Louisiana Revised Statutes Tit. 13, § 5122. Law applicable; legislative intent

All suits, actions and proceedings of whatever nature affecting the validity of bonds of any governmental unit, or the interest thereon, or the sale thereof, or the election, if any, authorizing the issuance of said bonds shall be brought only in accordance with the provisions of this Title. These provisions shall supersede all other acts and statutes on the subject and be controlling in all such cases notwithstanding the provisions of any other law or charter to the contrary; provided, however, nothing herein contained shall affect, change, alter or modify in any way any peremptive or prescriptive period for the contesting of bonds of governmental units or elections authorizing their issuance, established pursuant to the constitution and statutes of this state which shall continue to govern the time within which actions covered thereby may be filed. It is hereby declared that it is the intention of the legislature in enacting this law to provide a uniform, expeditious and equitable procedure with due regard for the public fisc and rights of persons in interest for the judicial determination of the validity of bonds and related proceedings where material and substantial questions with regard thereto are involved or a judicial determination of issues relating to bonds is necessary to insure the marketability of bonds in investment channels. It is not the intention of the legislature to require or to encourage the validation of all bonds by the judiciary.
