The judicial authority of such a sovereign, however, far from being a cause of expense, was, for a long time, a source of revenue to him. The persons who applied to him for justice were always willing to pay for it, and a present never failed to accompany a petition. After the authority of the sovereign, too, was thoroughly established, the person found guilty, over and above the satisfaction which he was obliged to make to the party, was like-wise forced to pay an amercement to the sovereign. He had given trouble, he had disturbed, he had broke the peace of his lord the king, and for those offences an amercement was thought due. In the Tartar governments of Asia, in the governments of Europe which were founded by the German and Scythian nations who overturned the Roman empire, the administration of justice was a considerable source of revenue, both to the sovereign, and to all the lesser chiefs or lords who exercised under him any particular jurisdiction, either over some particular tribe or clan, or over some particular territory or district. Originally, both the sovereign and the inferior chiefs used to exercise this jurisdiction in their own persons. Afterwards, they universally found it convenient to delegate it to some substitute, bailiff, or judge. This substitute, however, was still obliged to account to his principal or constituent for the profits of the jurisdiction. Whoever reads the instructions (They are to be found in Tyrol's History of England) which were given to the judges of the circuit in the time of Henry II will see clearly that those judges were a sort of itinerant factors, sent round the country for the purpose of levying certain branches of the king's revenue. In those days, the administration of justice not only afforded a certain revenue to the sovereign, but, to procure this revenue, seems to have been one of the principal advantages which he proposed to obtain by the administration of justice.
