Louisville & Nashville Railroad v. Mottley

Case brief summary

Facts

A couple had a contract giving them free lifetime train passes from a railroad in exchange for giving up injury claims, but the railroad later refused to renew the passes, citing a new federal law banning free passes.

Procedural history

The couple sued the railroad in federal court to enforce their contract. The railroad asked to dismiss the case. The judge refused and sided with the couple. The railroad appealed.

Issue

Did the federal trial court have the legal authority to hear this contract dispute even though both sides were from the same state and the federal law issue only came up because of the railroad's expected defense?

Holding

The federal trial court had no power to hear the case because the couple's lawsuit was really just about a contract, not federal law.

Reasoning

A case only belongs in federal court when the plaintiff's own claim depends on federal law, not when they guess the other side might raise a federal defense.

Opinions

Majority (Moody): A case only belongs in federal court based on federal law if the plaintiff's own claim depends on federal law, not an anticipated defense, so the case must be dismissed.
