In the following years, Tresilian became increasingly involved in politics, as a loyal follower of the king. In
November 1386 Parliament appointed a commission to review and control royal finances. The king resented this infringement of his
royal prerogative and, in the so-called 'questions to the judges', he received legal backing for the position that the commission was unlawful. It is largely assumed that it was Tresilian who drafted the 'questions', and thereby turned a political controversy into a legal dispute. The king's opponents went on the counterattack. On 17 November 1387, Tresilian was among a number of royal loyalists who were charged with treason by the group of noblemen known as the
Lords Appellant. When Tresilian's case came up for trial, he had gone into hiding and was not to be found, and was sentenced
in absentia. On 19 February 1388, he was discovered hiding in
sanctuary in
Westminster. He was dragged into court with cries of 'We have him!' from the mob and, as he was already convicted, was summarily executed, being hanged naked before his throat was cut. == Reputation and family ==
