Question juridique clé
Whether the federal court could review the first-instance judgment together with the cantonal appellate judgment.
Solution extraite
The first-instance judgment could not be challenged together with the cantonal appellate judgment because the appellate court had full review powers, unlike the federal court under public-law appeal.
Motifs extraits
A combined annulment is only possible when the lower authority had a narrower review power than the Federal Court; that condition was not met.
