William O. Douglas,
Boykin v. Alabama — Opinion of the Court
“ It was error, plain o the face of the record, for the trial judge to accept petitioner's guilty plea without an affirmative showing that it was intelligent and voluntary. That error, under Alabama procedure, was properly before the court below and considered explicitly by a majority of the justices and is properly before us on review.A plea of guilty is more than a confession which admits that the accused did various acts; it is itself a conviction; nothing remains but to give judgment and determine punishment. ”
