In the United States, the District of Columbia offers an illustration of devolved government. The District is separate from any state, and has its own elected government. In many ways, on a day-to-day basis, it operates much like another state, with its own laws, court system, Department of Motor Vehicles, public university, and so on. However, the governments of the 50 states reserved a broad range of powers in the U.S. Constitution, and most of their laws cannot be voided by any act of U.S. federal government. The District of Columbia, by contrast, is constitutionally under the sole control of the United States Congress, which created the current District government by statute. Any law passed by the District legislature can be nullified by congressional action, and indeed the District government could be significantly altered or eliminated entirely by a simple majority vote in Congress.
