George Sutherland, Cox v. Hart (260 U.S. 427) — Opinion of the Court
“ The effect of the substantive enactment was to forbid the entry of unsurveyed lands. But the law theretofore had been otherwise, and one purpose of the proviso evidently was to exclude from the operative effect of the new rule cases which might have arisen under the prior law; that is cases of persons who had taken possession of and undertaken to reclaim unsurveyed lands at a time when the law conferred the right to do so. Any such person, no less than one who acted subsequently, is within the words of the proviso. He is literally 'a person who has, prior to survey, taken possession,' etc. ”
