§ 1172. Severability of provisions. The powers granted and the duties
imposed by this article and the applicability thereof to any persons,
tax districts or circumstances shall be construed to be independent and
severable and if any one or more sections, clauses, sentences or parts
of this article, or the applicability thereof to any persons, tax
districts or circumstances shall be adjudged unconstitutional or
invalid, such judgment shall not affect, impair or invalidate the
remaining provisions thereof or the applicability thereof to other
persons, tax districts or circumstances, but shall be confined in its
operation to the specific provisions so held unconstitutional and
invalid and to the persons, tax districts and circumstances affected
thereby.
