The supreme court was the king and his council in Parliament. It heard the most important causes, important because they concern the king, or because they concern very great men (e.g.treason), or because they involve grave questions of public law, or because they are unprecedented. It has large, indefinite powers and provides new remedies for new wrongs. The office of great justiciar disappears and the chancellor becomes the head of the council. After the council were the royal courts of the King's Bench, Common Pleas, and the Exchequer, which had become separate, each with its own justices and records. The Court of Common Pleas had its own Chief Justice and usually met at Westminster. This disadvantaged the small farmer, who would have to travel to Westminster to present a case. The King's Council maintained a close connection with the Court of the King's Bench, which heard criminal cases and appeals from the Court of Common Pleas. It traveled with the King. There were many trespass cases so heard by it in the reign of Edward I. The King's Council did a great deal of justice, for the more part criminal justice. It was supported by the populace because it dealt promptly and summarily with rebellion or some scandalous acquittal of a notorious criminal by bribed or partial jurors, and thereby prevented anarchy. Its procedure was to send for the accused and compel him to answer upon oath written interrogatories. Affidavits were then sworn upon both sides. With written depositions before them, the Lords of the council, without any jury, acquit or convict. Fines and imprisonments were meted out to rioters, conspirators, bribers, and perjured jurors. No loss of life or limb occurred because there had been no jury. In criminal cases, witnesses acquainted with particular facts were added to the general assize of twelve men from each hundred and four men from each town. The assize then bifurcated into the grand jury of twelve to twenty-four men and the petty jury or jury of verdict of twelve men, which replaced ordeal, compurgation, and trial by combat as the method of finding the truth. The men of the petty jury as well as those of the grand jury were expected to know or to acquaint themselves with the facts of the cases. The men of the petty jury tended to be the same men who were on the grand jury.
