David Davis, De Haro v. United States — Opinion of the Court
“ But here, in the case of a private individual granting the right to use the most valuable property at his own pleasure, it would be an evident absurdity to put such license in the form of a solemn document, clothe it with legal formalities, give notice thereof to the world by registration, that he has done what simply allowed another to use his estate until he chooses to put him off, it may be, the next hour; for a power of revocation at will gives no fixed time to the licensee. ”
