Where a decision of the examining division depended entirely on the outcome of proceedings before the Enlarged Board of Appeal on a legal question or point of law raised under Art. 112 EPC 1973 and this was known to the examining division the further examination of the application had to be suspended until the matter had been decided by the Enlarged Board of Appeal. Failure to do so amounted to a substantial procedural violation under R. 67 EPC 1973 (T 166/84, OJ 1984, 489). R. 103(1)(a) EPC now takes up the text of R. 67 EPC 1973, first sentence. See also T 426/00.
