An arbitration clause drawn up in broad and all-encompassing terms, referring all disputes arising from the contract to arbitration, complies with the principle set out in art. 808 quater of the Code of Civil Procedure, according to which, in case of doubt, the arbitration agreement is to be interpreted as meaning that arbitral jurisdiction extends to all disputes arising from the contract or the relationship to which the agreement relates.
The existence of an arbitration clause does not preclude the jurisdiction of the ordinary court to issue a payment order, but requires the court, in the event of a subsequent opposition based on the existence of that clause, to declare the payment order void and to refer the dispute to the arbitrators.
