In December 1295 he took office as justiciar, and organised a two-year truce between the feuding Burkes and Geraldines. In 1296 he organised a force with Richard Óg de Burgh, 2nd Earl of Ulster, Theobald Butler, and John FitzGerald, 1st Earl of Kildare, to assist Edward I in his war against the Scots; the king entertained them at Roxburgh Castle in May. After his return to Ireland, Wogan "kept everything so quiet that we hear of no trouble in a great while". The Parliament of Ireland he summoned in 1297 was for long compared to the English "Model Parliament" of 1295, though historical opinion now places less importance on it.
