Tom C. Clark,
Railway Express Agency v. Virginia…
“ The General Assembly has made crystal-clear that the tax is now a franchise tax laid on the intangible property of appellant, and is levied 'in lieu of taxes upon all of its other intangible property and * * * rolling stock.' The measure of the tax is on gross receipts, fairly apportioned, and, as to appellant, is laid only on those 'derived from the transportation within this State of express transported through, into, or out of this State.'Appellant concedes that the Commerce Clause does not prohibit the States from levying a tax on property owned by a concern doing an interstate business. ”
