Question juridique clé
Whether the insurer's appeal was admissible against the cantonal ruling on costs of the opposition proceedings.
Solution extraite
The appeal was inadmissible on that point because the remittal on legal costs was an incidental decision causing no irreparable prejudice.
Motifs extraits
The insurer still had discretion on the costs issue, so no irreparable harm was shown under Art. 93 LTF.
