The Royal Court had grown substantially and was not always presided over by the King. To avoid court agents from having too much discretionary power, there was a systematic procedure for bringing cases to the Royal Court. First, a plaintiff had to apply to the King's Chancery for a standardized writ into which the cause had to fit. The plaintiff had to pay a fee and provide a surety that the plea was brought in good faith. The progress of the suit was controlled at crucial points by precisely formulated writs to the sheriff, instructing him for instance, to put the disputed property under royal protection pending a decision, to impanel an assize and have it view the property in advance of the justices' arrival, to ascertain a point of fact material to the plea, or to summon a 'warrantor' to support a claim by the defendant. The Royal Court kept a record on its cases on parchment kept rolled up: its "rolls". The oldest roll of 1194 is almost completely comprised of land cases. Anyone could appoint an agent, an "attorney", to appear in court on his behalf, it being assumed that the principal could not be present. The principal was then bound by the actions of his agent. The common law system became committed to the "adversary system" with the parties struggling judicially against each other. The Royal Court took jurisdiction over issues of whether certain land was civil or ecclesiastical [assize utrum], and therefore whether the land owed services or payment to the Crown or not. It also heard issues of disturbance of advowson, a complex of rights to income from a church and to the selection of a parson for the church [assize of darrein [last] presentment]. Many churches had been built by a lord on his manor for his villeins. The lord had then appointed a parson and provided for his upkeep out of the income of the church. In later times, the lord's chosen parson was formally appointed by the bishop. By the 1100s, many lords had given their advowsons to abbeys. As before, the land of any person who had been outlawed or convicted of a felony escheated to his lord. His moveable goods and chattels became the King's. The manor court heard cases which arose out of the unfree tenures of the lord's peasantry.
