クラレンドン法
In 1162, or 1163, Richard was appointed archdeacon of Poitiers, but he passed most of his time in England, although in the next two or three years he visited Pope Alexander III and the Emperor Frederick I in the interests of the English king. He was one of the persons whom the Constitutions of Clarendon were addressed, along with Geoffrey Ridel and Richard de Luci. For promising to support Frederick against Alexander he was excommunicated by Becket in 1166. Before this event, however, Richard had been appointed a baron of the exchequer. One of Richard's duties was to oversee the making of the Pipe rolls, as well as keeping the treasurer from falling asleep. He also was responsible for an innovation in record keeping by the Exchequer, ordering a record kept of every summons made by the Exchequer. This system, however, was discontinued later.
