Missouri, Kansas & Texas Railway Co. v. United States

Background

A railroad company sued the Post Office for $9,429.92, claiming it was owed more pay for carrying mails from July 1, 1912, to July 1, 1914. The company had accepted a routine readjustment form in 1910 that said it would be "subject to all the postal laws and regulations." The company ran a fast mail train linking Kansas and Texas, then discontinued that train in early 1912. The Post Office said the change affected how much mail the railroad carried and ordered limited weighings and a later reduction in the railroad’s route pay.

Reasoning

The central question was whether the railroad’s earlier readjustment locked in fixed pay or whether the Postmaster General could change pay when mail service actually changed. The Court said the arrangement did not prevent later laws or adjustments. It relied on the company’s written acceptance that it would follow postal laws and on the 1912 statute allowing the Post Office to weigh diverted mails for a limited period and readjust pay if diversions were substantial. The Court accepted the Department’s interpretation of the statute’s ten percent test and held that the Department properly reduced the railroad’s compensation because the service change justified readjustment. Judgment was affirmed for the Government.

Real world impact

The decision confirms that the Post Office can correct pay when actual mail service changes, using short weighings instead of a full 90-day reweighing. Railroads cannot rely on a prior pay adjustment to guarantee unchanged payment if they stop important mail service, and affected pay can be reduced for past service changes.
