Kernrechtsfrage
Whether the cantonal court arbitrarily found that the Luxembourg holding company was created on the respondent's sole mandate and not jointly with the appellant.
Extrahierter Entscheid
No. The evidence assessment was not manifestly untenable; the appellant mainly reargued the evidence.
Extrahierte Begründung
The court relied on witness testimony, formal interrogations, financing flows, and the timing of instructions. The written documents invoked by the appellant were either contested, later, or based on his own instructions, so the cantonal court could discount them without arbitrariness.
