By its name, Separation of Powers is a governance model and a constitutional principle which ensures that the membership, powers, and functions of the major institutions of a state or federation are not stipulated in one single entity, or in other words, the governance power are divided into different organs or branches. One of the governmental roles is to protect the citizens’ rights and liberties, however in history violation of such rights and liberties had been acknowledged. Thus, the concept of Separation of Powers step in to reduce such probability. In its strict sense, it is the true form of separation of powers, where there is a clear distinction between the organs, as what Montesquieu stated in his book ‘Esprit des Lois’ (The Spirit of Laws) published in 1748, the three organs of government (executive, legislature, and judiciary) should have discrete and defined area of power and that there should be a clear distinction of functions between them. The countries which adapt separation of powers strictly include the United States and India. In contrast, separation of powers in its liberal sense accept minor overlapping of powers, subjected to the system of check and balance. The concept of Separation of Powers is often confused with the Check and Balance system. The former ensures that the branches of executive, legislature and judiciary body are prominent in their respective area, while the latter further enhance such function by keeping each other in check. The concept of Separation of Powers is vital in ensuring rights and liberties of a person to be well protected. Without separation of powers, dictatorship and the arbitrary rule would prevail, allowing chaos in the history would repeat. The purpose of adapting the system of separation of powers is to reduce the risk of abuse of power by avoiding its concentration in a single person or institution.
