Article 81 of Code of Civil Procedure

A plea that the action is inadmissible may be raised at any stage of the action. If the court of first instance considers that the plea of inadmissibility of the action for lack of standing of the defendant is well founded, it shall adjourn the action for service on the person having standing. If the action is brought against a governmental entity or a public legal person, the effect of the correction shall extend back to the day the action was filed, even if the correction is made after the prescribed time limit for filing it.
