A writ issued by Edward I commanding the Sheriff of Northumberland to summon Anthony de Bec, Bishop of Durham, to appear before the King to show cause why the Isle of Man should not be resumed into royal hands. The King asserts that his ancestors and he himself held Man as of right, and had granted it to John Balliol of Scotland while reserving royal rights. This document demonstrates early English Crown claims to sovereignty over Man and the legal mechanism of resumption.
