The aim of its whole arrangement was to ensure the maintenance of peace, and therefore everybody was bound on entering the tithing to swear, not only that he would keep the peace, but that he would conceal nothing which might concern the peace[791]. It is natural that such a meeting as that held for the view of frank-pledge should begin to assume police duties and a certain criminal jurisdiction. Mr. Maitland has shown how, by its intimate connexion with the sheriff's tourn, the institution of frank-pledge was made to serve the purpose of communal accusation in the time of Henry II. The Assize of Clarendon (1166) gave the impulse in regard to the Sheriff's Court, and private lords followed speedily on the same line, although they could not copy the pattern in all its details, and the system of double presentment described by Britton and Fleta proved too cumbersome for their small courts with only a few freeholders on them. In any case the jurisdiction of the Court Leet is practically formed in the twelfth century, and the Quo Warranto inquiries of the thirteenth only bring out its distinctions more clearly[792]. [Court baron and customary court.] The questions as to the opposition between Court Baron and Customary Court are more intricate and more important. Mr. Maitland has collected a good deal of evidence to prove that the division did not exist originally, and that we have before us in the thirteenth century only one strictly manorial court, the 'halimotum.' I may say, that I came to the same conclusion myself in the Russian edition of the present work quite independently of his argument. Indeed a somewhat intimate acquaintance with the early Court Rolls must necessarily lead to this doctrine. If some distinctions are made, they touch upon a difference between ordinary meetings and those which were held under exceptional circumstances and attended by a greater number of suitors than usual. The expression 'libera curia' which meets us sometimes in the documents is an exact parallel with that of 'free gallows,' and means a court held freely by the lord and not a court of free men. Mr. Maitland adds, that he has found mention of a court of villains and one of knights, but that he never came across a court of barons in the sense given in later jurisprudence to the term 'Court Baron.' Here I must put in a trifling qualification which does not affect his main position in the least. The Introduction to the Selden Society's second volume, which is our greatest authority on this subject, mentions a case when the halimot was actually divided on the principle laid down by Coke and later lawyers generally. I mean the case of Steyning, where the Abbot holds a separate court for free tenants and another for his villains. The instance belongs to the time of the Edwards, but it is marked as an innovation and a bad one[793]. It shows, however, that the separation of the courts was beginning to set in. The Steyning case is not quite an isolated one.
