The essential fact, everywhere to be observed in the development of constitutional government, is the rise to political power of classes which compete with the King and with each other for the control of the state. The monopoly of political power enjoyed by the King was broken down in England when the nobility compelled the signing of Magna Charta. This change in the English Constitution involved the placing of a check upon the King in the interest of the aristocracy. Later, with the development of the House of Commons as a separate institution, the power of the King was still further limited, this time in the interest of what we may call the commercial and industrial aristocracy. At this stage of its development the English government contained a system of checks and balances. The King still retained legislative power, but could not use it without the consent of both Lords and Commons. Each branch of the government possessed the means of defending itself, since it had what was in effect an absolute veto on legislation. This is a stage in political evolution through which governments naturally pass. It is a form of political organization intermediate between monarchy and democracy, and results from the effort to check and restrain, without destroying, the power of the King. When this system of checks was fully developed the King, Lords and Commons were three coordinate branches of the English government. As the concurrence of all three was necessary to enact laws, each of these could defeat legislation desired by the other two. The development of this system of checks limited the irresponsible power of the King only on its positive side. The negative power of absolute veto the King still retained. While he could not enact laws without the consent of the other two coordinate branches of the government, he still had the power to prevent legislation. The same was true of the Lords and Commons. As each branch of government had the power to block reform, the system was one which made legislation difficult. The system of checks and balances must not be confused with democracy; it is opposed to and can not be reconciled with the theory of popular government. While involving a denial of the right of the King or of any class to a free hand in political matters, it at the same time denies the right of the masses to direct the policy of the state This would be the case even if one branch of the government had the broadest possible basis. If the House of Commons had been a truly popular body in the eighteenth century, that fact would not of itself have made the English government as a whole popular in form. While it would have constituted a popular check on the King and the House of Lords, it would have been powerless to express the popular will in legislation.
