Westminster legislation authorising the Treasury to purchase the remaining Atholl rights in the Isle of Man after Revestment.

The 1765 settlement had transferred sovereign and customs rights to the Crown but had left the Atholl family with substantial proprietary interests. These included landed property and associated manorial rights, rents, services and ecclesiastical patronage which had not been absorbed into the original purchase.

The fourth Duke of Atholl continued to press claims arising from both the 1765 settlement and the rights which his family had retained. By the early nineteenth century further agreements had already produced additional compensation, including the annuity settled in 1805.

The Act of 1825, 6 Geo. IV c.34, authorised the Treasury to purchase the remaining rights from John, fourth Duke of Atholl. A later constitutional study cited in the evidence pack identifies him as Charlotte’s successor and the last Lord of Man.

The statutory authority did not itself mark the final physical completion of the transfer. The same account states that the final surrender to the Crown was made on 2 June 1828.

The 1825 measure therefore belonged to a sequence rather than a single transaction: the sovereign transfer of 1765, later compensation, the statutory authority of 1825 and the final surrender of the remaining rights in 1828.
