Question juridique clé
Whether the appellants' request for CHF 30,000 in procedural compensation was a new conclusion before the Supreme Court
Solution extraite
No; it concerned costs already decided by the cantonal court and did not enlarge the dispute.
Motifs extraits
Costs are ancillary to the merits and the court rules on them ex officio, so the request was not a prohibited new claim under Art. 99(2) LTF.
