N.C. Gen. Stat. § 63-9: Partial invalidity.

If any part or parts of this Article shall be held to be unconstitutional, such unconstitutionality shall not affect the validity of the remaining parts of this Article. The General Assembly expressly declares that it would have passed the remaining parts of this Article, if it had known that such part or parts thereof would be declared unconstitutional. (1929, c. 87, s. 9.)
