[quote=scaredyclassic]Wait, why is the epa “unconstitutional”?[/quote]
It has the potential to create and enforce laws extra-judicially and outside of the constitutionally stated process (laws are supposed to be written/enacted by Congress, signed by Pres, reviewed by Judicial). There is a somewhat accepted sidestep that Congress enacted the EPA, so it is now allowed, though still is a question whether the EPA can create laws in and of itself outside of Congress.
