i8o The Period of Constitution Making both communal and private, have been discussed.1 We begin here with the situation as found in the early part of Henry I.'s reign. Private jurisdiction was increasing under the impulse of continental thought. Henry had attempted to correct the irregularities in the hundred and shire courts for which the sheriff had been largely response ble in his brother's time, and the sheriff, a royal officer had become the only presiding and constituting official in those courts. This last fact, taken in conjunction with a livelier conception of the king as the source of law and the masterful character of the post-Conquest sovereigns, leads one to look for an important change in the local courts, There are clear indications that the change was beginning under Henry I. There were meetings of the county court that re- quired such full attendance and entertained such a class of cases as make it clear that they were different from the ordinary meetings. Their composition was strikingly like that of the later itinerant justice courts; cases in which the king was specially concerned were tried there, and also cases between the vassals of different lords, such as on the continent would usually have been carried before a suzerain's court.2 When the king ordered this specially full attendance for doing this kind of business and the presiding sheriff was perhaps more emphatically the king's representative than wont, the shire court had, for the time, become a king's court. It is probable also that in the course of the reign itinerant justices were sent out with some regularity and that such courts were summoned to meet them.3 1 See Part II, § II, i. 2 Such cases might also be tried in the court of the defendant's lord. 3 Three instances of a king's court in the locality in the reign of William I. have been found. They were summoned by royal writ, justices presided and were distinctly in loco regis, the judgment was of the same force as that of the central court; and, while a baronial element and the county court were present, they were not essential to the court's authority, which was centrally derived and royal, not local.
