Question juridique clé
Whether service of the cantonal judgment on the defendant in Algeria was null because it was not made through diplomatic or consular channels.
Solution extraite
The defendant could not rely on the alleged defect in service because no prejudice resulted, the appeal period was respected, and the judgment created no enforcement effects in Algeria.
Motifs extraits
The service rules protect foreign sovereignty; as a private person the complainant lacked standing to invoke their breach absent concrete disadvantage. Invoking nullity in these circumstances was abusive.
