After the proceedings for the issuance of bonds are complete, an authority may submit to the attorney general the bonds to be issued and the record of the proceedings. The attorney general shall examine and pass on the validity of the bonds and the regularity of the proceedings in connection with the bonds. If the proceedings conform to this chapter and are otherwise regular in form and if the bonds, on delivery and receipt of payment, will be binding and legal obligations of the authority that are enforceable according to their terms, the attorney general shall certify in substance on the back of the bonds that the bonds are issued in accordance with the constitution and the laws of the state.
