Law Courts 251 In the thirteenth century, the clerk by the sheriff was by the until the coming of the itinerant justices, he actually ap- peared before them accused, in the century after accusation and to the court, the justices submitted his to a jury obtained a verdict. This was not his trial, but if the verdict were guilty his property with its income for the king until his fortune in the bishop's court known. But the ecclesiastical trial became a farce. Compurgation was still used, an antiquated form of proof that, under the changed conditions, lost what little virtue it had ever possessed as a method of ascertaining the truth,1 It was especially useless when a clerk the com- purgators from his own order. The church might inflict severe punishments^ as life imprisonment; but such to have been seldom used. There were still, in the thirteenth century, valua- ble limitations to benefit of clergy: the privilege not been extended to the lower orders of the clergy, where clerical crime lay, but was confined to ordained clergy, monks, and nuns; the worst forms of treason were not within its operation; and, in the lighter offences, the mis- demeanours, clerks were dealt with as laymen. But canonists; had it been maintained, no deposed or degraded clerk would ever have been handed over to the lay power as a heretic or a forger of papa! bulls. As a general principle of law, Becket's theory about double punishment was condemned by Innocent III; the decree which condemns it is to this day part of the statute law of the Catholic church."—P, and M. i-t 455- 1 Besides its use in the ecclesiastical courts* computation continued in the old local courts, its^ strongest hold being in the boroughs. It is in- teresting that in London it was much affected by jury practice, with the result that compurgators were not to be chosen by the accused himself, nor were any of them to be related to him by blood or marriage; while on the other hand he might challenge them for reasonable cause. It could also be used in personal actions in the kingfs courts, and In real actions it was used in incidental questions, such as the denial of the summons by the tenant. Certain actions in which the defendant might have recourse to compurgation could be brought in the nineteenth century. But such actions were avoided; means had been provided for bringing others in their place. Computation was prohibited by statute in 1833. See Thayer* e^ pp. 25-28, 34.
