In United States v. Title Ins. Co. (1924) 265 U.S. 472, the Supreme Court of the United States dealt with the claims of certain Indians to the right to occupy land which was the subject of a federally patented Mexican land grant. The Indians' right to occupancy was said to have existed under Mexican law and it was contended that it survived or continued after the patenting process, even though no such reservation was mentioned in the patent.
