Missouri Pacific Railroad v. United States

Background

A railroad company that operates land-grant lines in Missouri and other states sued the United States seeking extra pay. The 1850s land-grant laws require those roads to carry the mails under the Post Office’s direction at prices Congress sets. A 1916 law told the Interstate Commerce Commission (ICC) to fix fair mail-transport rates and said land-grant railroads get only eighty percent of the compensation awarded other railroads. The ICC set space-based rates and included distributing space in railway post-office cars as part of the service, which led to the company’s claim.

Reasoning

The main question was whether the eighty-percent rule excluded pay for the distributing space and related facilities used to sort mail on trains. The Court found that the 1916 law authorized the ICC to set rates for transportation “and the service connected therewith,” and that Congress intended the eighty-percent allowance to cover like transportation and the incidental services. The Court explained that distributing space is a natural incident of transporting the mails and that the Post Office’s direction over mail carriage can require such facilities. It held that Congress may decide the reduction for land grants and affirmed the lower court’s dismissal.

Real world impact

Railroads that accepted land grants will generally receive only eighty percent of ICC-set mail compensation, including pay for distributing space in mail cars. Federal agencies can require and specify necessary mail equipment and treat those services as covered by the eighty-percent allowance. The decision leaves Congress and the ICC, not courts, with primary authority over these payment rules.
