Stanley Forman Reed,
Interstate Oil Pipe Line Company v…
“ So long as a tax on the privilege of doing interstate business or a tax on the doing of that business is prohibited, interstate commerce remains free from state exactions levied on that commerce. Yet that commerce must bear like intrastate commerce the cost of those facilities or protections apart from the interstate commerce itself which the state furnishes or allows within its borders. Such as been and is the freedom that the commerce clause grants to those engaged in commerce between the states. ”
