Louis Brandeis, Leser v. Garnett — Opinion of the Court
“ The first contention is that the power of amendment conferred by the federal Constitution and sought to be exercise does not extend to this amendment because of its character. The argument is that so great an addition to the electorate, if made without the state's consent, destroys its autonomy as a political body. This amendment is in character and phraseology precisely similar to the Fifteenth. For each the same method of adoption was pursued. One cannot be valid and the other invalid. ”
