1. Charles Montesquieu(De l'esprit des lois, 1748, Chapter XI, 3–6) famously said that where the legislative and executive powers were united in the same person or body there could be no liberty. Again, there was no liberty if judicial power was not separated from the legislative and executive. There would be an end of everything if the same person or body were to exercise all three powers.
