Question juridique clé
Whether the federal appeal met the reasoning requirements of Art. 42 paras. 1-2 LTF.
Solution extraite
No. The appeal did not explain in a legally sufficient way why the cantonal judgment violated federal law.
Motifs extraits
The submission merely complained that the cantonal court ignored a date and a witness. It did not address the decisive legal reasoning, including the cited case law on default interest being owed regardless of fault.
