Louisiana Revised Statutes Tit. 13, § 4209. Decisions by successor judge

A. In all cases heard and taken under advisement of the district judge or judges of the city courts, if the judge before whom a case is tried dies, resigns, or is removed from office, or if his term expires before rendering his judgment in the case, his successor in office shall decide the case from the evidence in the record, if all of the testimony is in writing. If it is a case in which the testimony has not been reduced to writing, the succeeding judge shall decide the case from a statement of the facts, if one is found in the record, or if the parties to the suit agree upon a statement of facts. If the testimony is not in the record, and there is no statement of facts, the case shall be tried de novo.
