Law Courts 189 the second place, the theory that part of the jurisdiction was exercised by royal grant, and part by manorial right, was so emphasised that it soon became an established principle. This principle resulted hi a distinction between courts that must next be examined, Private courts had been quick to adopt the new royal procedure of jury presentment and trial, though the lim- ited number of suitors on some manors interfered with this. For private courts in England were, for the most part, manor courts.* A distinction began to be made in the judicial work which the lord did in these courts. He might be doing work analogous to that of the sheriff in his tourn, if by grant or prescription it had come to him. But this was criminal jurisdiction and view of frankpledge; it was, according to the view we have just noticed, a strict regality and could only be carried on under royal commission. Hence a court which did this was a royal court, a court of record; it must be sharply distinguished from a court which the lord held as of his own right, which he held because he had tenants. A new and distinguishing name, that of Leet9 was applied to it. This name, whose earlier history is very obscure, was probably first used in this connection in the reign of Edward I. From that time, we hear of Leets, the adjec- tive use of the word, as in Court Leet, not appearing until well into modern times. Here, then, was one part of the old, private jurisdiction, modified in its content and procedure by innovations from the king's courts, and finally taken up into, and made a part of, the royal judi- cial system; the lord's steward who conducted this court now conducted it as a royal officer. Thus it passes out 1 The courts of great honours, the feudal courts made up of vassals, had always been less important in England than on the continent; and now they were practically extinct, not only through the invasion of the royal courts and the limitations placed upon grants of justice, but through an important series of legislative acts of Edward L which checked subia- feudation and tended to break down the feudal hierarchy. A careful study should be made of documents 39, 40, 42, and 45 in A. and S.
