Question juridique clé
Whether the appeal was admissible despite containing only a request to annul the cantonal judgment and no merits conclusions.
Solution extraite
The appeal was inadmissible because the appellants did not seek a substantive ruling and did not show that remand would be the only possible relief.
Motifs extraits
Under Art. 42(1) and Art. 107(2) LTF, a party must ordinarily state conclusions on the merits; a mere request to annul is insufficient unless the court could not decide the merits itself.
