Canton Railroad v. Rogan

Background

Canton Railroad Company, a Maryland short‑line railroad that operates a marine terminal in the Port of Baltimore, challenged a Maryland franchise tax measured by gross receipts. Canton said a large part of its receipts came from handling goods destined for export or arriving as imports and therefore should be exempt under the Constitution’s rule against taxing imports and exports. The State Tax Commission, and then Maryland courts, rejected Canton’s claim and assessed a tax of $39,092.34 on higher reported gross receipts.

Reasoning

The Court addressed whether the Import‑Export Clause bars taxing the railroad’s gross receipts from port services. The majority said the tax is on Canton’s in‑state activities and not a tax on the goods themselves or their exportation. The opinion explained that the constitutional protection is narrower when a State taxes activities rather than the articles, and that activities more remote than the actual movement to or from shipboard are not part of export or import. The Court also noted that a nondiscriminatory gross‑receipts tax fairly apportioned to business within the State is permissible and that apportionment by in‑state mileage is an approved method.

Real world impact

The ruling allows Maryland to collect the assessed tax and generally permits similar taxes on in‑state handling and transport services tied to ports. Short‑line railroads, port operators, shippers, and state tax authorities will be directly affected because handling and transportation receipts can be taxed when properly apportioned. The decision affirms apportionment rules as a way to limit overreach but may raise costs for exporters when handling and carriage are taxed.

Dissents or concurrances

Two Justices (Jackson and Frankfurter) reserved judgment and warned that recognizing export status only at the water’s edge could undermine the Constitution’s purpose to protect inland producers and equal access to ports; they cautioned about unintended burdens.
