Article 470
ART. 470. Whenever the owner of the accessory thing has made the incorporation in bad faith, he shall lose the thing incorporated and shall have the obligation to indemnify the owner of the principal thing for the damages he may have suffered. If the one who has acted in bad faith is the owner of the principal thing, the owner of the accessory thing shall have a right to choose between the former paying him its value or that the thing belonging to him be separated, even though for this purpose it be necessary to destroy the principal thing; and in both cases, furthermore, there shall be indemnity for damages. If either one of the owners has made the incorporation with the knowledge and without the objection of the other, their respective rights shall be determined as though both acted in good faith. (379a)
