A formal legal opinion by Attorney General Charles Searle and Deemster Peter John Heywood on John Quayle's memorial claiming ancient privileges belonging to the Barony of St. Trinions. The opinion addresses feudal tenure, fealty obligations, and the distinction between services owed to the chief lord versus the crown following the 1765 Revestment. It establishes that fealty arising from the barony can only be owed to the Duke of Athol, not the King.
