Concurrent powers are powers of a federal state 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.
[1] Concurrent powers are contrasted with reserved powers (not possessed by the federal government) and with exclusive federal powers (forbidden to be possessed by the states, or requiring federal permission).
[2] In the United States, examples of the concurrent powers shared by both the federal and the state governments include the powers to tax, to spend, and to create lower courts.
