The idea of a supreme authority exercising the function of setting aside acts of legislative bodies which it deemed inconsistent with a higher law was familiar to Americans from an early period of our colonial history.[Footnote: See Chap. I; Dicey, "Law of the Constitution," 152; "Two Centuries Growth of American Law," 12, 19.] The charter of each colony served the office of a constitution. The Lords of Trade and Plantations exercised the power of enforcing its observance. They did in effect what, as the colonies passed into independent States with written Constitutions, naturally became the function of their own courts of last resort. The Constitution, like the charter, was the supreme law of the land. Whatever statutes the legislature of a State might pass, it passed as the constitutional representative of the people of that State. It was not made their plenary representative. Every Constitution contained some provisions restricting the legislative power. If any particular legislative action transgressed these restrictions, it necessarily went beyond the authority of the body from which it emanated. The Judicial Committee of the Privy Council, which now exercises the functions formerly belonging to the Lords of Trade and Plantations, and is in fact the same body, deals in a similar way today with questions of a constitutional character. If one of the provinces included in the Dominion of Canada should in its local legislation infringe upon a field belonging to the Dominion Parliament, this committee can "humbly advise the king" that the act in question is for that reason void.[Footnote: In July, 1903, for instance, an Act of the Province of Ontario, entitled the "Lord's Day Profanation Act," was thus declared _ultra vires_.] The Revolution found the new-made States of the Union without this safeguard against a statute repugnant to a higher law. They had enjoyed as colonies the advantage which Burke declared was an ideal in government. "The supreme authority," he said, "ought to make its judicature, as it were, something exterior to the State." The supreme judicature for America had been in England. There was now no King in Council with power to set a statute aside forthwith by an executive order. But the other function of the King in Council, that of acting as a court of appeal from colonial judgments, had been simply transferred to new hands. The State into which the colony had been converted now exercised it for itself and through her judiciary.
