliberation, however in practice it is often given after much longer than two hours.
When the jury is called to deliver a verdict after majority directions have been given, a careful protocol of questions is followed: only in the event of a guilty verdict is it asked whether all jurors were agreed on that verdict, to prevent any acquittal from being tainted by it being disclosed that any jurors dissented. The protocol is followed separately for each charge.{{cite web|url=http://www.justice.gov.uk/criminal/procrules_fin/contents/practice_direction/part4.htm|archive-url=https://web.archive.org/web/20100523054140/http://www.justice.gov.uk/criminal/procrules_fin/contents/practice_direction/part4.htm|url-status=dead|archive-date=23 May 2010|title=Part IV: Further Practice Directions Applying in The Crown Court|date=23 May 2010}} Majority verdicts are treated the same as unanimous ones, for example they are not taken as a mitigating factor during sentencing.{{cite journal |last1=Waller |first1=Nisha |last2=Sakande |first2=Naima |title=Majority jury verdicts in England and Wales: a vestige of white supremacy? |journal=Race & Class |date=1 April 2024 |volume=65 |issue=4 |pages=26–52 |doi=10.1177/03063968231212992 |url=https://doi.org/10.1177/03063968231212992 |language=en |issn=0306-3968|doi-access=free }}
= Scotland =
It is not possible to have a hung jury in Scotland in criminal cases. Juries consist of 15, and verdicts are decided by simple majority (eight) of the initial membership. If jurors drop out because of illness or another reason, the trial can continue with a minimum of 12 jurors, but the support of eight jurors is needed for a guilty verdict; anything less is treated as an acquittal.[http://www.oqps.gov.uk/legislation/uk/acts/acts1995/ukpga_19950046_en_9#pt7-pb8-l1g90 Criminal Procedure (Scotland) Act 1995] section 90
In civil cases there is a jury of 12, with a minimum of 10 needed to continue the trial. It is possible to have a hung jury if there is a tied vote after three hours' deliberation.http://www.legislation.gov.uk/ukpga/Geo5/23-24/41/section/11s
United States
Majority verdicts are not allowed in civilian criminal cases in the United States. A hung jury results in a mistrial. The case may be retried (United States v. Perez, 1824).
Louisiana, which was historically influenced by the French civil law system, and Oregon used to allow 10–2 majority verdicts. In the 2020 case Ramos v. Louisiana, the U.S. Supreme Court ruled that a jury must vote unanimously to convict in any criminal offense that requires a jury trial.
Some jurisdictions permit the court to give the jury a so-called Allen charge, inviting the dissenting jurors to re-examine their opinions, as a last-ditch effort to prevent the jury from hanging. The Federal Rules of Criminal Procedure state, "The verdict must be unanimous. ... If there are multiple defendants, the jury may return a verdict at any time during its deliberations as to any defendant about whom it has agreed. ... If the jury cannot agree on all counts as to any defendant, the jury may return a verdict on those counts on which it has agreed. ... If the jury cannot agree on a verdict on one or more counts, the court may declare a mistrial on those counts. A hung jury does not imply either the defendant's guilt or innocence. The government may retry any defendant on any count on which the jury could not agree."{{citation|url=https://www.law.cornell.edu/rules/frcrmp/rule_31|title=Rule 31|publisher=Federal Rules of Criminal Procedure}}
In jurisdictions giving those involved in the case a choice of jury size (such as between a six-person and twelve-person jury), defense counsel in both civil and criminal cases frequently opt for the larger number of jurors. A common axiom in criminal cases is that "it takes only one to hang," referring to the fact that in some cases, a single juror can defeat the required unanimity.{{cn|date=April 2025}}
One proposal for dealing with the difficulties associated with hung juries has been to introduce supermajority verdicts to allow juries to convict defendants without unanimous agreements amongst the jurors, but this would require amending the U.S. Constitution. For example, a 12-member jury that would otherwise be deadlocked at 11 for conviction and one against might be recorded as a guilty verdict. The rationale for majority verdicts usually includes arguments related to so-called 'rogue jurors', who unreasonably impede the course of justice. Opponents of majority verdicts argue that it undermines public confidence in criminal justice systems and results in a higher number of individuals to be convicted of crimes they did not commit.{{cn|date=April 2025}}
In United States military justice, there are no hung juries. If the threshold for a conviction is not met, the defendant is acquitted. Article 52 of the Uniform Code of Military Justice (10 U.S.C. Chapter 47) specifies the minimum number of court-martial panel members required to return a verdict of guilty. In a capital case, a unanimous vote of all panel members is required to convict on a capital charge.
In all other cases, only a three-fourths vote is required to convict. Additionally, the Manual for Courts-Martial requires only a judge and a specified number of panel members in all non-capital cases (eight for a general court-martial or three for a special court-martial; no panel is seated for a summary court-martial). In capital cases, a panel of 12 members is required.{{cn|date=April 2025}}
=Hung jury in capital sentencing=
Of the 27 U.S. states with the death penalty, 25 require the sentence to be decided by a jury.
Two states do not use juries in death penalty cases:
- In Nebraska the sentence is decided by a three-judge panel, which must unanimously agree on death, and the defendant is sentenced to life imprisonment if one of the judges is opposed.{{cite web|url=http://law.justia.com/codes/nebraska/2014/chapter-29/statute-29-2521/ |title=2014 Nebraska Revised Statutes – Chapter 29 – CRIMINAL PROCEDURE – 29-2521 – Sentencing determination proceeding. |publisher=law.justia.com |access-date=April 16, 2017}}
- Montana is the only state where the trial judge decides the sentence alone.{{cite web|url=http://leg.mt.gov/bills/mca/title_0460/chapter_0180/part_0030/section_0010/0460-0180-0030-0010.html |title= 46-18-301.

