Corporations may be formed under general laws; which laws may, from time to time, be altered or repealed. The General Assembly shall have the power to alter, revoke or annul any charter of incorporation now existing and revocable at the adoption of this Constitution, or any that may hereafter be created, whenever, in their opinion, it may be injurious to the citizens of this State; in such manner, however, that no injustice shall be done to the corporators.
