"Second, the 1985 Heritage Act strictly prohibits any commercial use of historical heritage objects."
According to Odyssey's Spanish attorney, there is no law in Spain that prohibits the sale of historical artifacts.

In 2003 the Ministry of Culture of Spain signed an agreement with Sea Hunt for the Spanish military frigates Juno and Galga. The article tenth of the agreement said textually:
All the extracted movable objects are of the Spanish state, of public domain and they won't be trade object.
For the interested I can send the text of the agreement.
