N.H. Rev. Stat. § 38-A:21
The provisions of this chapter are severable, and if any of its provisions shall be held unconstitutional by any court of competent jurisdiction, the decision of such court shall not affect or impair any of the remaining provisions; and notwithstanding any other evidence of legislative intent, it is hereby declared to be the controlling legislative intent that if any provisions of this chapter, or the application thereof to any person or circumstances is held invalid, the remainder of the chapter and the application of such provision to persons or circumstances other than those as to which it is held invalid, shall not be affected thereby. Insofar as the provisions of this chapter are inconsistent with the provisions of any other law, the provisions of this chapter shall be controlling.
