Trail's election was petitioned and overturned, with his election being declared void. Thomas Wallace, John Broadhurst and Trail was declared void after being found to have violated the Exemptions of Apothecaries Act 1694, and a by-election was held; Trail being the only one of the three never to return to Parliament.[1][2]
Due to this, Trail made no speeches in the House of Commons during his time as an MP.[3]
General Sir John Murray's election was not disturbed despite being of the same election.[1]
