Questão jurídica principal
Which law governs the arbitral agreement in an international relationship?
Decisão extraída
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.
Fundamentação extraída
The arbitration clause is separate from the main contract; the law governing the main contract does not necessarily govern the arbitration agreement.
