VI THE SCOPE OF APPELLATE REVIEW One of the advantages of an institution which is in the stage of creation and growth, before it has been discovered, described, and pinioned by textbook writers into a scheme of their own imaginings, is the lack of definition of its objectives and the plasticity of the methods whereby it reaches its unguessed destination. The Privy Council, combining as it did in relation to colonial affairs political with legal functions and being manned from session to session by a different crew, is a striking and to the lawyer often provoking example of the uncertainties of growing things. The absence of any clearly formulated conception of the appellate function and of a consistent and commanding guidance is most obvious in the Council's failure to capitalize its strategic position to remake the moldy and inadequate conceptions of error jurisdiction. The last decades of the seventeenth century in England had seen the struggle over equity appeals x and the futile efforts to establish an adequate review of criminal causes, 2 but the King's Council was impervious to these currents, laying to its heart, apparently, the dictum of Lord Chief Justice Jeffreys, "It is practice that is the law." 3 More specifically, the Council, in the face of the intransigeance of colonial courts vis a vis the crown, in the face of the frequent and palpable lack of technical perfection in colonial practice, and even despite the fact that conciliar procedure itself was not bound by the shackles of common law error or certiorari procedure, nevertheless failed to take advantage of the opportunities offered it to remake the traditional role of the reviewing tribunal by adding to the powers of reversal the power of reforming the judgment. The circumstance that there came before the Council not only cases at common law but also decrees of chancery and sentences of vice-admiralty courts created a unique opportunity for a blending of remedies by a body which was not as a matter of law committed to the maintenance of precedents from any court. Nevertheless, only a few hesitant steps were taken in this direction, for the cursus curiae of the several English jurisdictions was given a respectful regard, and in general the Council proceeded as if it had been the 1 i Holdsworth, HEL, 372-75. 3 Rex v.
