As Lord Acton said ‘Power tends to corrupt and absolute power corrupts absolutely’. The principle of the separation of powers assumes that certain functions should be carried out by different institutions and that no one institution should trespass into the territory of another. Its origin date back to Aristotle, the father of Political Science. Although he did not discuss the issue in great detail, he analyzed the functions of the three branches without suggesting their separation. The separation of powers however, acquired greater significance when John Locke, an 18th century philosopher argued that the executive and legislative powers should be separate for the sake of liberty. Montesquieu was a political philosopher of France and regarded as the chief architect of the principles of Separation of powers. He argued that ‘all would be lost if the same man or the same ruling body… were to exercise these three powers’. Montesquieu based his ideas of the British Constitution in the 18th Century, as he saw it. His ideas were, however, idealized and not entirely accurate, since he did not appear to understand the exact roles of the various participants in the British constitutional set up. Modern day Critics of the doctrine, such as Sir Ivor Jennings and Geoffrey Marshall, have doubted whether the three functions of the UK constitution could be allocated separately among the branches of government. Barendt, on the other hand, points out that the primary purpose of the doctrine as to avoid tyranny arising from the over-concentration of power. Adam Tompkins has an alternative view that the separation of powers is bipolar. The crown and parliament. Finally, Barber has argued that the purpose of the doctrine is efficiency of government. Today, the separation of powers is more often suggested as a way to foster a system of checks and balances
