Key legal question
Whether Swiss law governed the account relationship despite the foreign domicile of the claimant
Extracted holding
Swiss law applied because the bank rendered the characteristic performance in Switzerland and the contract had its closest connection to Swiss law under PILA.
Extracted reasoning
The court confirmed application of the mandate rules and held that, irrespective of any choice-of-law clause, Article 117 PILA led to Swiss law due to the bank's seat in Switzerland.
