In the event of interlocutory revision, reimbursement of appeal fees will be ordered by the department whose decision has been impugned if such reimbursement is equitable by reason of a substantial procedural violation. This is particularly the case when essential facts or evidence were not taken into consideration in arriving at a decision, e.g. where a document filed at the EPO in good time by the party concerned is not placed in the file before a decision is reached or where the decision is based on facts or evidence on which the party concerned had no opportunity of presenting his comments. The appeal fee is to be reimbursed, even if this was not explicitly requested by the appellant (see G 3/03).
If the decision is rectified by an interlocutory revision not because of any substantial procedural violation but e.g. because the party concerned submits amendments at the time of filing the appeal, there will be no reimbursement of appeal fees.
If the department whose decision is contested considers the requirements of Art. 109 for interlocutory revision to be fulfilled, but not the requirements of Rule 103(1)(a) for reimbursement of the appeal fee, it must rectify its decision and remit the request for reimbursement of the appeal fee to the board of appeal for a decision (see J 32/95).
