W. Va. Code § 18A-1-3: Constitutionality and severability.

If any provisions of this chapter or the application thereof to any person or circumstances shall be held to be unconstitutional and invalid, such unconstitutionality and invalidity shall not affect any one of the provisions or applications of the chapter which can be given effect without the invalid provisions or applications; and to this end the provisions of this chapter are separable. The Legislature hereby declares that it would have passed the remaining parts of this chapter if it had known that such other part or parts thereof would be declared unconstitutional and invalid.
