Rule of Law and Separation of Powers: A Comparative Analysis of Dicey and Montesquieu

Abstract

The rule of law and the separation of powers are two fundamental principles of modern constitutionalism that have been influenced by the political thought of A.V. Dicey and Montesquieu. Dicey, a British jurist, emphasized the equality of all individuals before the law and the primacy of the law above arbitrary administrative authority. The legislative, executive, and judicial branches of government should be independent, according to French philosopher Montesquieu. The purpose of this essay is to examine the ways in which Dicey and Montesquieu influenced Western political systems, particularly those in the US, France, and the UK. It will also look at the shortcomings and difficulties of their theories in light of the development of human rights, judicial review, and the modern administrative state. The paper will argue that while Dicey and Montesquieu provided valuable insights into the nature and function of constitutional government, their ideas need to be adapted and updated to reflect the changing realities and demands of modern democracy.
