In the opinion, however, which was given in the court below, it is denied that the trustees under the charter had any property, immunity, liberty, or privilege in this corporation, within the meaning of this prohibition in the Bill of Rights. It is said that it is a public corporation and public property; that the trustees have no greater interest in it than any other individuals; that it is not private property, which they can sell or transmit to their heirs, and that therefore they have no interest in it; that their office is a public trust, like that of the Governor or a judge, and that they have no more concern in the property of the college than the Governor in the property of the State, or than the judges in the fines which they impose on the culprits at their bar; that it is nothing to them whether their powers shall be extended or lessened, any more than it is to their honors whether their jurisdiction shall be enlarged or diminished. It is necessary, therefore, to inquire into the true nature and character of the corporation which was created by the charter of 1769. There are divers sorts of corporations; and it may be safely admitted that the legislature has more power over some than others.[9] Some corporations are for government and political arrangement; such, for example, as cities, counties, and towns in New England. These may be changed and modified as public convenience may require, due regard being always had to the rights of property. Of such corporations, all who live within the limits are of course obliged to be members, and to submit to the duties which the law imposes on them as such. Other civil corporations are for the advancement of trade and business, such as banks, insurance companies, and the like. These are created, not by general law, but usually by grant. Their constitution is special. It is such as the legislature sees fit to give, and the grantees to accept.
