CCP 2163     

Art. 2163.  Peremptory exception filed in appellate court; remand if prescription pleaded

The appellate court may consider the peremptory exception filed for the first time in that court, if pleaded prior to a submission of the case for a decision, and if proof of the ground of the exception appears of record.

If the ground for the peremptory exception pleaded in the appellate court is prescription, the plaintiff may demand that the case be remanded to the trial court for trial of the exception.
