(B) Contesting Ordinance or Resolution; Time Limit. Every ordinance or resolution authorizing the issuance of bonds or other debt obligation by a political subdivision shall be published at least once in the official journal of the political subdivision or, if there is none, in a newspaper having general circulation therein. For thirty days after the date of publication, any person in interest may contest the legality of the ordinance or resolution and of any provision therein made for the security and payment of the bonds. After that time, no one shall have any cause of action to test the regularity, formality, legality, or effectiveness of the ordinance or resolution, and provisions thereof for any cause whatever. Thereafter, it shall be conclusively presumed that every legal requirement for the issuance of the bonds or other debt obligation, including all things pertaining to the election, if any, at which the bonds or other debt obligation were authorized, has been complied with. No court shall have authority to inquire into any of these matters after the thirty days.
