Devolution Devolution is the statutory delegation of powers from the central government of a sovereign state to govern at a subnational level, such as a regional or local level. It is a form of administrative decentralization. Devolved territories have the power to make legislation relevant to the area.
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.
