If a party has filed separate suits in a city court and a district court which has territorial jurisdiction over the city court relating to the same cause of action but placing a claim for property damage in one court and a claim for personal injury in the other court, the city court upon contradictory motion, or upon the court's own motion, after contradictory hearing may transfer the suit in its court to the district court if the transfer serves the convenience of the parties and the witnesses and is in the interest of justice.
