Article 51: Right of property
The State recognizes and guarantees the right of property. Property has a social function and implies obligations. All persons have the right to the full use, enjoyment, and disposal of their assets.
1. No one may be deprived of his property, unless for a justified cause of public utility or social interest, previous payment of its just value determined by an agreement between the parties or the ruling of the appropriate court, in accordance with that established by law. In the case of the declaration of a State of Emergency or of Defense, the compensation may not be made previously.
