Which governmental powers are primarily defined by the Full Faith and Credit Clause?

The Full Faith and Credit Clause, found in Article IV, Section 1 of the U.S. Constitution, mandates that states must recognize and respect the public acts, records, and judicial proceedings of every other state. This clause primarily pertains to state powers because it establishes the obligation of states to honor the legal decisions and official documents (such as marriage licenses, court judgments, etc.) from other states.

This requirement ensures a level of consistency and unity among the states in the federal system, allowing for smoother interaction and legal proceedings across state lines. Each state's ability to depend on the recognition of its laws and legal decisions by other states underscores the significance of state authority in maintaining domestic legal coherence and respect for state sovereignty.

In contrast, the other options—federal powers, local powers, and concurrent powers—are not directly influenced by the Full Faith and Credit Clause. Federal powers pertain to the authority exercised by the national government, local powers are specific to municipal or local governments, and concurrent powers involve authorities shared by both state and federal governments. However, the Full Faith and Credit Clause specifically targets state interactions and obligations, thus reinforcing state powers as defined in the correct choice.
