U.S. ConstitutionArticle 1
Section 8. The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and provide for the common defense and general welfare of the United States; but all duties, imposts and excises shall be uniform throughout the United States.
Them thieving Founders!!!
Yes, actually. Just because someone writes a document that claims that a government has the right to levy a tax, does not make it so. To be valid, a contract requires the consent of all parties thereto.
