Question juridique clé
Whether the Geneva court could modify costs that had already entered into force between Konsumenteninfo and PHP Distribution after only Éditions Plus had appealed.
Solution extraite
No. The prior judgment was final as to the dispute between Konsumenteninfo and PHP Distribution, including costs, and the cantonal court had no power to alter that part of the operative order.
Motifs extraits
In a multi-defendant case with independent claims, the judgment is materially severable. If only one defendant appeals, the non-appealed part enters into force, including the costs allocation, and cannot be reopened by the cantonal court on remand.
