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. ”
