Cummings v. Chicago

Background

A group of private landowners wanted to build a dock in the Calumet River and relied on federal laws and a permit from the Secretary of War to justify construction. The local authorities (including city rules requiring approval from Chicago’s Department of Public Works) opposed the work. The plaintiffs sued in federal court, claiming the United States had effectively taken control of the river and that federal approval alone should allow the dock to be built.

Reasoning

The key question was whether Congress intended its river-and-harbor laws to remove a State’s power to control structures in navigable waters located entirely within that State. The Court reviewed earlier decisions and the text of the River and Harbor Acts, and found no clear, explicit language showing Congress meant to override state authority for all purposes. The Court held that the federal statute and the Secretary of War’s permit do not by themselves displace state control. The Circuit Court had proper authority to hear the case, and the Supreme Court affirmed the lower court’s judgment.

Real world impact

After this ruling, people or companies who want to build docks, bridges, or similar structures in navigable waters completely inside a State must secure both federal approval (when required) and the State’s or local government’s consent. The decision confirms that States keep primary control over their internal waterways unless Congress clearly says otherwise, so local permitting requirements remain important.
