Law Courts 243 might be exerted to enforce the bishop's summons. William assumed that it was clear to every one what breaches of church law were. There is certainly no hint from his reign of "any immunity of from jurisdiction or temporal punishment.1* Simply, the old local courts no longer dealt with laymen's failures to their church obligations. Between the time of this ordinance and the famous controversy between Henry II. and Becket, the Jurisdic- tional claims of the church made a great advance. It was then that there took place in England what has aptly called the "reception of Gregorianism." This might easily be taken to mean too much, but the English church did become deeply and lastingly affected by the principles of the great pope; and such a change in so im- portant an element of the population necessarily touched the government, and that most markedly in the judiciary. The unknown author of the Leges Henrici Primi, writing under Henry L, said that all ordained clergy "are to be accused before their prelates for all crimes, both the great- est and the lesser." This writer borrowed so much from continental principle and practice that it is hard to tell how far this reflects English custom in his time. But there is reason to believe that it is not wholly contrary to fact, and it may safely be concluded that there was some attempt, in Henry L's reign, to accuse and try criminous clerks in the bishop's court. William's ordi- nance said nothing about criminous clerkss and he un- questionably intended, at the time of its issue, that they should be dealt with as they always had been in England; for it was clearly concerned with changing Anglo-Saxon and not Norman practice. But it should be noticed that there were three distinguishable parts in the criminal procedure: accusation, trial, and punishment. William had come from the continent and dealt with prelates who, for the most part, had had a continental training; and, apart from what this particular ordinance said or did not say, Maitland thinks
