No. 20-807October Term 2020Decided Apr 28, 2022

- What it's about
A Union Pacific conductor sued after he slipped on oil on a locomotive walkway in a rail yard. The case centers on whether the locomotive was "in use" at the time of the accident, which would determine whether the Locomotive Inspection Act's safety rules applied.
Question presented
1. Whether a locomotive is in use on a railroad's line and subject to the LIA and its safety regulations when its train makes a temporary stop in a railyard as part of its unitary journey in interstate commerce, or whether such use does not resume until the locomotive has left the yard as part of a fully assembled train, as held by the Seventh Circuit below, contrary to the decisions of this Court and other circuits. 2. Whether the FELA allows a jury determination on the issue of foreseeability of harm from oil on a locomotive passageway when the railroad failed to conduct federally mandated daily safety inspections intended to discover and cure such hazards in the days before the injury incident, contrary to the longstanding decisions of this Court.

Briefing
What it's about
A Union Pacific conductor says he slipped on oil on a locomotive walkway in a rail yard and was injured. The Supreme Court is being asked whether the locomotive was still "in use" during that temporary stop and whether missed daily safety inspections let a jury weigh whether the harm was foreseeable.
Vote
The case is pending, and oral argument has not been scheduled. LeDure argues the locomotive remained in use during a temporary yard stop, while Union Pacific relies on the Seventh Circuit's view that it was not in use then.
Impact
The answer could shape when federal locomotive safety rules apply in rail yards and when injured workers get to present negligence claims to a jury. For example, it could affect a conductor hurt while checking equipment during a brief stop in a yard.
What's next
Watch for oral argument or another scheduling move from the Court. No decision window is available yet.
What is the main dispute in LeDure v. Union Pacific Railroad Co.?
The Court is being asked whether a locomotive in a rail yard during a temporary stop is still "in use" under federal safety rules. It is also being asked whether alleged missed daily inspections let a jury assess foreseeability.
Why could this case matter beyond one worker's injury?
It could affect when railroads must follow locomotive safety rules in yards and when injured workers can get negligence claims before a jury. That matters in accidents involving slippery walkways and routine yard work.
What should readers watch for next in this case?
Watch for the Supreme Court to set oral argument or make another scheduling move. There is no decision window available yet.
