Inspection laws, quarantine laws, health laws of every description, as well as laws for regulating the internal commerce of a State, and those which respect turnpike roads, ferries, &c., are component parts of this mass. No direct general power over these objects is granted to Congress, and, consequently, they remain subject to State legislation.” ~ Justice John Marshall (1755-1835) US Supreme Court Chief JusticeSource: Gibbons v. Ogden, 22 U.S. (9 Wheat.) 1 (1824)
