Do all jurors have to agree in order to find someone not guilty?

Answer 1

No. Indeed in Scottish law there is provision for a 3rd outcome: Not Proven. It was once the case that juries had to be unanimous, but now they have majority verdicts. Sometimes a majority decision cannot be reached.

Answer 2

A jury is usually sent to deliberate with an instruction from the judge to reach a verdict on which they are all agreed (a unanimous verdict). If, after a certain time, they return to say that they cannot all agree, the judge may (in certain types of cases) tell them that a majority verdict would be acceptable. The judge would usually indicate what majority would be acceptable.... usually no less than 10:2.

Different jurisdictions have different rules on this.

Answer 3

For criminal cases, most states require a unanimous decision on behalf of the jury, which usually is made up of 12 people. In 1972, the supreme court ruled that unanimous decisions were not required to deliver verdicts of either guilt or innocence, and most states use a majority vote system to determine verdicts in civil cases. Oregon and Louisiana currently are the only states that allow majority vote for determining criminal cases.

Answer 4

It depends on the country's legislative system, but as a rule, jury is ought to vote.

Another View: It can depend on the jurisdiction (as noted above). Certain mionor offenses (some misdemeanor and traffic offenses) can be tried with juries of less than 12 persons, and unanimous jury verdict ios not necessary to convict. For capital crimes however, a full jury of 12 is required and the verdict must be unanimous.
