“Ours is a government of laws, not of men.” Justice Robert H. Jackson in Youngstown Sheet & Tube Co. v. Sawyer (1952) Laurence H. Tribe, of Harvard Law School, strongly believes our Constitution and the Rule of Law must prevail over Federal bureaucrats regulating power plant's CO2 emissions in every state. Tribe writes there is no legislative authority granting the EPA the power to regulate. In fact the statutes clearly denies the EPA from regulating power plants.
