In effect, every measure of Parliament, of whatsoever nature and under whatsoever circumstances enacted, is "constitutional," in the sense that it is legally valid and enforceable. When an Englishman asserts of a measure that it is unconstitutional he means only that it is inconsistent with a previous enactment, an established usage, the principles of international law, or the commonly accepted standards of morality. Such a measure, if passed in due form by Parliament, becomes an integral part of the law of the land, and as such will be enforced by the courts. There is no means by which it may be rendered of no effect, save repeal by the same or a succeeding parliament. In England, as in European countries generally, the judicial tribunals are endowed with no power to pass upon the constitutional validity of legislative acts. Every such act is _ipso facto_ valid, whether it relates to the most trivial subject of ordinary legislation or to the organic arrangements of the state; and no person or body, aside from Parliament itself, possesses a right to override it or to set it aside.[58] [Footnote 58: For brief discussions of the general nature of the English constitution see A.
