Changes in the composition of an Opposition Division after oral proceedings should be generally avoided also in cases where no final substantive decision has been given orally. Where this is not possible, new oral proceedings must in general be offered to the parties under such circumstances (see the analogous regulation of Article 7(1) of the Rules of Procedure of the Boards of Appeal). Such offers may be foregone in exceptional cases, in particular if the final decision given by a differently composed Opposition Division is not substantially based on findings arrived at during the oral proceedings but on fresh facts and arguments communicated to the parties in the resumed written proceedings (see point 2.3 of the reasons).
