Ala. Code § 40-1-40

It shall be the duty of the Comptroller to cause suit to be brought, in the name of the state, against any and all persons by law charged with the collection of state taxes, or with any duty in regard to the state revenue, and their sureties, for failure to collect such taxes or to perform such duty; and he may also in such cases, as in his judgment the interest of the state requires it, cause suit to be brought against defaulting taxpayers for the taxes claimed from them by the state; and, in cases in which a reasonable doubt may exist as to the construction or validity of the law under which taxes are claimed, he may authorize an agreed statement of the facts of the case to be made for the speedy adjudication of the matter in controversy.
