Your suggestion was not regulation of interstate commerce.
It was to supply a specific additional tax to one single pipeline not applied to all the other pipelines that already bring Canadian Crude into the US.
Why does TransCanada’s pipeline, but only one of theirs, get a special tax that does not apply to Enbridge’s or others? Why would such a tax not apply to trains and trucks?
Quit trying to use the Federal Government to pick winners and losers in private industry.
Interstate Commerce Act Law & Legal Definition-
The Interstate Commerce Act was passed by the U.S. Congress in 1887 and created the Interstate Commerce Commission. It was designed to address the concerns about the monopoly of the railroads in existence at the time. It was a law that established the right of Congress to regulate private corporations engaged in interstate commerce.
Interstate commerce refers to the purchase, sale or exchange of commodities, transportation of people, money or goods, and navigation of waters between different states. Interstate commerce is regulated by the federal government as authorized under Article I of the U.S. Constitution. The federal government can also regulate commerce within a state when it may impact interstate movement of goods and services and may strike down state actions which are barriers to such movement.
