The first Wikimedia project to use an arbitration committee was the Swedish Wikipedia.
 The English Wikipedia ArbCom was created by Jimmy Wales as an extension of the decision-making power he formerly held as CEO of site-owner Bomis Inc., to take over his role in resolving complex disputes between users.
Arbitration Committees are now used on eleven Wikipedia versions and the English Wikinews.
Committees typically have five to fifteen members, who are known as Arbitrators. Terms vary in length, with some as long as three years.
On the English Wikipedia, Jimmy Wales has reserve authority to appoint and dismiss committee members, or to disband the committee and force new elections. Previously, non-binding community votes were used to present candidates for appointment. The community now runs standard elections to select committee members.
