Where the court has declared itself to have jurisdiction and has ruled on the merits of the dispute in the same judgment given at first instance, that judgment may be appealed against in its entirety.
Where the court reverses on the ground of jurisdiction, it shall nevertheless rule on the merits of the dispute if the court is a court of appeal in relation to the court which it considers to have jurisdiction.
If it is not a court of appeal, the court, in reversing the contested decision on the ground of jurisdiction, remits the case to the court which is a court of appeal in relation to the court which would have had jurisdiction at first instance. This decision is binding on the parties and on the referring court.
