Section 10 - Powers prohibited of States
1. No State shall enter into any treaty, alliance, or confederation; grant letters of marque and reprisal; coin money; make anything but gold and silver coin a tender in payment of debts; pass any bill of attainder, or ex post facto law, or law impairing the obligation of contracts; or grant any title of nobility.
2. No State shall, without the consent of the Congress, lay any imposts or duties on imports or exports, except what may be absolutely necessary for executing its inspection laws; and the net produce of all duties and imposts, laid by any State on imports, or exports, shall be for the use of the Treasury of the Confederate States; and all such laws shall be subject to the revision and control of Congress.
3. No State shall, without the consent of Congress, lay any duty on tonnage, except on seagoing vessels, for the improvement of its rivers and harbors navigated by the said vessels; but such duties shall not conflict with any treaties of the Confederate States with foreign nations; and any surplus revenue thus derived shall, after making such improvement, be paid into the common treasury. Nor shall any State keep troops or ships of war in time of peace, enter into any agreement or compact with another State, or with a foreign power, or engage in war, unless actually invaded, or in such imminent danger as will not admit of delay. But when any river divides or flows through two or more States they may enter into compacts with each other to improve the navigation thereof.
