Missouri Pacific Railway Co. v. Castle

Background

A man who said he was a Nebraska citizen sued a railroad that said it was a Missouri corporation after he was injured while working as a brakeman on a freight train in Nebraska. He sought damages under a 1907 Nebraska law that made railroads liable for employee injuries caused by co-workers and limited the defense of contributory negligence when the employee's fault was slight compared with the employer's gross fault. The railroad argued the law violated the Constitution by denying equal treatment, abridging its privileges as an out-of-state company, and conflicting with federal law about interstate commerce. The railroad also raised, belatedly, that it was effectively a Nebraska corporation and so diversity jurisdiction was lacking.

Reasoning

The Court relied on earlier decisions that allow states to impose liability on railroads for injuries caused by fellow employees and to modify the common-law rule about contributory negligence. It found no federal law taking away Nebraska's power to protect railroad employees in these circumstances and said the Safety Appliance Act did not invalidate the state rule here. The Court also rejected the late challenge that the company had become a domestic Nebraska corporation because the company had admitted it was a Missouri citizen in its answer.

Real world impact

The Court affirmed the judgment for the injured worker, meaning the Nebraska rule stands and injured railroad employees can recover under this state law despite some contributory fault. The ruling leaves open that federal law could govern in other situations, and it does not change outcomes where Congress has already acted.
