St. Louis, Iron Mountain & Southern Railway Co. v. United States

Background

A Missouri railroad company that ran tracks from Tower Grove to Texarkana sued the United States to recover freight charges for returning empty mail bags. Congress had given land to help build part of the railroad in 1853 and 1866 on the condition that government property and troops be carried without toll. In 1908 the Post Office ordered empty mail bags withdrawn from the mails before mail weighing and sent them by freight instead; the railroad billed $14,043.17, and the Post Office deducted $8,251.45, saying the bags were carried free under the old land-grant laws.

Reasoning

The Court addressed two questions: whether Congress could lawfully exclude empty bags from mail-weight calculations, and whether empty bags were “property” of the United States for land-grant purposes. The Court held Congress validly classified empty bags separately and so could exclude them from mail weighing. It also concluded the empty bags were United States property, and when the Government required their carriage the earlier land-grant statutes controlling free transport applied. The Court affirmed the Court of Claims and denied the railroad’s recovery.

Real world impact

The ruling means railroads that benefited from land grants may not charge the United States for transporting empty postal containers when the Government requires their carriage. The Post Office may exclude empty bags from mail-weight calculations, which can reduce payments to carriers. This decision affirms existing statutory obligations tied to historical land grants.

Dissents or concurrances

Justice McReynolds dissented, arguing empty sacks remain part of the mail and Congress did not intend to convert them into property for free transport, favoring freight charges instead.
