Section 1501. Constitutionality

  If any part, provision or section of this
  chapter, or the application of any such part, provision  or  section  in
  any  particular  respect,  shall  be  adjudged by any court of competent
  jurisdiction to be unconstitutional or ineffective in whole or in  part,
  such  judgment  shall  be  confined  in  its operation to the particular
  provision or section or application directly involved in the controversy
  in which such judgment shall have been rendered and  shall  not  affect,
  impair  or  invalidate  the  remainder of such provisions or sections or
  their application in  other  respects;  and  to  the  extent  that  such
  provisions  or  sections  are  not unconstitutional or ineffective, they
  shall remain in full force and effect.
