Kernrechtsfrage
Who bore the burden of proving whether the bank delivered the shares from its own stock or bought them on the exchange?
Extrahierter Entscheid
By issuing a securities statement calling itself the self-contracting counterparty without naming another seller, the bank triggered the presumption of self-dealing; it had to rebut that presumption by proving an exchange purchase.
Extrahierte Begründung
Art. 437 OR, read with Art. 436(1) OR, does not distinguish between true and false self-entry for burden-of-proof purposes. The lower court wrongly placed the burden on the client, contrary to Art. 8 ZGB.
