All authority heretofore conferred for any of the purposes aforesaid by the Legislature or by the charter of any corporation, is hereby repealed. Nothing in this section contained shall affect the right of any such corporation, municipality, or county to make such subscription where the same has been authorized under laws existing at the time of the adoption of this Constitution, and by a vote of the people thereof, had prior to its adoption, and where the terms of submission and subscription have been or shall be complied with, or to prevent the issue of renewal bonds, or the use of such other means as are or may be prescribed by law for the payment or liquidation of such subscription, or of any existing indebtedness.
