Morton was included in the Acts of Attainder passed by Richard III's first (and only) parliament which met at Westminster in January 1484 and he once again lost all his temporal possessions.Davies, C.

He was granted an unsolicited pardon on 11 December 1484 but he nevertheless refused to return to England. He is known to have been in Rome by 31 January 1485, when he signed the register of the Santo Spirito fraternity, and he was still there in April, when he secured a papal brief for the reform of Peterhouse, and probably on 7 May, when a papal indulgence was secured, the proceeds of which were to go to the repair of the dykes of the Isle of Ely and Ely Cathedral, damaged in recent floods. His real mission, however, may have been to secure papal dispensation for Richmond's intended marriage to Edward IV's eldest daughter, Elizabeth of York, which was necessary because both were descended from John of Gaunt.Davies, C.
