It has been the practice of some parties not to attend at Oral Proceedings, without informing any of the other parties, so as to ensure maximum inconvenience to their competitors who go to the expense and time of attending such Oral Proceedings. This point was dealt with in the Technical Board of Appeal Decision No. T930/92 (Hitachi Limited / ICT Integrated Circuit Testing Gesellschaft für Halbleiterprüftechnik mbH). In that particular case, the Appellant did not appear at the Oral Proceedings and did not inform any party of their non-attendance. In the circumstances of this particular case, if they had known of the non-attendance at Oral Proceedings, the Board would have cancelled the Oral Proceedings and awarded the case to the other party. Therefore, because both the Board and the other party had been forced to attend Oral Proceedings which were unnecessary, costs were awarded against the party who decided not to attend the Oral Proceedings without informing any of the other parties.
