John Marshall Harlan II,
United Mine Workers of America…
“ The sole issue before us is whether the Illinois Supreme Court is forbidden to do so because the plan unduly impinges upon rights guaranteed to the Union's members by the Fourteenth Amendment. Since the finding that the union plan presents dangers to the public and legal profession is not an arbitrary one, and since the limitation upon union members is so slight, in view of the permissible alternatives still open to them, I would hold that there has been no denial of constitutional rights occasioned by Illinois' prohibition of the plan. ”
