Supreme Court Rules Maryland State Income Tax Violates Dormant Commerce Clause: In a 5-4 decision, the United States Supreme Court ruled in Comptroller of Treasury of Maryland v. Wynne that Maryland’s state income tax system violates the dormant commerce clause because it fails the internal consistency test because, if every State adopted Maryland’s tax structure, interstate commerce would be taxed at a higher rate than intrastate commerce. The tax impermissibly operates as a tariff.
