although an original writ was not current out of the realm, a royal mandate was nevertheless effective if King's business was involved. 53 This amounted to no more than a generalized assertion of prerogative, but within a few decades the matter was more precisely grounded as a rule of law, when it was judicially laid down that even in places where originals did not run, if such places were in the King's power a royal mandate must be obeyed." 4 The political and administrative implications of this are obvious. The contemporaneous use of devices for review of judgments no doubt contributed toward settling the übiquity of certain types of royal process, since the review jurisdiction was a species of evoking pleas coram rege, although after judgment. It is distinguished further by the fact that the practice of review was developed from theories peculiar to itself. The theory which touched the dominions was in point of jurisdiction derived from feudal law which vested in an overlord appeals for default of justice, and which conceived as possible progressive recourse up the feudal ladder to the suzerain himself. 55 The successful planting in England of this conception of progressive appeal was frustrated by the royal claim to an immediate prerogative over all cases of unjust judgment or default of justice. 56 In consequence, the appeal per saltum had become the norm before the twelfth century was out, 57 although it was not until the Statute of Marlborough that the principle was irrevocably settled. 58 The appeal procedure for unjust judgment which the Normans had brought to England was neither a procedure for the correction of errors nor a review of the merits, of a controversy inter partes. As the word appeal in its medieval connotation suggests, it was an accusatory proceeding at the instance of a party aggrieved by a judgment, against the courtkeeper or body of judgment finders. 59 It had this in common with appeals of felony, that an issue of perjury 53 3 Sayles, op. cit., xlvi et seq. 54 YB 19 Edw. 11l (R.S.), 337- 55 On this, cf. Mitteis, Lehnrecht und Staatsgewalt (1933) 298, 316, 538 et seq.; Fournier, Essai sur I'histoire du droit d'appel (1881), 140 et seq.; Adams, Council and Courts in Anglo- Norman England (1926), 161 et seq. 56 Leges Henrici, 10.1; 59, 19. Cf. ibid., 33, ia, and Glanville, De legihus xii, 7. The false or unjust judgment is broadly a species of default of justice, but Leges Henrici appears to distinguish between them {cf. 33, 2; 33, 3a) not because the difference was vital to found jurisdiction, but chiefly because different procedures were involved, arid the sanction falls in the first case on the body of judgment finders and in the latter may be confined to the court keeper (ibid., 7, 6). 57 Adams, op. cit., 164 n. 20. In Italy in the eleventh century a similar rule of immediate appeal to the Emperor obtained (Mittcis, Der Stoat des Hohen Mittelalters [1940], 163). 58 c. 19, 1 Statutes of the Realm (R.C.), 24. 59 The Normans appear to have taken over the Frankish procedure for impeaching judgments (cf. 2 Brunner, Deutsche Rechtsgeschichte [2d ed.], 473 et seq.). Certain incidents, such as battle, were embroidery put upon it by feudal society. It is to be noted that the Anglo-Saxons used a procedure for impeaching judgments which bore certain resemblances to the original Frankish institution (2 Liebermann, Gesetze der Angelsachsen [1906], s.v. Urteilschelte).
