Ala. Code § 37-14-39
If any part of Section 37-14-32, Section 37-14-33 or Section 37-14-36 of this article is declared invalid under the constitution or laws of this state, including invalidity as a result of impairing unconstitutionally the obligations of a municipal franchise, such declaration shall render invalid all parts which remain; provided, however, that any ruling that the provisions of this article impair unconstitutionally the obligations of any contract other than a municipal franchise shall not render invalid the application of the article in all instances not covered by such contract. Notwithstanding such invalidity, action taken by any party in conformity with the provisions of this article shall be considered lawful actions by such party; provided, however, any electric service rendered which would have been illegal or unlawful or violative of any contractual provision absent this article shall be terminated and the facilities shall be removed following any determination of the invalidity of this article. In all other respects, the provisions and applications of this article shall be deemed to be severable and a declaration of invalidity as to any other part or as to any application thereof to any person or circumstance shall not render invalid the parts or applications which remain.