Two states do not require a unanimous jury decision:
- In Alabama, at least 10 jurors must concur, and a retrial happens if the jury deadlocks.{{Cite web |title=State of Alabama Criminal Code 2017 |url=https://inform.alabama.gov/_ALI/PDF/Book/complete_projects/Criminal%20Code%202017.pdf |access-date=27 March 2024 |website=inform.alabama.gov |page=76}}
- In Florida, at least 8 jurors (two-thirds) must concur, and the prosecution can pursue a retrial if the jury deadlocks.{{Cite web |title=Statute 921.141 - Sentence of death or life imprisonment for capital felonies; further proceedings to determine sentence |url=http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0900-0999/0921/Sections/0921.141.html |access-date=27 March 2024 |website=leg.state.fl.us}}
In all states in which the jury is involved, only death-qualified prospective jurors can be selected in such a jury, to exclude both people who will always vote for the death sentence and those who are categorically opposed to it. However, the states differ on what happens if the penalty phase results in a hung jury:{{cite web |title= Provisions of state and federal statutes concerning sentence if capital sentencing jury cannot agree |url=http://www.deathpenaltyinfo.org/documents/JuryDeadlockLaws.pdf |publisher= A.

- In five states (Alabama, Arizona, California, Kentucky and Nevada), a retrial of the penalty phase will be conducted before a different jury (the common-law rule for mistrial).See [https://supreme.justia.com/cases/federal/us/22/579/case.html United States v. Perez], 1824
- In two states (Indiana and Missouri), the judge will decide the sentence.
- In the remaining states, a hung jury results in a life sentence, even if only one juror opposed death. Federal law also provides that outcome.{{cite web |title=The Federal Death Penalty System: Supplementary Data, Analysis and Revised Protocols for Capital Case Review|publisher=U.S. Department of Justice|date=June 6, 2001|url=https://www.justice.gov/archive/dag/pubdoc/deathpenaltystudy.htm|quote=If the jury does recommend a capital sentence, the court is required to sentence the defendant accordingly.

The first outcome is referred as the "true unanimity" rule, while the third has been criticized as the "single-juror veto" rule.{{Cite web |last=Scheidegger |first=Kent S. |date=February 4, 2016 |title=Hurst v.
