Joseph McKenna, Wilson Cypress Company v. Del Pozo y Marcos…
“ It seeks to quiet the title of complainants to a tract of land commencing in a grant from Spain, depending for its completeness upon the treaty with Spain and laws of the United States, and the action under those laws by the officers of the Land Department of the United States, and it especially relies on those laws to defeat defendant's claim of title, and to have it removed as a cloud upon that asserted by complainants. Indeed, there is scarcely a contention of complainants which does not primarily or ultimately depend upon the laws of the United States. ”
