Before the council of Dublin, William de Vescy, inheritor of Co. Kildare and the appointed Lord Justice of Ireland, accused John FitzThomas, Baron of Offaly, of defamation before King Edward I and the council in England. FitzThomas had claimed that de Vescy described the king as the most perverse knight of the kingdom. He also claimed that de Vescy accused the King of cowardice during the siege of Kenilworth Castle and that he was organizing an uprising against Edward I. A battle followed and the two men were summoned before the king at Westminster. On this date, de Vescy appeared in Westminster but FitzThomas did not; de Vescy thus won his case by default.
