The requirement of a "balanced representation" goes hand in hand with the additional provisos that the Commission is to take into account, other than considerations of gender and geographical origin, a group's specific tasks, the type of expertise required, as well as relevant areas of expertise and interest. Yet again, this strongly suggested that assessing whether a group benefits from a balanced representation is not simply an exercise in arithmetic, it being understood that expert groups are not entities deciding on a policy matter by casting a vote. Instead, in light of the different aspects which the Commission is to take into account when constituting an expert group, an assessment whether the composition of a group translates into a balanced representation could only be performed on a case-by-case basis. Such analysis also needs to take into account actual differences in the way different interest groups are organised.
