This case constitutes an appeal to the House of Lords and Court of Session regarding an infamous earlier case, dubbed "The Douglas Cause." That case, which was settled by the House of Lords in 1769, revolved around the contested inheritance of the vast wealth of the Duke of Douglas, who died in 1761. The heir-male to the Duke of Douglas, the Duke of Hamilton, contested the property claims of Archibald Douglas, the son of the Duke of Douglas' sister, from many angles. In this last-ditch appeal, brought before the Court of Session and House of Lords, the Duke of Hamilton asserted that a 1744 deed of revocation put forth by the late Duke of Douglas was in fact a settlement of succession that disinherited his sister, Lady Jane Douglas, from all properties that had been passed to the family through investiture. On December 19, 1778 the Court of Session found that the Duke of Hamilton had no claim under the deed of October 16th, 1744, declaring it a deed of revocation and not of settlement. On March 27, 1779 the House of Lords dismissed an appeal of the Duke of Hamilton. The memorials submitted to the Court of Session in October of 1778 contain a history of the Angus and Douglas families and their investitures, and an overview of similar cases to "The Douglas Cause."
