History of the United States Constitution

Although the New Jersey Plan only survived three days as an alternate proposal, substantial elements of it were adopted. The articles were ``revised, corrected and enlarged'' for good government and preservation of the Union. The Senate is elected by the states, at first by the state legislatures. Congress passes acts for revenue collected directly in the states, and the rulings of state courts are reviewed by the Supreme Court. State apportionment for taxes failed, but the 'house' is apportioned by the population count of free inhabitants and three-fifths of others originally. States can be added to the Union. Presidents appoint federal judges. Treaties entered into by Congress are the supreme law of the land. All state judiciaries are bound to enforce treaties, state laws notwithstanding. The President can raise an army to enforce treaties in any state. States treat a violation of law in another state as though it happened there.
