Not to be confused with reserve power.

In comparative federalism and comparative constitutionalism reserved powers or residual powers are those powers which are not "enumerated" (written down, assigned). In various federal and decentralized political systems, certain areas are assigned to either the central (or federal) government or the regional (or state or provincial) government; however it is not possible to list all possible subject that might be legislated on for all time. Therefore, the framers of major constitutional documents tend to assign all other subjects that may arise after the document is enacted to one of the two orders of government. This is considered a major power in its own right.

In Canada, for example, the reserved powers lie with the federal government; in the United States, the reserved powers lie with the constituent states. [1]

Application around the world[edit]

In Australia, despite the centralized nature of the constitution, the High Court adopted the "reserved powers doctrine" which was used until 1920 to interpret the Constitution of Australia such that it should be read to preserve as much autonomy for the states as possible. The doctrine became obsolete with the Engineers' Case however the term "residual powers" continues to refer to the powers not explicitly mentioned in the Australian Constitution and as such, powers reserved to the states as being outside Federal jurisdiction.

In Bermuda, "reserved powers" are the powers that the British Governor of Bermuda has over External Affairs, Internal Security and the Police, see Politics of Bermuda.

In the United Kingdom "reserved matters", refers to those subjects dealt with solely by the United Kingdom Parliament, and not devolved to the Scottish Parliament, National Assembly for Wales or the Northern Ireland Assembly.

In the United States, the "reserved powers" are those powers which under the Tenth Amendment to the United States Constitution are reserved to the states or the people.
