|1.||the rights and powers generally conceded to the states, or all those powers claimed for the states under some interpretations of the Constitution|
|2.||a doctrine advocating the severe curtailment of Federal powers by such an interpretation of the Constitution|
Rights guaranteed to the states under the principle of federalism. Under the Constitution, states have considerable autonomy to pass, enforce, and interpret their own laws and to pursue their own public policy programs. Proponents of states' rights argue that the states should be governed with a minimum of interference from the federal government.
Note: The relationship between federal and state responsibilities has often been controversial. Until the middle of the twentieth century, for example, the Supreme Court left the interpretation of many civil rights guarantees to the states, resulting in hostile and widespread discrimination against minorities.
