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.
