Publication of a notice to the taxpayers and citizens of the state shall be made in the manner and at the times specified in Section 11-81-222(d), except that publication shall be made in a newspaper customarily published not less often than five days during each calendar week in the Cities of Birmingham, Mobile, Montgomery and Huntsville.

Prior to the initial issuance and sale by the authority of obligations provided for in this chapter (whether in the form of bonds, bond anticipation notes or notes), the validity of those obligations (along with the validity of the payments in lieu of taxes required by Section 11-50A-7) shall be determined in a validation proceeding as provided in this section. Following the initial issuance and sale of obligations of the authority the validity of which shall have been determined as provided in the preceding sentence, the validation of any bonds, bond anticipation notes or notes subsequently issued and sold by the authority shall not be required.
