There were really constant disagreements, and sometimes the king degraded the mayor and appointed a custos or warden in his place.
Thus we hear of a custos palatinae capellae who was in charge of the palace chapel relics, and guarded them in the field; the chief of these custodes was sometimes called the archicapellanus.
To remedy this defect, a statute (called the Statute of Enrolments) was passed in the same year, which provided that every conveyance by bargain and sale of freehold lands should be enrolled in a court of record or with the custos rotulorum of the county within six months of its date.
Cecil, meanwhile, had obtained the reversion to the office of custos rotulorum brevium, and, according to his autobiographical notes, sat in.
About 1285 he was placed in charge of the abbey library as custos cartarum, and he died in June or July 1300.
