If a question of nationality is raised by a party before a court that considers that there is a preliminary question, the court shall refer that party to appeal to the competent judicial court within a period of one month or, within the same period, to submit a request to the public prosecutor. Where the person whose nationality is in dispute relies on a certificate of French nationality, or where the question of nationality has been raised ex officio, the court hearing the case on the merits shall set the Public Prosecutor the same one-month time limit to refer the matter to the competent judicial court.
If the one-month time limit is not observed, the proceedings shall continue. Otherwise, the court hearing the case on the merits shall stay the proceedings until the nationality issue has been decided.
