One of the principal objections to the Articles of Confederation--that they lacked a practical amending power--applies, then, with no less force to the Constitution itself. In one respect the Constitution is even more rigid than were the Articles of Confederation, since the Congress of the Confederation was the court of last resort for passing on the constitutionality of its own legislation. This gave to Congress under the Confederation at least a limited power of virtually amending the Articles of Confederation by the ordinary process of law-making--a power possessed by the legislature in all countries where the system of checks and balances is not recognized. Under the Constitution, however, this power to amend the fundamental law can be exercised only to a very limited extent by Congress, since the interpretation of the Constitution by that body for the purposes of law-making is subject to revision at the hands of the Federal Judiciary. The Constitution, then, more effectually prevents changes desired by the majority than did the Articles of Confederation, since the former guards against the possibility of amendment under the guise of ordinary legislation while the latter did not. Another distinction must be borne in mind. The Articles of Confederation made amendment difficult in order to prevent the general government from encroaching on the rights of the several states. It was not so much a disposition to make change impossible, or even difficult, as, by keeping the general government within established bounds, to leave the several states free to regulate their own affairs and change their institutions from time to time to suit themselves. This view finds support in the character of the early state constitutions. These were shaped by the same revolutionary movement which produced the Declaration of Independence, and were largely influenced in their practical working by the "self-evident" truths proclaimed in the latter. One of the axioms of political science embodied in the Declaration of Independence was the right of the people to alter or abolish the existing form of government. This principle, however, was expressly recognized in but few of the earlier state constitutions, which, as a rule, contained no provision for future amendment. But such provision was not really necessary, inasmuch as the power of the legislature was limited only by its responsibility to the electorate. A mere majority of the qualified voters might demand and secure the enactment of laws which would virtually amend the constitution. From this time on, however, we see a strong tendency to specify in the constitution itself the manner in which it could be changed; and by the time that the framers of the Federal Constitution met in Philadelphia in 1787 a majority of the state constitutions contained provisions of this kind.
