The Court of Exchequer, instituted by William the Conqueror, was, at first, only a simple court for receiving the accounts of the administration of the king's revenues, and those of the sheriffs, bailiffs, &c., and for judging the suits that arose on this subject. It was composed of barons, chosen by the king to form his council, and to aid him in his government. In proportion as the larger assembly, the _Curia regis_, came to be held less frequently, so did the Court of Exchequer gain in importance. The barons who composed it began to judge on their own responsibility, and alone, in the absence and before the convocation of the assembly; this change was introduced by necessity, confirmed by custom, and finally sanctioned and established by law. About the year 1164, another royal court of justice, distinct from the Court of Exchequer, arose out of it, the members of which, however, were the same as those composing the Court of Exchequer. The kings lent their assistance to this change, because it benefited their revenues. At this period were established _writs of chancery_, which gave to purchasers the right to apply at once to the royal justice, without previously passing the subordinate courts of justice. Soon the ignorance of the freeholders, who composed the county-courts, necessitated the same extension of the royal justice there also, and, in the reign of Henry I., _itinerant justices_ were sent into the counties, in order to administer there in the same way as was done by the Court of Exchequer. This institution was in full vigour only during the reign of Henry II. In this way the predominant influence of the king, in judicial order, was established; this was a powerful instrument in producing centralization and unity, and yet, as the royal judges only interposed their services as supplementary to the institution of the jury, and did not substitute them for it, for questions of fact and questions of right remained distinct,--the germ of free institutions, that existed in the judicial order, was not entirely destroyed. {298} Functions Of The National Assembly. A king invested with such powerful resources could with difficulty be restrained by an irregular assembly; accordingly the government of the Norman kings was almost always arbitrary and despotic. Persons and property were never in security; the laws, taxes, and judicial sentences were almost always merely an expression of the royal will.
