Question juridique clé
Whether the public law appeal could challenge the first-instance judgment and incident orders directly
Solution extraite
The appeal was admissible only against the cantonal appellate judgment; challenges to the first-instance judgment and preparatory orders were inadmissible.
Motifs extraits
Because the cantonal appeal had full devolutive effect and the cantonal appellate court was not more limited than the Federal Court, the conditions for directly attacking the lower decisions were not met.
