The Assizes
Henry therefore founded various assizes, known respectively as the assize of novel disseisin, of mort d'ancestor, and of darrein presentment. The most popular one became the assize of novel disseisin, which in Law French meant something close to the "assize of recent dispossession". Those who had been recently put out of their lands could recover the beneficial use of them by resort to this assize, which led to a then innovative method of trial. Twelve "sword-girt" knights of the locality were summoned to determine, upon their own knowledge, who was entitled to the property. This innovative method of proceeding, the origin of the civil petit jury at common law, was aimed at the chaos introduced into property rights by crusade and civil war.
Henry's true measure of cleverness, though, is on display in his innovations in criminal justice. Henry appointed "justices in eyre," the counterpart of circuit judges, to travel from town to town. When they arrived, they too called upon "sword-girt knights" to summon twenty four free men from the surrounding areas. These twenty-four free men were the first grand jury. They were called to report under oath any accusations of crime they were aware of in the community. In theory, then as now, the grand jury only brought accusations; it did not find guilt or innocence.
This new assize did away with the old form of trial known as "compurgation" in accusations brought by the grand jury. Under compurgation, an accused person who swore he didn't do the crime, and who found a sufficient number of his neighbours to swear that they believed him, was acquitted. Compurgation was no longer available in charges brought by the grand jury.
The trial available to the defendant remained the traditional trial by ordeal. Nevertheless, Henry did not put much faith in the results of the ordeal. The unfortunate felon who was convicted through the ordeal was, of course, executed. But even if the indicted culprit was acquitted in the ordeal, he was banished. In other words, the proceedings by the grand jury were the actual trial; everyone it accused was punished, and the community rid of the malefactor, one way or another.
