United States v. Missouri Pacific Railroad

Railroad route ruling limits federal regulator’s power, blocking an order that would have forced a large railroad to lose long-haul freight and protecting existing long-haul routes for carriers.

Holding

The Court affirmed that the Interstate Commerce Commission lacked authority under the statute to force carriers into the proposed through route over the Subiaco because it would exclude substantially the larger railroad’s full line between the route termini.

Real-world impact

  • Prevents regulator from forcing carriers into short through routes that cut long hauls.
  • Protects long-haul revenue for railroads by preserving existing full-line hauls.
  • Leaves change to law to Congress if broader routing power is desired.

Summary

Background

A small Arkansas railroad (the Subiaco) asked the federal railroad regulator to establish new westbound through routes over its 40-mile line to bring in more freight and revenue. A larger regional railroad (Missouri Pacific) objected because the new route would sharply shorten its haul on many shipments. The Interstate Commerce Commission ordered carriers to create the through routes. Missouri Pacific sued, and a three-judge district court set the order aside.

Reasoning

The core question was whether the law allows the regulator to force a carrier to accept a through route that does not include substantially the entire length of its line between the route’s endpoints. The Court looked at the statute’s paragraph that protects carriers’ long hauls and found the Commission’s order conflicted with that clear language. No statutory exception applied and the existing longer routes were not shown to be unreasonably long, so the Commission lacked power to compel the shorter route.

Real world impact

The Court affirmed the district court’s decision, so the ordered through routes over the Subiaco cannot be imposed under the statute as written. The ruling preserves long-haul revenue for carriers in situations like this and limits the regulator’s ability to reassign traffic onto short connecting lines. If broader authority is wanted, Congress must change the law.

Dissents or concurrances

The Commission’s internal decision included one dissent and two members did not participate, a fact noted by the Court but not decisive to its legal conclusion.
