Some people are ineligible for jury service, principally those who are suffering from a mental disorder. Members of the clergy and those involved with the administration of justice (e.g. solicitors, barristers, judges, magistrates, police officers and probation officers) were previously also ineligible, but such ineligibility was removed following implementation of the relevant provisions of the Criminal Justice Act 2003.
Anyone who has served a term of imprisonment of five years or more, or who has been sentenced to imprisonment or a suspended sentence of imprisonment or a community order within the last ten years.
Certain people may be excused from jury service. Previously, those such as members of the medical and legal professions, MPs and members of the armed forces, as well as those over the age of 65, were excused as of right. However, the Criminal Justice Act 2003 altered the law such that excusal from (or deferral of) jury service is now only possible on the basis of good reason.
