Rigid and Flexible Constitutions.
De Tocqueville had more particularly in mind another meaning which is commonly attached to the term "constitution." It is that of an instrument of special sanctity, distinct in character from all other laws; and alterable only by a peculiar process, differing to a greater or less extent from the ordinary forms of legislation. The special sanctity is, of course, a matter of sentiment incapable of exact definition, and it may be said to belong to the British Constitution quite as much as to some others. The peculiar process of amendment, on the other hand,—the separation of the so-called constituent and law-making powers,—upon which Mr. Bryce bases his division of constitutions into rigid and flexible,[2:2] has had a long history and been much discussed; but although the contrast between the two types is highly important, the creation of intermediate forms has made it less exact as a basis of classification. The later constitutions, and the more recent practice, have tended to obscure the distinction. A separation between the constituent and law-making powers does not, in fact, always exist in written constitutions. The Italian Statuto, for instance, which contains no provision for amendment, can be, and in fact has been, altered by the ordinary process of legislation;[3:1] and the same thing was true of the French Charter of 1830.[3:2] The last Spanish constitution omits all provision for amendment, but one may assume that if it lasts long enough to require amendment the changes will be made by ordinary legislative process.
From countries which can change their fundamental constitution by the ordinary process of legislation we pass by almost imperceptible degrees to those where the constitutional and law-making powers are in substantially different hands. Thus the procedure for changing the constitution in Prussia differs from that for the enactment of laws only by the requirement of two readings at an interval of twenty-one days. Here there is a difference legally perceptible between the methods of changing the constitution and other laws; but it may be remarked that a provision in the constitution to the effect that all laws should require two readings at an interval of twenty-one days, would not essentially change the nature of the constitution, and yet in theory it would make that constitution flexible instead of rigid. As it is, the fundamental laws are quite as much under the control of the legislature in Prussia as they are in England.[3:3] This is almost equally true of France; for although the changes in her constitution are made by the National Assembly, composed of the two chambers sitting together, yet the Assembly can meet only after the two chambers have passed a concurrent resolution to that effect; and in fact the chambers are in the habit of determining beforehand by separate votes the amendments which shall be submitted to the Assembly. So that in France, also, the constitution is virtually under the unrestricted control of the legislature.
The Distinction has Lost Practical Importance.
The separation of constituent and law-making powers has been rendered of much less practical importance in some countries not only by making the process of amending the constitution more simple, but also by making the enactment of laws more complex. In Switzerland, for example, changes in the Constitution of 1848 required a popular vote, while changes in the laws did not; but after the referendum on ordinary laws was introduced in 1874, this distinction largely disappeared, and at the present day the differences between the methods of passing constitutional amendments and ordinary laws are comparatively slight. In the case of ordinary laws a popular vote is taken only on the petition of thirty thousand citizens or eight cantons, and the popular majority is decisive; whereas constitutional amendments must be submitted to the people whether a petition is presented or not, and for their ratification a majority vote in more than half the cantons as well as a majority in the Confederation as a whole is required.[4:1]
In those European countries where the difference in the procedure for changing constitutional and other laws is the most marked, the special formalities for the former consist in requiring more than a majority vote in the legislature, or that a general election shall take place before the amendment is finally adopted, or both. Now the last of those conditions is practically not unknown in England. There is a growing feeling that no fundamental or far-reaching change ought to be made unless, as a result of a general election fought on that issue, Parliament has received from the nation a mandate to make the change. Such a doctrine does not affect the law, but it does affect that body of customs which is a not less vital part of the British Constitution.
The classical distinction between constituent and law-making powers, and hence between rigid and flexible constitutions, has also been somewhat effaced by extending the requirement of a special procedure to the enactment of certain classes of ordinary law. Thus in the German Empire the only peculiar formality for amendments to the constitution is found in the provision that they are defeated by fourteen adverse votes in the Bundesrath.[5:1] This gives Prussia with her seventeen votes a veto upon them, but she has also a veto in the Bundesrath upon any measures affecting the army, the navy, customs-duties or excises.[5:2]
Growing Variety in Written Constitutions.
In the middle of the last century written constitutions in Europe were framed for the most part upon the same model and were much alike, so that a written constitution usually implied a definite type of limited monarchy, where the same class of matters were removed from the direct control of the legislature and placed, in theory at least, under special protection. But now written constitutions all over the world have come to differ a great deal, some of them being simpler, and others more comprehensive than of old. The constitutional laws of France, for example, provide only for the bare organisation of the public authorities, and can be amended virtually at will by the legislature; while the constitutions of Switzerland, Germany and the United States go into great detail, and that of the United States can be amended only with the greatest difficulty. The result is that the French constitution, although written and technically rigid, bears from the point of view of rigidity a far closer resemblance to the constitution of England than to that of the United States.
It would seem, therefore, that the distinction between constitutions which are flexible and those which are rigid, while valuable, has ceased to mark a contrast between widely separated groups; and that it might be well to regard the distinction as one of degree rather than of kind. From this aspect it may be said that of late years constitutions have tended on the whole to become more flexible; and at the same time there has been a tendency toward greater variations in flexibility, the constitutions of England and of Hungary standing at one end of the scale, and that of the United States at the other.
