Poppycock. If that was true the Endangered Species Act would have no teeth at all in Federal court.

OK, now I'll name you a treaty that so WILDLY exceeds Constitutionally enumerated powers as to be laughable: The Convention on Nature Protection and Wild Life Preservation in the Western Hemisphere commits all land in the United States and its entire economy to saving EVERY species, essentially claiming the power to halt natural selection in its tracks.
“Poppycock. If that was true the Endangered Species Act would have no teeth at all in Federal court.”
And what language in the Bill of rights forbids the Endangered Species Act, as bad as the legislation is?
