But, except for those Latin countries which have copied it from the United States, the doctrine is almost entirely confined to the places where the Common Law prevails,[7:2] for elsewhere the same definition of law does not obtain. In accordance with the French interpretation of the theory of the separation of powers, it is the general rule on the continent of Europe that the ordinary courts administer only private law between private citizens, and that questions affecting the rights and duties of public officials are withdrawn from their jurisdiction. Such questions are now usually, though not universally, submitted to special tribunals known as administrative courts. The rules administered by these tribunals are laws, but they form a distinct and separate branch of the law from that applied by the ordinary courts. On the continent, therefore, a constitution may or may not be properly regarded as a law, but even if it be so regarded it is not of necessity enforced by any court. On the contrary, if an ordinary court is not suffered to pass upon the legality of the actions of a policeman, it would be hardly rational that it should pass upon the validity of an act of the national legislature; and it would be even more irrational to intrust any such power to the administrative courts which are under the influence of the executive branch of the government.[8:1] [Sidenote: Legal Restraints on Power of Legislature are Rare.] The conception of a constitution as a law of superior obligation, which imposes legal restraints upon the action of the legislature, is really confined to a very few countries, chiefly to America and the English self-governing colonies.[8:2] In Europe it has no proper place, for whether a constitution in continental states be or be not regarded as a supreme law, no body of men has, as a rule, been intrusted with legal authority to enforce its provisions as against the legislature; and in England there is no law superior in obligation to an Act of Parliament. There can, indeed, be no doubt that the Acts of Union with Scotland and Ireland were intended to be, in part at least, forever binding, but as they created no authority with power either to enforce or to amend the Acts, the united Parliament assumed that, like its predecessors, it possessed unlimited sovereignty; and it has, in fact, altered material provisions in each of those statutes.[8:3] [Sidenote: Sources of the English Constitution.]
