La. Public Health and Safety § 40:420
In any proceeding relating in any way to any contract of a regional or consolidated housing authority, the authority shall be conclusively deemed to have become established and authorized to transact business and exercise its powers upon proof of the adoption of a resolution declaring the need of such authority by the governing body of each of the parishes or municipalities originally within the authority. This resolution is sufficient if it declares that there is a need for the authority and finds in substantially the terms used in R.S. 40:415(A) that the conditions enumerated as Paragraphs (1) and (2) therein exist. Copies of these resolutions duly certified by the presiding officers or secretaries or the clerks of the respective governing bodies are admissible in evidence in any proceeding.
