Stannary, a general term used to cover the tin mines of a specified district, the miners themselves, and such customs and privileges as appertain to the workers and the mines. In England the term is specially associated with the stannaries of Devon and Cornwall, which by an Act of Edward III. were conferred in perpetuity upon the Prince of Wales as Duke of Cornwall, who holds the title of Lord Warden of the Stannaries. Special Stannary Courts for the administration of justice amongst those connected with the mines are held in the two counties, and are each presided over by a warden and a vice-warden. Up to 1752 representative assemblies of the miners, called Stannary Parliaments, were held. Appeals from the Stannary Courts may be made now to the higher courts of England.
