Even more important is the evidence which we get from this document of a royal system of local justice acting in conjunction with the old system of shire courts. The last half of the writ implies that there had arisen thus early the questions of disputed jurisdiction, of methods of trial, and of attendance at courts, with which we are familiar a few generations later in the history of English law. Distinctly implied is a conflict between a royal jurisdiction on one side and a private baronial jurisdiction on the other, which is settled in favour of the lord's court, if the suit is between two of his own vassals; but if the disputants are vassals of two different lords, it is decided in favour of the king's,--that is, of the court held by the king's justice in the county, who may, indeed, be no more than the sheriff acting in this capacity. This would be in strict harmony with the ruling feudal law of the time. But when the suit comes on for trial in the county court, it is not to be tried by the old county court forms. It is not a case in the sheriffs county court, the people's county court, but one before the king's justice, and the royal, that is, Norman method of trial by duel is to be adopted. Finally, at the close of the writ, appears an effort to defend this local court system against the liberties and immunities of the feudal system, an attempt which easily succeeded in so far as it concerned the king's county courts, but failed in the case of the purely local courts.[21]
