Roger B. Taney,
Fremont v. United States — Opinion of the Court
“ And the first point to be decided is, whether the grant vested in Alvarado any present and immediate interest; and, if it did, then, secondly, whether any thing done or omitted to be done by him, during the existence of the Mexican government in California, forfeited the interest he had acquired, and revested it in the government? For if, at the time the sovereignty of the country passed to the United States, any interest, legal or equitable, remained vested in Alvarado or his assigns, the United States are bound in good faith to uphold and protect it. ”
