Felix Frankfurter,
Quicksall v. Michigan — Opinion of the Court
“ And whenever said judge shall have reason to doubt the truth of such plea of guilty, it shall be his duty to vacate the same, direct a plea of not guilty to be entered and order a trial of the issue thus formed.'↑ Assertions now made concerning irregularities in the hearing on the degree of the crime were not urged before the Michigan courts. They cannot be considered here for the first time, even as to their supposed bearing on the right to counsel. ”
