Section 156. Separability

If any clause, sentence, paragraph, or part of
  this article 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 judgments shall not affect,  impair,  or  invalidate
  the  remainder  of  this  article,  and the application thereof to other
  person or circumstances, but 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 article would have been  adopted  had  such
  invalid provisions not been included.
