After having lived for generations under governments in which there was no effective division of powers, the people of the various colonies in setting up their own governments at the time of the Revolution very generally declared for such division, in more or less explicit terms. Even in the few cases where the division was not expressly made, it was implied in the constitution. The provision in the constitution of Massachusetts adopted in 1780 may be cited as an example of the strength of the conviction. "In the government of this Commonwealth the legislative department shall never exercise the executive and judicial powers or either of them; the executive shall never exercise the legislative and judicial powers or either of them; the judicial shall never exercise the legislative and executive powers or either of them." To this provision were appended, as the reason for it, the memorable words, "To the end that it may be a government of laws and not of men." From 1776 to the present century as new states were formed their people in most instances have adopted similar provisions. Perhaps the people of Maine when they separated from Massachusetts in 1820 adopted the most stringent provision by prohibiting not only the departments but all the persons in either department from exercising any of the powers properly belonging to either of the other departments. Of course some exceptions to the rule are necessary and these are usually named in the constitution itself. Again the dividing line between the powers cannot always be precisely defined and, further, each department in the performance of its own proper functions may sometimes be obliged to exercise a power strictly pertaining to another department. All that the maxim requires is that the three powers should be kept as distinct and separate as possible and have the government still go on. It is true we should not fear to question the wisdom of our fathers, but conclusions they have arrived at in matters of government after long study, observation, and actual experience should not be disregarded unless their error can be clearly demonstrated.
