Kernrechtsfrage
Whether the forum clause 'Gerichtsstand ist Oberwil' in the AGB validly waived the defendants' home forum.
Extrahierter Entscheid
Yes. The clause was clear, the AGB were handed over with the offer, and the appellants' education and circumstances meant they had to understand the clause.
Extrahierte Begründung
A forum clause in AGB is valid if, under the reliance principle, the other party could in good faith assume assent; for a clear clause, even an average educated contract partner suffices. The appellants were over-average educated and therefore could not rely on ignorance.
