La. Public Health and Safety § 40:545
Except with respect to enforcing any right to indemnification under R.S. 40:516 or any right of an obligee under R.S. 40:475 and 476, and notwithstanding any other provision of law to the contrary, this Chapter shall not confer upon any person or organization a right of action in any court to enforce this Chapter. Except as otherwise stated in this Section, any and all rights to enforce this Chapter are vested exclusively in housing authorities and the municipalities and parishes of this state that establish housing authorities, and without limiting the foregoing, no person or entity not expressly named as a party to a contract entered into by a housing authority shall have any right of action, by virtue of the status of such person or entity as a third party beneficiary of such contract, or otherwise based upon such contract. Any claim or action in violation of this Section shall be absolutely null and void.
