Kernrechtsfrage
Which law governs the arbitral agreement in an international relationship?
Extrahierter Entscheid
The arbitration agreement is treated as a procedural contract and is governed by the lex fori, here Solothurn law, with the general rules of the Code of Obligations applied analogously.
Extrahierte Begründung
The arbitration clause is separate from the main contract; the law governing the main contract does not necessarily govern the arbitration agreement.
