A legal report to King James I from senior judges and nobles (Dorset, Shrewsbury, Worcester, Northampton) examining the Crown's title to the Isle of Man in relation to the Earls of Derby. The report identifies an imperfection in Henry IV's 1405 grant to Sir John Stanley and confirms the Derby family's continuous possession for approximately 200 years, ultimately deferring to the King's decision on how to proceed either by law or equity.
