クラレンドン法
During early days of Becket's dispute with the king, Foliot helped mediate between Becket and Gilbert Foliot, who was supporting the king. Robert Foliot was one of the first of Becket's clerks to leave the archbishop's service, asking permission to leave Becket's household shortly after the council at Clarendon in January 1164, which ratified the Constitutions of Clarendon.
