Further addressing the due process challenge, Roberts wrote that in absence of other constitutional restrictions, a state may both adopt an economic policy that can reasonably be said to promote public welfare and enforce such policy by appropriate legislation. Courts, however, have no authority to create such policy or to strike it down when it has been properly enacted by the legislature. He added, "With the wisdom of the policy adopted, with the adequacy or practicability of the law enacted to forward it, the courts are both incompetent and unauthorized to deal."
