Railroad Commission of the State of Mississippi v. Louisville & Nashville Railroad Company

Background

A Kentucky-based railroad company sued Mississippi officials and the State Railroad Commission after Mississippi chancery courts sought to enforce a 1908 state law that would stop certain interstate trains at particular places, ban the company from intrastate commerce in Mississippi, and impose heavy forfeitures and penalties. The railroad removed an earlier state suit to federal court and then filed in federal court to block any new state proceedings enforcing the 1908 law. The railroad alleged it was a Kentucky corporation and challenged the Mississippi statute as unconstitutional under several provisions of the Federal Constitution.

Reasoning

The core question was whether the federal court had power to hear the railroad’s case and whether the railroad’s allegations of Kentucky citizenship were sufficient. The Court reviewed the bill, the parties’ stipulations, and the procedural history. It concluded the federal court properly retained authority, that the bill’s statements about out‑of‑state corporate citizenship were not undermined by other historical allegations, and that the federal court was entitled to decide the constitutional claims. Because the lower court had resolved those constitutional questions and entered an injunction, the Supreme Court affirmed that judgment.

Real world impact

The ruling leaves in place the federal injunction preventing Mississippi from enforcing the 1908 statute against this railroad. That outcome lets the railroad continue interstate and intrastate operations in Mississippi without facing the threatened forfeitures in this case. It also confirms that federal courts can resolve similar constitutional challenges when a corporation’s out‑of‑state status is properly alleged.
