[1] In 1302 he was itinerant justice for County Meath,[3] and received £20, in part payment of his salary of £40 per annum.
[1] In that capacity he went on assize to County Tipperary again (sitting in Cashel) with Walter de Thornbury, the Lord Chancellor of Ireland, in March.
[6] The two judges held a second session of the assize in Cork City in early August 1313.

[7] As was customary the younger William was given the power to appoint an attorney to manage his Irish affairs during his absence.
