RICHARDSON
v.
AINSA, ADMINISTRATOR OF ELY.
No. 28.
Supreme Court of United States.
Argued November 2, 1910.
Decided November 14, 1910.
APPEAL FROM THE SUPREME COURT OF THE TERRITORY OF ARIZONA.
*290 Mr. S.L. Kingan for appellant, submitted.
*293 Mr. Joseph W. Lewis, with whom Mr. Frank H. Hereford and Mr. Selim M. Franklin were on the brief, for appellee.
*294 MR. JUSTICE HOLMES delivered the opinion of the court.
This is a suit to quiet title brought in 1887 by the appellee's intestate in the District Court of Arizona. The decision was in favor of the appellee, and this decision was affirmed by the Supreme Court of the Territory, *295 whereupon the defendant Richardson appealed to this court.
The appellee represents a title derived from a grant by the Mexican Government of land in the portion of Arizona afterwards acquired by the Gadsden Purchase, December 30, 1853. 10 Stat. 1031. At the time of the Gadsden Purchase this title was complete. The appellant claims through mesne conveyances from holders of patents issued by the United States in 1879 and 1880 under the homestead laws.
The first error assigned is that the District Court was without jurisdiction. That point already has been decided against the appellant in this very case under the name of Ainsa v. New Mexico & Arizona R.R. Co., No. 2, 175 U.S. 91, so that it is not open to him to urge it. United States v. Camou, 184 U.S. 572, 574. But it is proper to say that in our opinion the decision did not proceed upon a mistake of fact and is not inconsistent with the reasoning of the immediately preceding decision between the same parties, 175 U.S. 76, 86, although No. 2 was begun before and No. 1 after the passage of the act of March 3, 1891, c. 539, 26 Stat. 854, establishing a Court of Private Land Claims.
In 1892 the United States brought a suit against the present appellee in the Court of Private Land Claims, alleging that his claim was void, and that the United States had granted patents for portions of the land, praying that the title might be adjudicated, and, if valid, the boundaries established, excepting such parts as might have been disposed of by the United States. The appellee answered setting up title, and praying confirmation. Ultimately in pursuance of the decision of this court, Ely's Administrator v. United States, 171 U.S. 220, a decree was entered in his favor and a patent issued to him on October 29, 1906, specifying no exceptions other than one of "gold, silver, or quicksilver mines or minerals of the same." *296 The appellant however contends that by virtue of the above-mentioned statute of March 3, 1891, the effect of the appellee's appearance in the Court of Private Land Claims was to forfeit all portions of the land in controversy that had been patented by the United States, and to give the appellee in place of it a claim for not exceeding $1.25 per acre so patented against the United States. The contrary decision is the other error assigned.
Of course, the patents for homesteads issued in the name of the United States, on the facts that we have stated, were a mere usurpation and were void. The lands covered by them, whether reserved or not by the acts of July 22, 1854, c. 103, § 8, 10 Stat. 308; July 15, 1870, c. 292, 16 Stat. 304, were not public lands, but private property, which the Government was bound by the express terms of the Gadsden Treaty of December 30, 1853, to respect. The appellant's claim rests solely on an interpretation of §§ 8 and 14 of the above-mentioned act of 1891, that would cut down the performance of the treaty promise by the United States to at least to the narrowest limits consistent with good faith. We are of opinion that the different construction adopted by the court below, and also by the Acting Secretary of the Interior in Ely v. Magee, 34 L.D. 506, 512, is correct. After providing in § 6 for incomplete titles the act goes on in § 8 to deal with complete ones. Holders of claims under such titles, it says, "shall have the right (but shall not be bound) to apply to said court" for a confirmation of their title. Of course, this means that the title is recognized as good without the proceeding in court. Ainsa v. New Mexico & Arizona R.R. Co., 175 U.S. 76, 90.
The confirmation is granted, "excepting any part of such land that shall have been disposed of by the United States," and without prejudice to conflicting private interests. Then, in § 14 it is enacted that "if in any case it *297 shall appear that the lands or any part thereof decreed to any claimant under the provisions of this act shall have been sold or granted by the United States to any other person, such title from the United States to such other person shall remain valid, notwithstanding such decree," with a provision for a judgment in favor of the claimant against the United States for the proved value of such granted lands, not exceeding $1.25 per acre. If this were all there could be no question that the exception of lands granted by the United States was merely a condition attached to the decree of confirmation, and did not purport to affirm such grants if the claimant did not see fit to go into the Court of Private Land Claims.
But in § 8 there is a further provision by which the United States may proceed against the claimant, as it did against the appellee, on the ground that the title or boundaries are open to question, and therefore the court is to determine the matter, "but subject to all lawful rights adverse to such claimant or possessor, as between such claimant and possessor and any other claimant or possessor, and subject in this respect to all the provisions of this section applicable thereto." The appellant argues that this provision gives a wider meaning to § 14. He says that the words "if in any case" it shall appear that lands have been sold by the United States apply as well to a proceeding by the United States as to one where the claimant goes forward. He argues that so to apply them is just, in view of the supposedly unknown boundaries of the old Mexican grants and the policy of the United States in offering its public lands to settlers  that otherwise there is a suspended threat and possibility of a claimant turning up after many years and dispossessing those who had been encouraged by the United States to go upon the land. Botiller v. Dominguez, 130 U.S. 238. But the considerations mentioned in the case cited did not prevent the United States in the act of March 3, 1891, from leaving *298 the holders of perfected titles free not to present them to the court as they were required to do in earlier statutes. The good faith of the United States was pledged to respect the Mexican titles. It recognized in the act of 1891 that holders of such titles need not go into the Land Claims Court to get them confirmed, and we should be slow to suppose that it meant to make a doubt in the Department of Justice as to the validity of a perfect title a ground for cutting down what otherwise it was bound to protect and did by the statute leave intact. But for that unfounded doubt the appellee would have been secure in his rights, and could have turned the holders of the homestead patents off his land. United States v. Martinez, 184 U.S. 441, 445. The proceeding by the Government was a matter over which he had no control, and ought not to affect his rights. Looking at the words of § 14 more exactly they do not require the appellant's construction. "If in any case" means in any case before the court that the act established. And when the section goes on, "it shall appear that the lands or any part thereof decreed to any claimant under the provisions of this act shall have been sold," it is reasonable to suppose that it has reference to those cases in which a claimant is seeking a decree, that is to say, where the claimant is the plaintiff in the case. It is true that a petition by the United States may end in the same result, but the terms of the sentence and the duty of the Government concur in leading us to limit the words as we do. On the other hand, the consideration mentioned sufficiently shows that the claimant did not impair his position by praying for confirmation in his answer. The prayer merely expressed what would have happened without it by the force of law.
Judgment affirmed.
