The U.S. Supreme Court found to be illegal a West Virginia state tax break that provided an exemption from state tax for retired state law enforcement employees but did not offer the same benefit to retired federal law enforcement employees.  The Court unanimously ruled in the case of Dawson v. Steager, Case No. 17-419 that the West Virginia court was in error finding that the law was acceptable since it applied only to a narrow class of retirees and did not intend to discriminate against federal marshals.
