If any part of this Article is for any reason held unconstitutional, inoperative, or void, such holding of invalidity shall not affect the remaining portions of the Article; and it shall be construed to have been the legislative intent to pass this Article without such unconstitutional, invalid, or inoperative part therein; and the remainder of this Article, after the exclusion of such part or parts, shall be valid as if such parts were not contained therein.
