Question juridique clé
Whether the appeal could only seek annulment because the Federal Supreme Court could not decide the merits itself
Solution extraite
If the appellate judgment were incorrect, the Federal Supreme Court could not issue a final merits judgment, so only annulment of the cantonal decision was sought and admissible.
Motifs extraits
The challenged judgment was final; given the procedural posture, the Court could not itself render a final decision on the payment claim.
