The value of the claim for the purposes of determining arbitral jurisdiction is established at the time of filing the claim, with subsequent reductions of credit claims made during the proceedings remaining irrelevant, even when the debtor invokes the arbitration clause in opposition to an order for payment.
Opposition proceedings against an order for payment constitute a mere continuation of the summary payment procedure and not an autonomous process, so that the value of the dispute for the application of the arbitration clause must be determined on the basis of the credit claim originally advanced in the summary payment application, regardless of subsequent modifications of the conclusions.
