The president, one of the old trustees, had a right to his office, salary, and emoluments, subject to the twelve trustees alone. His title to these is now changed, and he is made accountable to new masters. So also all the professors and tutors. If the legislature can at pleasure make these alterations and changes in the rights and privileges of the plaintiffs, it may, with equal propriety, abolish these rights and privileges altogether. The same power which can do any part of this work can accomplish the whole. And, indeed, the argument on which these acts have been hitherto defended goes altogether on the ground, that this is such a corporation as the legislature may abolish at pleasure; and that its members have _no rights, liberties, franchises, property, or privileges_, which the legislature may not revoke, annul, alienate, or transfer to others, whenever it sees fit. It will be contended by the plaintiffs, that these acts are not valid and binding on them without their assent,-- 1. Because they are against common right, and the Constitution of New Hampshire. 2. Because they are repugnant to the Constitution of the United States. I am aware of the limits which bound the jurisdiction of the court in this case, and that on this record nothing can be decided but the single question, whether these acts are repugnant to the Constitution of the United States. Yet it may assist in forming an opinion of their true nature and character to compare them with those fundamental principles introduced into the State governments for the purpose of limiting the exercise of the legislative power, and which the Constitution of New Hampshire expresses with great fulness and accuracy. It is not too much to assert, that the legislature of New Hampshire would not have been competent to pass the acts in question, and to make them binding on the plaintiffs without their assent, even if there had been, in the Constitution of New Hampshire, or of the United States, no special restriction on their power, because these acts are not the exercise of a power properly legislative. Their effect and object are to take away, from one, rights, property, and franchises, and to grant them to another. This is not the exercise of a legislative power. To justify the taking away of vested rights there must be a forfeiture, to adjudge upon and declare which is the proper province of the judiciary. Attainder and confiscation are acts of sovereign power, not acts of legislation. The British Parliament, among other unlimited powers, claims that of altering and vacating charters; not as an act of ordinary legislation, but of uncontrolled authority. It is theoretically omnipotent. Yet, in modern times, it has very rarely attempted the exercise of this power.
