"The activities mentioned by Mr Carl as part of his tasks at KGA included “strategic consulting on international economic relations including energy issues” and his employment at Kreab (as a lobbyist / lobbying adviser, including on energy issues) is clearly related to the work he has carried out during his recent time at the Commission. CEO considers that the Commission could – and should - have introduced a cooling off period or ban for 2 years before allowing Mr Carl's job move. In April 2010, CEO complained to the Commission about this case and the extent to which Article 16 had been fully applied. The Commission rejected the complaint."
