Question juridique clé
Whether the federal appeal met the motivation requirements for challenging the cost order
Solution extraite
The appeal did not engage with the decisive reasoning of the cantonal court and therefore failed to satisfy the statutory motivation requirements.
Motifs extraits
The appellants attacked only peripheral points and did not address the cantonal court’s core findings on the necessity of the expert opinion and on their duty to bear the resulting costs; the appeal was thus inadmissible in simplified procedure.
