Answer and Explanation:
Article IV of the constitution, which includes the Full Faith and Credit clause, ensures that whenever a case is tried by the courts that belong to any state, and judgment is passed, the same judgment will be honored by the courts that belong to other states. The aim of the clause is to create a single platform of unity for various types of courts, and prevent them from picking up unnecessary legal fights with each another: the courts in any one state won’t have to reopen cases that have been concluded by courts in other states.
