MC Inbound Arbitration

Overview

When an inbound arbitration case is received from the acquirer, this flow is executed.  A Review Inbound Arbitration assignment is generated and prompts a user to select from the following options:

• Accept the arbitration case and thereby financial responsibility for the disputed transaction.  The issuer can accept the arbitration case at any time before Mastercard rules on the case.  When this happens, the system generates an Arbitration Lost entry.

• Reject the arbitration case with a rebuttal and any relevant documentation that specifically addresses the information contained in the arbitration case filing within 10 calendar days of the arbitration case escalation date. Mastercard will not consider any information provided in arbitration that was required (but not provided) in the chargeback or arbitration chargeback.  Once the arbitration case is rejected, the case will then be available for Mastercard review as described in the Mastercard Review Process in the Mastercard Chargeback Guide.  The Mastercom Case Filing Application will allow the issuer to accept the arbitration case at any time before Mastercard rules on the case.  

• Take no action.  After 10 calendar days, the Mastercom Case Filing Application will automatically reject the arbitration case and the case will then be available for Mastercard review as described in the Mastercard Review Process section in the Mastercard Chargeback Guide.  The Mastercom Case Filing application will allow the issuer to accept the arbitration case at any time before Mastercard rules on the case.
