In T 248/92, the examining division had based its decision on arguments submitted for the first time during oral proceedings. The board held that the examining division's decision had not been taken contrary to Art. 113(1) EPC 1973. Although one of the purposes of oral proceedings was to settle as far as possible all outstanding questions relevant to a decision, they did not have a constraining effect in the sense of requiring an immediate decision to be taken at the end of those proceedings. If the appellant had felt the need for further reflection, he could have asked for the oral proceedings to be adjourned or for the proceedings to be continued in writing so that he could study carefully the newly introduced arguments, which were obviously crucial to the decision.
