In criminal courts the jury normally starts with 12 members and may, with the agreement of both sides continue with as few as 10, if some jurors are unable to attend. The Crown Court may now accept a majority verdict -- if only one or two jurors dissent -- in some cases.

Civil courts rarely use juries. The main exception to this is in defamation cases. Where they do, the High Court uses 12 and county courts 8.

Jurors are picked from the electoral role, but some professional groups are exempt.
