72 Pa. Stat. § 1801
It is the intention of the General Assembly that if this act cannot take effect in its entirety, because of the judgment of any court of competent jurisdiction holding unconstitutional any part or parts thereof, the remaining provisions of the act shall be given full force and effect as completely as if the part or parts held unconstitutional had not been included herein.
It is the intention of the General Assembly that, if any court of competent jurisdiction shall hold unconstitutional any provisions of this act transferring to a department, board, commission, or officer, the powers and duties heretofore exercised and performed by another department, board, commission, or officer, the provisions transferring such powers and duties shall thereby become inoperative, and that, in such event, the department, board, commission, or officer, heretofore exercising such powers and performing such duties shall continue to exercise and perform them. The remaining provisions of this act shall, in any such case, be given full force and effect.
