Summary

Charles Evans Hughes Borax Consolidated v. City of Los Angeles…

In determining the limit of the federal grant, we perceive no justification for taking neap high tides, or the mean of those tides, as the boundary between upland and tideland, and for thus excluding from the shore the land which is actually covered by the tides most of the time. In order to include the land that is thus covered, it is necessary to take the mean high-tide line which, as the Court of Appeals said, is neither the spring tide nor the neap tide, but a mean of all the high tides.

Charles Evans Hughes Borax Consolidated v. City of Los Angeles…

Was it upland, which the United States could patent, or tideland, which it could not? Such a controversy as to title is appropriately one for judicial decision upon evidence, and we find no ground for the conclusion that it has been committed to the determination of administrative officers.
Petitioners urge a distinction in that at the time of the survey no private right in the property had yet attached and the question lay between the federal government and the state of California. But the distinction is immaterial. If tideland, the title of the state was complete on admission to the Union.

Charles Evans Hughes Borax Consolidated v. City of Los Angeles…

The question before us is not as to the general authority of the Land Department to make surveys, but as to its authority to make a survey, as a basis for a patent, which would preclude the state or its grantee from showing in an appropriate judicial proceeding that the survey was inaccurate and hence that the patent embraced land which the United States had no power to convey.
