Question juridique clé
Whether the appeal was admissible against the cantonal remand decision under Art. 93 BGG
Solution extraite
The remand decision was an intermediate decision causing no irreparable harm and not saving significant time or costs; the appeal was therefore inadmissible.
Motifs extraits
The lower court merely confirmed liability in principle and sent the case back for further clarification of the amount. This only prolongs the proceedings and does not satisfy either Art. 93(1)(a) or (b) BGG.
