If any clause, sentence, paragraph or part of this act, or the application thereof to any person or circumstances, shall for any reason be adjudged by a court of competent jurisdiction to be invalid, such judgment shall not affect, impair or invalidate the remainder of this act and the application of such provision to other persons or circumstances, but such decision shall be confined in its operation to the clause, sentence, paragraph, or part thereof, directly involved in the controversy in which such judgment shall have been rendered and to the person or circumstances involved. It is hereby declared to be the legislative intent that this act would have been adopted had such invalid provisions not been included herein.
