One great step toward such a form of government was made in the establishment of our federal and state governments by giving effect to the theory of the tripartite nature of governmental powers, entrusting each of the three to a different person or group of persons, or, in other words, to a different department, each restraining the other departments from exceeding their defined powers, so that the government, however democratic, shall not run wild. At this day, however, even this feature of our form of government is assailed as hampering the people and their government and greatly delaying desired reforms. It may be admitted that a government with its powers thus separated in different departments is not able to act as quickly as desired by zealous persons confident of the excellence of their schemes and impatient for their realization, but, on the other hand, it is less liable to act too hastily, less liable to act arbitrarily, or to disregard individual rights and interests. The idea of a division of governmental powers is not of recent origin. Aristotle argued that the judges should have no other political power, should not themselves enforce their decisions. In Rome under the Republic there was divided between the pretor and the judex the power to decide controversies. The pretor had other duties, but the judex was confined to the single duty to hear and determine. The framers of our Federal Constitution and of our early state constitutions did not act hastily nor unadvisedly. As heretofore stated, the long controversy with Great Britain over the relations between that country and her Colonies, the arbitrary acts of the British King and Parliament, caused in the Colonies a profound study of the nature of government: what should be its purposes and how best to effect its purposes and avoid its abuses. The principal men among them in each Colony were familiar with the history of governments and with the theories of government advanced by European lawyers and political philosophers. They were acquainted with the arguments of Montesquieu and others that a separation of the powers of government and the vesting of each, the executive, legislative, and judicial, in different hands was essential to liberty. They did not merely theorize, however. They had themselves lived and labored under governments not thus divided in functions or only partially so. Colonial governors had assumed legislative functions in the promulgation of ordinances, and also judicial functions as judges of probate and in other ways. The colonial legislatures did not hesitate to dictate to the courts in particular cases and often acted as a court of appeal. In Massachusetts Bay the legislature came to be known as the General Court and exercised judicial power freely, sometimes calling in the judges to sit with them. The same individual could at one and the same time fill an executive and a legislative or judicial office.
