Question juridique clé
Whether the federal filing was brought by the correct remedy against an incidental cantonal decision.
Solution extraite
The decision was an incidental civil decision and should have been challenged by a civil appeal, not a public-law appeal.
Motifs extraits
The matter fell under Art. 74(1)(b) LTF and, as an incidental decision, under Art. 93 LTF; the wrong label did not prejudice the appellant if the filing met the formal requirements of the proper remedy.
