188 The Period of Constitution Making ily less. And when the kings began to reflect upon the amount of criminal jurisdiction which some individuals already held, they did not critically study the past in order to understand the matter; they came to the con- clusion that, while there might be a kind of civil and petty criminal justice that went with the possession of a manor, this higher kind could never have been lawfully acquired except by definite royal grant.1 That this distinction was not clear at the time of the Conquest, nor for long after, it is hardly necessary to state. But it led directly to an act of Edward I. which had a profound effect upon the later history of private courts. In 1278, he issued the Writ Quo Warranto, which demanded by "what warrant" those who were exer- cising what he was pleased to consider regalian rights were doing so.2 It was assumed that, if they could not show a written grant from the king, the only means of acquiring such rights in Edward's time, they were to be deprived of them. This roused such protest that Edward abated his demand; he may possibly have foreseen the necessity of this from the first. Those who could show an unbroken exercise of these rights from the coronation of Richard I, were allowed to retain them. But two important things were accomplished. In the first place, any further ac- quisition of such rights was out of the question; and, mindful of the possibilities of forfeiture and deprivation which a powerful monarchy always possessed, it is easy to see that the exercise of high judicial power by private individuals would, at no distant time, pass away. In 1 On the origin of private jurisdiction, see above, pp. 38-41, 77, 78, 105. 3 In 1274 Edward had sent commissioners throughout the country to collect information about the franchises. This was recorded in what are known as the Hundred Rolls, because it was gathered from hundred to hundred—an interesting parallel to the gathering and recording of the Domesday material. Edward then spent three years in looking the material over and deciding what use he would make of it. His decision, embodied in the Writ Quo Warranto, is in the preamble to the Statute of Gloucester. The barons' pleas or replies to the writ are contained in the Placita de Quo Warranto. This was Edward's first important governmental meas- ure and shows how necessary he thought it was to check the growing feudal assumptions.
