In D 9/17 the DBA confirmed that the Rules relating to Fees applied, at least mutatis mutandis, to the payment of the fee for an appeal lodged under Art. 24(2) REE. This fee was to be paid by payment or transfer to a bank account held by the Office (Art. 5(1) RFees). In the case in hand, there were no allowable alternative methods; in particular, payment of the fees according to Art. 17 REE by debit order was not provided for in the Arrangements for deposit accounts.
