ARTICLE 156
The Commonwealth may by law, without impairment of the right to compensation, and with a proper application of the regulations relating to expropriation, transfer to public ownership private business enterprises adapted for socialization. The Commonwealth itself, the States, or the municipalities may take part in the management of business enterprises and associations, or secure a dominating influence therein in any other way.
Furthermore, in case of urgent necessity the Commonwealth, if it is in the interest of collectivism, may combine by law business enterprises and associations on the basis of administrative autonomy, in order to insure the co-operation of all producing elements of the people, to give to employers and employees a share in the management, and to regulate the production, preparation, distribution, utilization and pecuniary valuation, as well as the import and export, of economic goods upon collectivistic principles.
The co-operative societies of producers and of consumers and associations thereof shall be incorporated, at their request and after consideration of their form of organization and peculiarities, into the system of collectivism.
