Question juridique clé
Whether the state courts lacked jurisdiction because the lease contained an arbitration clause.
Solution extraite
The arbitration clause did not bar the state courts; by seizing the conciliation office without raising the clause, the tenant waived reliance on the clause by conclusive conduct.
Motifs extraits
For commercial leases, parties may exclude conciliation and state jurisdiction in favor of arbitration under Art. 274c CO; the clause was interpreted under Art. 18 CO and, since it did not mention conciliation, using the conciliation office without reservation signaled waiver of the arbitral objection.
