Brokers can revoke tariffs they previously published any time during the competition. The accounting service then removes the respective tariff from the PublishedTariffList. Consquently, upon the next timeslot change, the list of all published tariffs does not contain the respective tariff anymore.

• Broker

• Involved: Br-As
• A RevokeTariffCommand enters the server as JMS message with XML payload from a broker. It is then unmarshalled into a RevokeTariffCommand object (see below) and the broker credentials are validated (authentication). The RevokeTariffCommand is then forwarded to the AccountingService, which removes the respective tariff from the PublishedTariffList. When this list is sent out to the public upon the next timeslot change, the revoked tariff is no longer included.
