who proponded the concept of rule of law in britain
A. V. Dicey Albert Venn Dicey, KC, FBA (4 February 1835 â€“ 7 April 1922), usually cited as A. V. Dicey, was a British jurist and constitutional theorist. He is most widely known as the author of Introduction to the Study of the Law of the Constitution (1885). The principles it expounds are considered part of the uncodified British constitution. He became Vinerian Professor of English Law at Oxford and a leading constitutional scholar of his day. Dicey popularised the phrase "rule of law",[1] although its use goes back to the 17th century.
Separation of powers The term tripartite system is commonly ascribed to French Enlightenment political philosopher Baron de Montesquieu, although he did not use such a term. In reality he referred to "distribution" of powers. In The Spirit of the Laws (1748), Montesquieu described the various forms of distribution of political power among a legislature, an executive, and a judiciary. Montesquieu's approach was to present and defend a form of government which was not excessively centralized in all its powers to a single monarch or similar ruler, form of government known then as "aristocracy". He based this model on the Constitution of the Roman Republic and the British constitutional system. Montesquieu took the view that the Roman Republic had powers separated so that no one could usurp complete power.[8][9][10] In the British constitutional system, Montesquieu discerned a separation of powers among the monarch, Parliament, and the courts of law.
