Answer:
Article IV of the US Constitution addresses relations between the states in three ways:
Full Faith and Credit Clause: This clause requires each state to recognize the laws, court decisions, and public records of other states. For example, a marriage certificate issued in one state must be recognized as valid in another state.
Privileges and Immunities Clause: This clause prohibits states from discriminating against citizens of other states. It ensures that citizens have the same basic rights and protections, such as the right to travel, regardless of which state they are in.
Interstate Extradition: This clause requires that individuals who commit a crime in one state and flee to another state be returned to the original state to face charges. It ensures that criminals cannot evade justice by simply crossing state lines.
