Question juridique clé
Whether the public law appeal was admissible against both the cantonal judgment and the first-instance provisional order.
Solution extraite
The appeal was inadmissible insofar as it sought direct annulment of the first-instance provisional order, because only the final cantonal instance could be challenged.
Motifs extraits
A public law appeal lies only against the last cantonal decision unless the cantonal instance lacked full powers of review, which was not the case here.
