delivered the opinion of the court.
This is an action against the drawer and endorsers of two promissory notes. The answer alleges, that the defendant, James Hopkins, is the owner of a certain lot of ground in the city of New-Orleans, situated on Levee-street, between Bien-ville and Custom-house streets, that he holds, and his vendors have always held said property, under titles describing it as fronting on the river Mississippi, that the space between his lot and the river was designated on the original plan of the city, and on all plans subsequently made, as public property, in consequence of which he, Hopkins, was a front proprietor, and entitled to have and enjoy all the rights, privileges, and advantages of such a situation; that under a decree of the *329District Court of the United States for the Eastern District of Louisiana, rendered by consent of parties in the suit of the United States against the mayor, aldermen, and inhabitants of the city of New-Orleans, the space of ground between , i • r ° Levee-street and the river, between the lateral streets last mentioned, including the space in front of his, the respondent’s, lot,'was advertised for sale at public auction ; that said decree was made without any lawful authority, and all the proceedings under it were null and void ; that the respondent entered his protest against the sale, and notwithstanding his opposition and protest, the sale took place, and to prevent third persons from purchasing the space, he purchased the lot immediately in front of his property as before described ; that the two notes sued on were given by the respondent in part payment of the lots thus purchased by him. He pleads that the plaintiffs cannot maintain this action, because the court issuing the decree under which the property was sold was without jurisdiction, and that as the plaintiffs had no right, title, or interest in the property sold, the consideration on which the notes were given has totally failed; he prays that the notes sued on be cancelled by the order of the court, and that the other notes given by him in payment of said lot be delivered up to him. He also alleges, that by the said illegal conduct of the plaintiffs, in causing said public property to be sold, he has sustained damages to the amount of twenty thousand dollars, which he pleads in reconvention, and concludes with a prayer for general relief.
There was judgment for the plaintiffs, and the defendant has appealed.
The suit in which the property in front of the city was in litigation, was finally determined in the Supreme Court of the United States, in January term, 1836, and is reported in 10th Peters’s Reports, 733.
By a law of this state, passed on the 11th of March, 1836, the funds arising from this sale, in the event of a decision in favor of the present plaintiffs, against the United States, were made a part of Jthe city sinking fund, established by the 15th *330section of the act dividing the city into three municipalities, passed on the 8th March, 1836.

We doubt very much whether the doctrine of estoppel will apply in a contract of sale, between the vendor and vendee. This is a doctrine of legal policy only. Its application must necessarily depend on the circumstances of each case. 7 Wheaton’s Reports, 535, 547. As we decide this case on other principles, there is no necessity for considering the propriety of its application in the present instance.
Taking the case of the defendant as he has stated it himself, how stands his defence to this action 1
His lot is on Levee-street; it is held under titles describing it as fronting on the river Mississippi; the space between his lot and the river was designated in the original plan of the city, and all subsequent plans, as public property; he was a ^10nt P^P1'^01'» and entitled to all the rights, privileges and advantages of such a situation.
How can he complain of the alienation of this space. If, as says> ^ was Pu^c property, it has been lawfully alienated by the sovereign authorityfor the disposition of the proceeds of the sale by an act of the legislature, is equivalent t0 an or'§Pnal authority on the part of the state to make the alienation. If this space could be sold lawfully whenever the sovereign power should determine that its destination should be changed, what possible right can the front proprietors have to any indemnity from the state or those who stand in its stead. The change in this space, whenever the public interests should require it, is necessarily a condition resulting from the original destination; and the rights and C3 ° 7 © advantages of situation of the front proprietors, were neces*331sarily dependent on and subordinate to this condition. This they knew or were bound to know, when they acquired the property to which this supposed right or privilege of situation is attached. The right of the sovereign power to change the destination of this space of ground is as complete as the right of the defendant to enjoy his privileges in relation to it, until such change takes place.
T(ie public space or quai in vee^street, and ^'rWer^inthe city of New-Or-p¿nS’ofSthe city ’use^of1 the PuWib’e®nd h^" occupied as such, v^m-by an individual tl0n of’VRss,pace as a public place, was made by the er!am!Siheright ^¿'e^a^hange in it, whenever the public interest requires it d°“e,the sovereign power, and to this the rights of front subordinate.The true character of this space of ground under consideration, we think has been cónclusively settled in the dissenting opinion delivered by the present presiding judge of this court, in the case of Cucullu and De Armas, against the present plaintiffs, reported in 5 Louisiana Reports, 174, whicli was adopted as the basis of the judgment of the Supreme Court of the United States, in the suit in which the sale was made of which the defendant complains.
Judge Martin says, in his opinion, “I conclude, therefore, that the space under consideration, appearing by the plan of the city of New-Orleans to have been appropriated to the use of the public, and having been ever occupied as such, (although, in two instances, governors favored individuals with grants of part of it,) this court ought to say the locus in quo is part of a public place, hors de commerce, and cannot be claimed by an individual in a civil action.” On the subject of changing the destination of public places, the opinion of the COUrt Was unanimous.
The destination of this space as a public place, was made by the sovereign power when Louisiana was under the J ° r . dominion of the French monarchy ; it was changed by the sovereign authority of the state of Louisiana.'-, The right to make this change, whenever the interests of the public required it, is vested in the soverign power : to this right, that ‘ , ’ . , , oi the front proprietors is necessarily subordinate.
We consider that none of the rights or privileges of the defendant have been violated by the sale of the space in front of J . r ■ his estate, ana that there is no ground in law or equity for his withholding the price of it, and that, he has no claim for damages against the plaintiffs for their acts complained of.
*332We have not noticed in detail the several bills of exception (ak;en by the counsel of the defendant to the opinion of the judge refusing to admit the evidence offered. If the evidence went to prove any other matters than those admissible in evidence under the allegations of his petition, it was properly rejected; and if all his allegations were established, there would, under the view we have taken of the case, be no defence to the action of the plaintiffs.
It is, therefore, ordered, adjudged and decreed, that the judgment of the District Court be affirmed, with costs in both courts.
