What it's about

The Supreme Court agreed with the lower court that the Locomotive Inspection Act bars those claims because they fall within federal regulation of locomotive equipment.

The Court used an earlier Supreme Court decision, Napier, to define the Locomotive Inspection Act’s reach over locomotive equipment.

Question presented

Did Congress intend the federal railroad safety acts to preempt state-law-based tort lawsuits?

What the Court decided

Holding

Petitioners’ state-law design-defect and failure-to-warn claims fall within the field of locomotive equipment regulation pre-empted by the LIA, as that field was defined in Napier v. Atlantic Coast Line R. Co., 272 U. S. 605. Pp. 2 − 11. 620 F. 3d 392, affirmed.

Result
Affirmed

The Court's reasoning

The Court relied on Napier, an earlier Supreme Court decision that defined the Locomotive Inspection Act’s reach over locomotive equipment. It concluded that the estate’s design and warning claims fell within that federally regulated area, so federal law bars them.

Did Congress expressly bar these state-law claims?
No. The Court based its decision on the federal law’s reach over locomotive-equipment regulation, rather than an express ban on state claims.
