(10) To exercise discretion to defend the constitutionality and validity of all private acts and general laws of local application enacted by the general assembly and of administrative rules or regulations of this state.

(15) To attend to any other duty which may devolve upon, or be imposed upon, the attorney general and reporter by law.

(c) Notwithstanding § 8-6-106 to the contrary, in all cases in which the attorney general and reporter has certified to the speaker of each house of the general assembly the decision not to defend the constitutionality and validity of any law pursuant to subsection (b), the speakers, acting jointly, may employ legal counsel to defend the constitutionality of such law. Such counsel shall be paid such compensation for their services as the speakers may deem just; the same to be paid out of any money in the state treasury not otherwise appropriated, upon the certification of the speakers to the commissioner of finance and administration.
