The itinerant justices gradually ceased to perform administrative duties on their journeys because landed society had objected to their intrusiveness. Edward I substituted regular visitations of Justices of Assize for the irregular journeys of the itinerant justices. Each one of four circuits had two Justices of Assize. From about 1299, these Justices of Assize heard cases of gaol delivery. Their jurisdiction expanded to include serious criminal cases and breach of the king's peace. One woman was indicted to every 9 men. 16% of the women who were indicted were convicted compared to 30% of the men. Breaches of the forest charter laws were determined by justices of the King's forest, parks, and chases, along with men of assize. Coroners' inquest procedures were delineated by statute and included describing in detail in the coroner's rolls every wound of a dead body, how many may be culpable, and people claiming to have found treasure who might be suspects. The precedent for punishment for treason was established by the conviction of a knight, David ab Gruffydd, who had turned traitor to the Welsh enemy, after fighting with Edward and being rewarded with land, during the conquest of Wales. He had plotted to kill the King. He was found guilty of treason by Parliament and condemned to be dragged at the heels of horses for being a traitor to his knightly vows, hanged by the neck for his murders, cut down before consciousness left him to have his entrails cut out for committing his crimes during the holy week of Easter, and his head cut off and his body divided into four parts for plotting against the King's life. The head was placed on the Tower of London and his body sections were placed in public view at various other locations in England. This came to be known as "hanging, drawing, and quartering". Prior to this the penalty had usually been imprisonment followed by ransom. The penalty for a woman of treason, e.g. killing her husband, who was her lord, was burning at the stake. Trial by combat is now limited to certain claims of enfeoffment of large land holding and is barred for land held in socage, burgage, or by marriage. (Trial by combat eventually fell into disuse, but was not abolished until 1819.) Assize is the usual manner of trial, but compurgation remains in the borough court long after it becomes obsolete in the royal courts. It came to be that defendants no longer request assizes but are automatically put to them.
