The Constitution does not clearly choose between these three different methods of applying the principles of collective economy in the large sense of the word. It declares all three possible and leaves to the ordinary legislature, whenever it is desirable to regulate an industry in the general interest, the task of choosing the bearing it wishes to give such regulations and the régime to which it wishes to subject the industry in question. (1) In effect, according to the terms of Article 156 of the Constitution, the Reich may transfer private business enterprises to public ownership, that is to say, take over the property for the Reich, the States, or for the municipalities. (2) The Reich may participate itself or have the States or the municipalities participate in the administration of these enterprises, or may secure for itself in some other manner a decisive influence in these enterprises. (3) Or, finally, without taking to itself all or part of these enterprises the Reich may regulate, on the basis of autonomy and according to the principles of collective economy, the production and the distribution of wealth. In this last case the Constitution specifies that the business enterprises which are made subject to a nationalization measure, shall form “an autonomous body” (Selbstverwaltungskörper). This is a new form in public law. The “autonomous body” is somewhat analogous to ordinary public corporations. It administers itself with the organs necessary for it. It enjoys great independence, but it is nevertheless subject to supervision by the State. Article 156, par. 2, of the Constitution specifies that when legislation subjects a given industry to the system of nationalization and organizes the autonomous body it must constitute the administrative organs of this body in such a way that there shall be insured the co-operation of all the producing elements of the people, and that the salaried employés and wage-earners participate in administration and that the production and distribution satisfy first of all the interests of the commonwealth.
