クラレンドン法
During the controversy between King Henry II of England and Archbishop Thomas Becket, Ridel supported the king. Ridel was one of the persons whom the Constitutions of Clarendon were addressed to, along with Richard de Luci and Richard of Ilchester. Ridel went to Rome in 1164 to represent the king before the papal curia, and in 1166 opposed Becket once more. By 1169 he was urging King Louis VII of France to no longer give refuge to Becket. Becket's supporters called Ridel the "archidiabolus", or "our archdevil", a play on the office of archdeacon which Ridel held. Ridel also urged King Henry's son, Henry the Young King, to refuse to see the archbishop in 1170, telling the prince that Becket wished to disinherit the prince.
