No provision of any law of the United States of America providing for or relating to the ad valorem taxation by a state of aircraft or flying equipment of an airline company shall be effective for the purposes of subdivision 1 until the attorney general of Minnesota shall have certified to the commissioner that in the attorney general's opinion such federal act is a valid exercise of federal authority under the Constitution of the United States.
The provisions of this section shall not affect the validity of any tax imposed under sections 270.071 to 270.079 prior to the effective date of such federal law.
