(A) If any section of this code now enacted or subsequently amended or its application to any person or circumstances is held invalid, the invalidity does not affect other sections that can be given effect without the invalid section or application.
(B) Except in the case of a section or amendment to this code containing a nonseverability provision, each division or part of every section is severable. If any portion or application of a section is held invalid, the invalidity does not affect the remainder of the section unless:
(1) The remainder is so essentially and inseparably connected with and so dependent upon the invalid provision or application that it cannot be presumed that the remainder would have been enacted without the invalid provision or application; or
(2) The remainder is incomplete and incapable of being executed in accordance with the legislative intent without the invalid provision or application.
(C) This section applies to every section of this code regardless of whether a section was enacted before or after the passage of this code.
(D) The repeal of a statute stating that the provisions of an act are severable as provided in division (B) above does not affect the operation of division (B) above with respect to that act.
