Administrative Law shall not be construed but upon an ethical approach to the human being and their purposes. This is the personalist approach.
Hereinafter, and carefully not confusing the extent of this approach, there is another component upon which much has been written, but not in great detail, which is the solidarity principle, which could be deemed a value, a virtue, an ethical principle or a
general principle of law, or, in any case, as a part of contracts and torts law, among other issues.
The question that this paper addresses is whether the principle of solidarity can be deemed a general principle of law and, more precisely, of Administrative Law, and whether it is vested with another treat that may have legal relevance.
