Due-Process Clause

is a clause that precisely forbids a State licensing agency to lay bare its arbitrary action, or forbids State law from explicitly allowing it to act arbitrarily.

A license cannot be revoked because a man is red-headed or because he was divorced, except for a calling, if such there be, for which red-headedness or an unbroken marriage may have some rational bearing. If a State licensing agency lays bare its arbitrary action, or if the State law explicitly allows it to act arbitrarily, that is precisely the kind of State action which the Due Process Clause forbids.
