Charles Evans Hughes, Miller v. Wilson — Opinion of the Court
“ It is manifestly impossible to say that the mere fact that the statute of California provides for an eight-hour day, or a maximum of forty-eight hours a week, instead of ten hours a day, or fifty-four hours a week, takes the case out of the domain of legislative discretion. This is not to imply that a limitation of the hours of labor of women might not be pushed to a wholly indefensible extreme, but there is no ground for the conclusion here that the limit of the reasonable exertion of protective authority has been overstepped. ”
