A certain uniformity of result was thus secured. American law, in its substantial framework, was not allowed to vary from English law in any case where agreement was reasonably practicable. There was a central power at London ever ready to enforce the charter rule. The colonial courts, if their judgments were to stand, must proceed in conformity to the British constitution. Justice must be administered by due course of law, and to find out what that due course was the judges were forced to study the English law-books. When Blackstone's Commentaries were first published, more copies were sold in America than in England.[Footnote: "Two Centuries' Growth of American Law," 20.] The colonial bench was weaker than the colonial bar. Judicial station was at first always, and later often, a mere incident of political office. When judges were appointed whose functions were wholly judicial, their selection was largely dictated by political considerations or executive favor. Few of them were really learned in the law. Of the bar many were. That of Massachusetts did not conceal its disapprobation when Lieutenant-Governor Hutchinson, although he had never been a member of it, was appointed Chief Justice in 1760. None of the judges of the first Superior Court in that colony were lawyers.[Footnote: Winsor, "Narrative and Critical History of America," V, 166.] In some of the others the Governor was the Chancellor, and in Maryland he was at one time the Chief Justice also.[Footnote: Steiner, "Maryland's First Courts," Reports of American Historical Association for 1901, 211; Osgood, "The American Colonies in the Seventeenth Century," I, Chap. II; II, Chap. XII.] In several the judges were appointed during the king's pleasure, and the Governor removed them at his discretion, without any notice or hearing.[Footnote: Bancroft, "History of the United States," II, 279. A notable instance of a removal in consequence in part, at least, of a decision as to the royal prerogative, not relished by the Governor, was the case of Chief Justice Lewis Morris of New York, in 1733. Documents relating to the Colonial History of New York, V, 948; VI, 4, 8, 951.] In those colonies which were provided by charter with a Court of Assistants, this body soon came to act as a judicial court. This took place in the colony of Massachusetts Bay as soon as the seat of the company's government was transferred from England to America, and took place as a matter of course. Divisional courts were frequently held by part of the assistants, with original jurisdiction of minor causes, and all sat semi-annually, or oftener, to try larger ones and hear appeals.[Footnote: Noble, "Records of the Court of Assistants of Massachusetts Bay," I, Preface; Publications of the Colonial Society of Massachusetts, III, 317.]
