This, as we have said, is a compromise; its leading idea is to fortify and draw closer the bonds of unity within the Reich on the basis of a new redistribution of territory according to economic and social interests and taking into account the wishes of the population. It is true that this has the value only of a programme without positive legislative force; nevertheless it has its importance; it presents the principle of a progressive revision of the territories of the states, a revision whose new unities would form organic divisions of the Reich such as would serve to a maximum degree the interest of the whole German people. The idea which should direct this territorial regrouping must be exclusively the interest of the German nation in its ensemble. The territorial status of the states no longer has as formerly a value absolute in itself, but is thereafter subjected to the condition that it assures in the largest measure possible the highest well-being of the Reich as a whole. There is in this undoubtedly a victory for the unitary idea. Frontiers, therefore, will be “mobile” and their modification will have to serve the development of the general welfare. It will have to be the Reich that will be called upon to preside over the question of new repartition of territories, because it alone is the holder of sovereignty in Germany, and because it alone is in position to maintain an equal balance between the varied and particular interests of the states. No territorial change whatsoever, whether a fusion, a separation, or the creation of a state, will be possible or operative no matter what conditions exist for its consummation, _without a law enacted by the Reich_. In addition--and this general rule must be followed every time that a change is envisaged which does not constitute an exception expressly provided for--such a law of the Reich must be enacted in the _form of a constitutional law_. This rule has three exceptions in which an ordinary law of the Reich suffices, provided that a certain number of other conditions are realized. (1) An ordinary law is sufficient when the change, the separation or the union of territories takes place _with the consent of the interested states_. This consent manifests itself in the form of a declaration of the governments of the states; for these governments by virtue of the constitution enjoy the confidence of the people, since they are supposed to be both democratic and republican; in which case a plebiscite is superfluous.
