Ainsa v. New Mexico & Arizona R. Co., 175 U.S. 76 (1899)
Ainsa v. New Mexico and Arizona Railroad Company
Submitted March 8, 16, 1897
Decided October 13, 1899
175 U.S. 76
Since the Act of Congress of March 3, 1891, c. 639, establishing the Court of Private Land Claims, the courts of the Territory of Arizona have jurisdiction, as between private parties, to determine whether a title under a Mexican grant, which has not been confirmed or rejected by, and is not pending before, Congress, and which is asserted to have been complete and perfect by the law prevailing in New Mexico before the cession of the country to the United States, was complete and perfect before the cession.
The case is stated in the opinion.
