Jury vetting is a term used in the United Kingdom to refer to the way in which members of a jury are checked for eligibility. There are two kinds of jury vetting: a criminal records bureau (CRB) check and an authorized jury check.
The first of these, the CRB check, is the most common. Everybody summoned for jury service will have been automatically subject to a CRB check.
An authorized jury check is more detailed and tends to be reserved for more politically sensitive cases, such as those involving national security or terrorism. They are intended to eliminate, as far as is possible, the likelihood of jury bias.
