Solidarity as a constitutional principle

The Art. 2 Constitution establishs the principle of solidarity as an general principle of organization of the State. Nevertheless, at the sight of other constitutional articles we must to say that it presents an essentially economic content. Even so, to confine the constitutional solidarity principle's content to the strictly economic, that is, to a balanced distribution of the wealth between all the regions, it would be an erroneous interpretation. Indeed, the solidarity principle is a polyvalent principle. It is likewise a value of the constitutional order and, in like manner, it may be understood as a general clause that requires to meet the common interest and not only the own in the performance by the territorial bodies of its own scopes. We do not think that the content of this principle be unlimited, but it is true that the solidarity principle may be linked with some characteristic underlying principles of the federal or regional State such as the loyalism federal (the german Bundestreue) or the general obligation of collaboration between the State and the Autonomus Communities.
