Kernrechtsfrage
Whether the buyer's objection that German company law should apply required referral or reversal
Extrahierter Entscheid
The dispute was governed by the expressly chosen Swiss law in the second contract; the German-law argument based on the first contract was irrelevant.
Extrahierte Begründung
The claim concerned performance of the independent second share purchase agreement of 19/20 April 2007, which contained an express choice of Swiss substantive law. Any alleged German partnership structure under the first contract could not displace that choice.
