Our Constitution’s Fourth Article is devoted to the relations between the states and the Union. Section 2 of that Article sets forth three Clauses, each of which concerns the movement of persons throughout the Union. The first of these, the Privileges and Immunities Clause, stipulates that the citizens of each state shall enjoy the “privileges and immunities of citizens” in the other states. Conversely, where the interstate traveller is a fugitive from criminal justice, the second provision he Extradition Clause requires the person’s forcible rendition to the state where the alleged crime occurred. Finally, the Fugitive Slave Clause (now obsolete) extended this rule of coercive rendition to interstate fugitives from slavery that is, fugitives from injustice.
