Louisiana Revised Statutes Tit. 33, § 3319. Prescriptive period to question validity of proceedings

No contest or proceeding to question the validity, legality, ranking, or status of any resolutions or ordinances adopted or proceedings initiated under the provisions of this Subpart, including but not limited to the ranking or status of such resolutions or ordinances operating as a lien and privilege as provided in R.S. 33:3306, shall be begun in any court by any person for any cause whatsoever, after the expiration of thirty days from the date when the resolution, ordinance, or proceeding was published, and after such time the regularity of such resolution, ordinance, or proceeding shall be conclusively presumed. If the validity of any certificates issued under the provisions of this Subpart is not raised within thirty days from the date of publication of the resolution or ordinance issuing said certificates and fixing their terms, the authority to issue said certificates, the legality, ranking, and status thereof and of the local or special assessments necessary to pay the same shall be conclusively presumed and no court shall thereafter have authority to inquire into such matters. Moreover, the time period for recordation of a debt as a privilege and lien as set forth in Civil Code Art. 3274 shall not apply to the ranking and status of a lien and privilege as authorized by R.S. 33:3306.
