Questão jurídica principal
Whether the appeal could challenge the cantonal court's application of Liechtenstein law on piercing the corporate veil and foundation law.
Decisão extraída
The appeal failed on that point: attacks directed at the substantive application of Liechtenstein law were inadmissible under federal appeal review.
Fundamentação extraída
The federal appeal can examine whether Swiss law was wrongly applied instead of foreign law, but it does not review the cantonal court's substantive application of the foreign law itself.
