<i>¹This emergency action expired without being superseded by a permanent action. Upon expiration of an emergency action enacting a new Section, the Section is no longer effective. Therefore, on 7-15-02 (after the 7-14-02 expiration of the emergency action), Section 325:25-1-30.1 was no longer effective, and remained as such until added by permanent action on 5-15-13.</i>
