by John Marshall Harlan, Lochner v. New York — Dissenting Opinion
“ Suppose the statute prohibited labor in bakery and confectionery establishments in excess of eighteen hours each day. No one, I take it, could dispute the power of the State to enact such a statute. But the statute [p72] before us does not embrace extreme or exceptional cases. It may be said to occupy a middle ground in respect of the hours of labor. What is the true ground for the State to take between legitimate protection, by legislation, of the public health and liberty of contract is not a question easily solved, nor one in respect of which there is or can be absolute certainty. ”
