Limits pipeline owners’ ability to refuse carriage except under carrier duties.
Leaves a purely private owner-only refinery line exempt from the statute.

Summary

Background

The Interstate Commerce Commission ordered several pipeline owners to file their oil transportation rates after Congress amended the law in 1906 to cover pipe-line transport. A group of pipeline companies, many tied to a large oil company that controlled much pipeline access, sued and won an injunction in the Commerce Court. The injunction rested on a claim that the statute could not constitutionally apply to pipelines already operating across state lines.

Reasoning

The Supreme Court asked whether the 1906 amendment was meant to cover integrated pipeline systems that in practice carried interstate oil. The majority held that Congress intended to treat pipelines that function like common carriers as subject to federal regulation, focusing on substance over technical form. The Court reversed the lower court for the large companies that purchased or handled oil from many producers and effectively controlled transport. By contrast, the Court left in place the lower-court decision for one company that used a pipeline only to move its own oil to its own refinery across a state line.

Real world impact

The decision makes most of the named pipeline owners subject to federal oversight and to file rates with the Commission, limiting their ability to refuse carriage except on carrier terms. One purely private line carrying only its owner’s oil remains outside the statute under the Court’s view, though concurring and dissenting opinions raised different concerns about property rights and government power.

Dissents or concurrances

The Chief Justice agreed with the outcome but argued the excluded private line would be covered by the statute and only the Fifth Amendment’s protection against uncompensated taking justified exemption. Justice McKenna dissented, warning the ruling impaired property rights and due process.
