A mechanism that guards against absolute power in any governing body by providing for separate governing bodies having equal power. Power is equitably distributed or balanced amongst the various branches of government (e.g., legislative, judicial, executive) and provisions are made for checking or restricting too much power in any one office. The system of cheques and balances is a major part of the American system of government provided by the Constitution to prevent any person or persons or sector of government from gaining too much power. The system emphasises the interdependence of various forms of government. It operates among the judicial, executive, and legislative branches of government as well as between state and national governments. Examples of how the systems works are: the ability of Congress to impeach a public official; the interpretation by the Supreme court of a legislative action; and the Presidential veto.
