(a) Before a loan agreement may become effective, a record of the proceedings of the board and the political subdivision or water supply corporation authorizing the execution of the loan agreement, the loan agreement, the promissory note, and any contract providing revenue or security to pay the promissory note must be submitted to the attorney general for review and approval.
(b) If the attorney general finds that the loan agreement and the promissory note are valid and binding obligations of the political subdivision or water supply corporation, the attorney general shall approve the documents and deliver them to the comptroller, the board, and the subdivision or corporation, together with a copy of the attorney general's legal opinion stating that approval.
