La. Stat. tit. 13 § 4449
In any case pending before the courts of appeal in which the judges thereof may desire the instructions or opinion of the Supreme Court on any question of law arising therein, the judges of the intermediate appellate court shall submit to the Supreme Court, a clear and concise statement in writing signed by them of the points or propositions of law concerning which the opinion of the court is desired and solicited. Should the Supreme Court deem an examination of the records necessary to a proper decision of the question of law so certified and submitted to it, the judges of the court of appeals, on receipt of a written request therefor, shall forward the original record to the clerk of the Supreme Court for the latter's consideration. Thereupon the Supreme Court may give its opinion on the points or propositions of law so submitted, which opinion, with the original record, shall be transmitted by the clerk of the Supreme Court to the court of appeals. The Supreme Court's opinion shall be binding on the judges of the court of appeal, and they shall proceed to determine and dispose of the cause in conformity with the principles stated therein.
