after stating the case, delivered the opinion of the court.
The question presented for determination in this case relates, to the effect of proceedings taken under the act of March 3,. 1851, to ascertain and settle private land claims in California, upon the claims of parties holding concessions of lands in that State under the Spanish or the Mexican government. By the cession of California to the United States, the rights of the inhabitants to their property were not affected. They remained as before. Political jurisdiction and sovereignty over the territory and public property alone passed to the United States.
United States
v.
Percheman,
The authority and jurisdiction of Mexican officials terminated on the Yth of July, 1846. On that day the forces of the United States took possession of Monterey, the capital of California, and soon afterwards occupied the principal portions of the country, and the military occupation continued until after the treaty of peace. The political department of the government designated that day as the period when the conquest of California was complete and the authority of the officials of Mexico ceased. In this matter the judiciary follows the political department.
United States
v.
Yorba,
*81
The doctrine invoked by the defendants, that the laws of á conquered or ceded country, except so far as they may affect the political institutions of the new sovereign, remain in force after the conquest or cession until changed by him, does not-aid their defence. That doctrine has no application to laws authorizing the alienation of any portions of the public domain, or to officers charged under the former government with that power. No proceedings affecting the rights of the new sovereign over public property can be taken except in pursuance of his authority on the subject. The cases in the Supreme Court of California and in this court which reeognize as valid grants of lots in the Pueblo or City of San Francisco by alcaldes appointed or elected after the occupation of the country by the forces of the United States, do not militate against this view. Those officers were agents of the pueblo or city, and acted under its authority in the distribution of its municipal lands. They did not assume to alienate or affect the title to lands which was in the United States.

v.
Bourne,
It follows from what is thus said that it would be a sufficient answer to the contention of the defendants, that the grant under which they claim to have acquired a perfect title conferred none. The grantees were not invested with such title, and could not be, without an official delivery of possession under the Mexican government, and such delivery was not had, and could not be had, -after the cession of the country, except by American authorities acting under a law of Congress. But independently of this consideration, and assuming that the title under the grant was perfect, the obligation of the grantee was none the less to present his claim to the Board of Land Commissioners for examination. The ascertainment of existing claims was a matter of vital importance to the government in the execution of its policy respecting the public lands; and Congress might well declare that a failure to present a claim should be deemed an abandonment of it, and that the lands covered by it.should be considered a part of the .public' domain. Certain it is that a claimant presenting hie- *82 claim to the Board for examination and confirmation, in order that'he might subsequently acquire a patent from the government, is bound by the adjudication of the Board. After submitting his claim to its examination and judgment, he cannot afterwards be heard to say that in adjudicating upon his title the Board erred, or that the Land Department in determining the boundaries of his claim erred, in order that he may claim oritside of the survey and patent other lands which he considers covered by his grant. He cannot repudiate a jurisdiction to which he-has appealed; and the estoppel extends to parties claiming under him. Boyle v. Hinds, 2 Sawyer, 527; Cassidy v. Carr, 48 California, 339.
In determining claims under Mexican grants the Board of Land Commissioners' was required by the act under which it was created, to be governed by the treaty of Guadalupe Hidalgo, the law of nations, the laws, usages and customs of ■the government from which the claim was derived, the principles of equity, and the decisions of the Supreme Court of the United States, so far as they were applicable. And in
United States
v. Fossatt,
Trust relations respecting the property between the patentee and others may be enforced equally with such relations between him and others respecting any other property, but until. the patent is set aside or modified by proceedings taken at the instance of the government, all the questions necessarily involved in the determination of a claim to land under a Spanish or Mexican grant, and in establishing its boundaries, are concluded by it in all courts and proceedings, except as against parties claiming by superior title, such as would enable them to resist successfully any action of the government in disposing of the property. The confirmation takes effect, by relation, as of the date of the first proceeding commenced before the Land Commissioners; and an adjudication that at that date it was valid is also an adjudication that it was valid at the date it was made. And the patent which follows the confirmation and approved survey and is a matter of record, is itself evidence of the regularity of preliminary proceedings. As was said in
Beard
v. Federy,
It remains to consider two other positions taken by''the appellants; first, that the sale to Poli of the ex-mission of San Buenaventura was illegal and void, and hence that no
*84
title passed' to the patentee ’ on its confirmation; second, the want of any allegation in the complaint, or any evidence, in the proofs, that the plaintiffs were in possession of the premises when this suit was commenced. In support of the first position the appellants cite
