Louisiana Revised Statutes Tit. 39, § 1451. Publication of resolution or ordinance; peremption

A. Any resolution or ordinance authorizing the issuance of refunding bonds shall be published one time in the official journal of the issuer or, if the issuer does not have an official journal, one time in a newspaper of general circulation within the jurisdiction of the issuer; however, it shall not be necessary to publish any exhibits to such resolution or ordinance if the same are available for public inspection and such fact is stated in the publication.

B. For thirty days after the date of publication, any person in interest may contest the legality of the resolution or ordinance, any provision of the refunding bonds to be issued pursuant to it, the provisions therein made for the security and payment of the refunding bonds and the validity of all other provisions and proceedings relating to the authorization and issuance of such bonds.

C. After the said thirty days, no person may contest the regularity, formality, legality or effectiveness of the resolution or ordinance, any provisions of the refunding bonds to be issued pursuant to it, the provisions for the security and payment of the refunding bonds and the validity of all other provisions and proceedings relating to their authorization and issuance, for any cause whatever. Thereafter, it shall be conclusively presumed that the refunding bonds are legal and that every legal requirement for the issuance of the refunding bonds has been complied with. No court shall have authority to inquire into any of these matters after the said thirty days.
