The same natural reluctance of those who owed suit to the local courts, to neglect their own affairs in order to perform public duties, which led to the demand for less frequent visits of the Justices of Assize, led also to an emphatic restatement of the old customary rules as to attendance at County Courts. Ordinary sessions were not to be held more frequently than once a month, nor was the sheriff to make his Tourn, or local circuit, throughout the various hundreds of his county more frequently than twice a year, namely at Easter and Michaelmas: and only at Michaelmas was he to hold view of frankpledge—one of the most important functions performed by him in the course of his circuit.[262] It was a more distinct concession to the feudal anti-centralizing spirit, that this royal view of frankpledge—for the sheriff acted as the king’s deputy—was prohibited from infringing any freeman’s franchises, whether such franchises had existed under Henry II. or had been subsequently acquired.[263] ----- Footnote 262: C. 42 of 1217. Footnote 263: _Ibid._ This seems to imply that all the aggressions since Henry’s reign, had not been on one side. The barons, in obtaining a promise to respect “franchises” acquired since 1189, tacitly admitted that they had been recently encroaching on royal prerogatives. By the Statute of Gloucester and the subsequent _quo warranto_ procedure Edward I. made a partially successful effort to redress the balance. ----- Two questions, destined to become of supreme importance in the future, have also left traces on this re-issue of the Charter:—on chapters 39 and 43 respectively. The former treats of the vexed question of a feudal tenant’s right to dispose of parts of his holding by gift or sale. There were two different methods of effecting this—by way of subinfeudation or by way of substitution: the tenant might create a new link in the feudal chain by granting part of his lands to a third party, who became his vassal as a result of the new grant; or he might endeavour to make the donee the direct vassal of his overlord, _quoad_ the land he had newly acquired. There was here a direct conflict of interest between overlord and tenant, which extended to both ways of conveying land. Freedom to sell it or give it away was clearly an advantage to the tenant; while the lord objected to a transaction which might thrust on him new vassals he did not desire, or might divide between two or more vassals the obligations formerly incumbent on one, making the incidence of feudal burdens uncertain and their enforcement more difficult. Chapter 39 contained a compromise. The tenant might part with a portion of his holding, provided the balance he reserved was sufficient to ensure full performance by himself of the obligations due to the lord. The original vassal thus remained primarily liable for the whole of the feudal obligations (whatever right of relief he might have against his donees
