In 1796 Washington appointed him as a commissioner representing the United States to handle maritime claims under the terms the Jay Treaty . As a result the Gores moved to England that year , establishing a residence in the fashionable Hyde Park area . The commission was established to arbitrate claims emanating from British seizures of American vessels and cargoes , and from British claims relating to violations of American neutrality in the ongoing French Revolutionary Wars . It consisted of three Americans ( Gore , William Pinkney , and John Trumbull ) and two British commissioners ( John Nicoll and Nicholas Astley ) ; Trumbull was chosen by the other four because he was deemed to sufficiently " fair @-@ minded " to cast deciding votes in the event of disagreements . That year he was also elected a Fellow of the American Academy of Arts and Sciences .
