Chicago Junction Railway Co. v. King

Background

A railroad switch-man was injured at the Union Stock Yards in Chicago after cutting some cars from an interstate freight train. A coupler knuckle on one car was broken; the worker obtained a replacement knuckle and went between the cars to fit it. The train conductor ordered the train shoved back several city blocks to reach a planned repair spot, and a backward movement crushed the worker. The worker sued under the federal Safety Appliance Law. The case began in state court, was removed to the federal Circuit Court where the plaintiff won, and reached this Court on the claim that a constitutional issue gave jurisdiction.

Reasoning

The Court addressed whether the record showed the worker was so clearly contributorily negligent that the judge should have directed a verdict for the railroad. It explained that jurisdiction existed because the plaintiff’s cause of action was based on the federal Safety Appliance Law. But the contested issues required weighing the whole body of evidence, and this Court will not reexamine the entire record or redraw possible inferences. Instead the Court looks only for plain, clear error. Having reviewed the record and the Circuit Court of Appeals’ opinion, the Court found no such plain error and affirmed.

Real world impact

The decision means the high court will not substitute its own view of mixed factual evidence for the findings of lower courts. It confirms that claims tied to a federal statute like the Safety Appliance Law bring federal jurisdiction. Practically, appeals asking the Supreme Court to reweigh evidence will usually fail unless a plainly obvious legal mistake occurred.
