Minneapolis, St. Paul & Sault Ste. Marie Railway Co. v. Popplar

Background

An administrator for the family brought a wrongful-death claim after a brakeman was killed on September 6, 1909 while uncoupling a car that was being “kicked” to a siding. The worker tried to pull the coupling pin with a lifter without success, then stepped between two cars moving about four miles per hour to uncouple by hand and was run over and killed. The family claimed the railroad violated the Federal Safety Appliance Act because the coupler worked with difficulty; the railroad pointed to a company rule forbidding going between moving cars and argued the worker was at fault. A jury found for the family, and the state supreme court affirmed the judgment.

Reasoning

The key question was whether the federal Safety Appliance Act changed who could raise worker-fault defenses or otherwise removed state-law negligence questions. The Court explained the Act only sets a specific duty for railroads to have approved couplers; it does not eliminate the defense that a worker was partly at fault. The Court also said the state court’s decision did not require construing the federal statute and that other questions about employer duty and employee negligence are governed by state law and common-law principles except where the federal law speaks directly.

Real world impact

The ruling means families can pursue wrongful-death claims even when employers cite safety rules, and juries may decide whether an emergency excused a worker’s disobedience. It keeps the Safety Appliance Act’s scope narrow: it focuses on equipment requirements, not on replacing state negligence rules. The judgment was affirmed on these facts and does not change the general role of state law in deciding employer-employee negligence disputes.
