*46. What are "Constitutional" Laws?*--From this unrestricted competence of Parliament arise two highly important facts. One of them is that the distinction between "constitutional" laws, on the one hand, and ordinary statutes, on the other, is neither so obvious nor so essential as under most governmental systems. The concept, (p. 046) even, of constitutional law has developed but slowly among the English, and the phrase is as yet seldom employed in legal discussion. In the United States constitutional amendments or addenda, in so far at least as they assume written form, emanate from sources and by processes different from those that obtain in the enactment of ordinary statutes. In most continental nations the constituent process is at least somewhat different from that employed in the enactment of simple laws. And these specially devised processes are designed to emphasize the essential differentiation of the product from the handiwork of the ordinary legislative bodies. In Great Britain, however, there is, as has appeared, no difference of process, and the distinction between the law of the constitution and ordinary statute law is not infrequently all but impossible to trace. If it is to be traced at all, it must be derived from the circumstances of enactment. Some measures, e.g., the Habeas Corpus Act, the Act of Settlement, and the Parliament Act of 1911, relate obviously to the most fundamental and enduring aspects of state. Others just as clearly have to do with ephemeral and purely legislative concerns. Precisely where the line should be drawn between the two no man can say. It is, in the opinion of Mr. Bryce, because of this obstacle primarily that no attempt has been made to reduce the English constitution to the form of a single fundamental enactment.[55] [Footnote 55: Studies in History and Jurisprudence, I., No. 3.]
