Constitution of the United States
Original frame
Article Four outlines the relations among the states and between each state and the federal government. In addition, it provides for such matters as admitting new states and border changes between the states. For instance, it requires states to give "full faith and credit" to the public acts, records, and court proceedings of the other states. Congress is permitted to regulate the manner in which proof of such acts may be admitted. The "privileges and immunities" clause prohibits state governments from discriminating against citizens of other states in favor of resident citizens. For instance, in criminal sentencing, a state may not increase a penalty on the grounds that the convicted person is a non-resident.
