* The Separation of Powers between the legislature, the executive, and the judiciary constitute an important safeguard of liberty in a liberal democracy. * The doctrine of Separation of powers entails the division of the legislative, executive, and judicial functions of government among different organs. This separation minimizes the possibility of arbitrary excesses by the government since all three organs act as checks and balances on the powers of each other. Therefore, none of the three organs can usurp the essential functions of other organs. * This demarcation prevents the concentration of excessive power by any branch of the Government. It thus helps to safeguard the liberty and rights of the people in a democracy.
