Horace Gray, Nutting v. Massachusetts — Opinion of the Court
“ Massachusetts Argued: November 20, 21, 1901. --- Decided: January 13, 1902 A state has the undoubted power to prohibit foreign insurance companies from making contracts of insurance, marine or other, within its limits, except upon such conditions as the state may prescribe, not interfering with interstate commerce. A contract of marine insurance is not an instrumentality of commerce, but a mere incident of commercial intercourse. ”
