Concurrent powers are powers in nations with a federal system of government that are shared by both the federal government and each constituent political unit (such as a state or province). These powers may be exercised simultaneously within the same territory, in relation to the same body of citizens, and regarding the same subject-matter. Concurrent powers are contrasted with reserved powers (not possessed by the federal government) and with exclusive federal powers (possession by the states is forbidden or requires federal permission). Federal law is supreme, and therefore it may preempt to a state or provincial law in case of conflict.
