Question juridique clé
Whether a nullity complaint is admissible when the written complaint does not expressly list the statutory nullity grounds.
Solution extraite
Yes. A sufficient, analogous reference to one of the nullity grounds listed by statute is enough; express verbal citation of the grounds is not required.
Motifs extraits
The court followed prior practice under the civil procedure code: if an analogous invocation of the relevant grounds sufficed there, it must a fortiori suffice in the simpler labor-court procedure modeled on it.
