Question juridique clé
Whether the reform appeal was admissible despite incomplete challenges to independent grounds and to costs/conclusions.
Solution extraite
The appeal was inadmissible because it did not attack all independent grounds of the cantonal decision and sought relief that was not open in reform proceedings, including cantonal costs.
Motifs extraits
When a judgment rests on several independent reasons, the appellant must challenge each one. The defendants attacked only one motivation concerning default interest and did not properly contest the subsidiary ground. Their requests concerning cantonal costs were also outside the scope of federal civil law review.
