other states; state courts may not reopen cases which have been conclusively decided by the courts of another state. Later, Chief Justice John Marshall suggested that the judgment of one state court must be recognized by other states' courts as final. However, in McElmoyle v. Cohen, , the court heard a case where one party obtained a judgment in South Carolina and sought to enforce it in Georgia, which had a statute of limitations that barred actions on judgments after a certain amount of time had passed since the judgment was entered. The court upheld Georgia's refusal to enforce the South Carolina judgment. The court found that out-of-state judgments are subject to the procedural law of the states where they are enforced, notwithstanding any priority accorded in the states in which they are issued. Section 2: Rights of state citizens; rights of extradition Clause 1: Privileges and Immunities Clause One of Section 2 requires interstate protection of "privileges and immunities". The seeming ambiguity of the clause has given rise to a number of different interpretations. Some contend that the clause requires Congress to treat all citizens equally. Others suggest that citizens of states carry the rights accorded by their home states while traveling in other states. Neither of these theories has been endorsed by the Supreme Court, which has held that the clause means that a state may not discriminate against citizens of other states in favor of its own citizens. In Corfield v. Coryell, 6 F. Cas. 546 (C.C.E.D. Pa. 1823), the federal circuit court held that privileges and immunities in respect of which discrimination is barred include protection by the Government; the enjoyment of life and liberty ... the right of a citizen of one State to pass through, or to reside in any other State, for purposes of trade, agriculture, professional pursuits, or otherwise; to claim the benefits of the writ of habeas corpus; to institute and maintain actions of any kind in the courts of the State; to take, hold and dispose of property, either real or personal; and an exemption from higher taxes or impositions than are paid by the other citizens of the State. Most other benefits were held not to be protected privileges and immunities. In Corfield the circuit court sustained a New Jersey law giving state residents the exclusive right to gather clams and oysters. Clause 2: Extradition of fugitives Clause Two
