A nested charter document in which John de Stanley (Lord of Mann and the Isles, 1423) confirms a charter granted by Thomas Randulph (Earl of Moravia, Lord of Mann), who in turn had confirmed an earlier charter of King Magnus of Mann and the Isles to the Bishop of Mann and Sodor. The charter grants ecclesiastical liberties, lands (including the Island of St. Patrick), fisheries, customs rights, mining rights, and exemptions from secular service and exaction. This document provides evidence of medieval constitutional arrangements on the Isle of Man and the powers and property of the Church prior to the Revestment period.
