P. Nikiforos Diamandouros, the European Ombudsman, reported that the overall rate of compliance by the EU institutions with his suggestions was 82% in 2011. The best performers were the EU Agencies with a 100% compliance rate.

Two studies presented by the European Ombudsman, P. Nikiforos Diamandouros, report that in 2011, the overall rate of compliance by the EU institutions with his suggestions was 82%. The best performers were the EU Agencies with a 100% compliance rate. These results are among the follow-up given by the EU administration to the 120 recommendations, remarks, and friendly solution proposals issued by the Ombudsman in 2011, of which 98 received a positive response from the institution concerned. In 2010, the European Ombudsman received a positive reply from the EU institutions in 78% of cases.

With regard to the positive responses, in 2011, the Ombudsman's recommendations, remarks, and friendly solution proposals concerned matters such as unjustified refusal to give access to documents, problems with tender procedures, conflicts of interest, and infringement of the right to be heard.

On the negative responses, one example of an unsatisfactory response concerned lack of transparency in an EPSO competition. In another case, the Commission did not follow the Ombudsman's advice on how to facilitate access to document requests. The compliance rate of the European Commission according to the studies, was the same as the overall figure of 82%, while the European Personnel Selection Office (EPSO) scored 69%.
