Kernrechtsfrage
Whether the civil appeal could challenge the cantonal court's application of German law under Art. 96 LTF.
Extrahierter Entscheid
Art. 96(a) LTF allows review only if the cantonal court applied a foreign law other than the one designated by Swiss PIL rules; it does not permit review of the correctness of applying the designated foreign law.
Extrahierte Begründung
The dispute concerned a monetary claim, so Art. 96(b) LTF on non-pecuniary cases was unavailable. Correct application of foreign law could therefore only be attacked via Art. 95(a) LTF alleging arbitrariness, which the appellant did not do.
