That the state has power to forbid such employment and to punish the forbidden employment when occurring in intrastate commerce, and also has like power in respect of interstate commerce so long as Congress does not legislate on the subject, goes without saying. But it is a different question whether such a state act can be made to bear the construction that a violation of it constitutes negligence per se or negligence at all under the Federal Employers' Liability Act. The Kentucky act, as we have set it out above, is a criminal act and imposes a graduated system of penalties.

For, if Congress have a constitutional power to regulate a particular subject, and they do actually regulate it in a given manner, and in a certain form, it cannot be that the state legislatures have a right to interfere, and, as it were, by way of complement to the legislation of Congress, to prescribe additional regulations, and what they may deem auxiliary provisions for the same purpose.

The California law provided that no minor under the age of 18 years should be employed between 10 o'clock in the evening and 5 o'clock in the morning, and the trial court charged that, if the jury believed from the evidence that the employment or permission to work at night hours contributed to his injuries, the plaintiff was not guilty of contributory negligence. This was held to be error because of the exclusive provisions of the Federal Employers' Liability Act.
