Explanation:

The doctrine of the separation of powers is a state theory according to which the executive, legislative and judicial powers must belong to different bodies, controlling each other and serving as a limit for the exercise of the functions of each body.

The doctrine of the separation of powers is presented in Montesquieu's main work, The Spirit of Laws. Nowadays, it is a fundamental part of the governance of Western democracies. Thus, for example, the Constitution of the United States grants the President the exercise of the executive power, the Congress that of the legislative power, and the Supreme Court that of the judicial power. In turn, all these bodies control, limit and supervise each other through the checks and balances system, which establishes certain authorization or approval requirements for some tasks of each body.
