3.3. Right to be heard
In G 4/92, concerning the case of a decision taken against a party who has been duly summoned but fails to appear at oral proceedings, the Enlarged Board established that new evidence may not be considered unless it has been previously notified and merely supports the assertions of the party who submits it, whereas new arguments may in principle be used to support the reasons for the decision (G 4/92, OJ 1994, 149, headnote 2). For more on non-attendance at oral proceedings, see chapter III.C.5.
