La. Stat. tit. 38 § 2217
In all public building, construction or other contracts which do not provide the right to independent arbitration with both parties having equal authority in selection of the arbitrator or arbitrators, the right of each party to such contract to judicial review of and redress for any action, determination or interpretation made under or with respect to such contract shall not be denied. In any such judicial action, no prior nonjudicial decision, determination or interpretation shall have any binding or conclusive or presumptive effect, nor shall there be any limitation upon the evidence which may be introduced in such action except the limitations arising out of the application of the rules of evidence applicable in courts of this state. The provisions of this Section may not be waived.
