The Commission relied on the applicable case-law of the Court of Justice of the European Union, and Article 85 of the Staff Regulations, which do not exclude an administration from the possibility of claiming back amounts which it may have paid out by mistake.The above case-law should not, however, be interpreted as giving permission for administrative mistakes to be made. In the present case, the Commission made repeated administrative mistakes. The Commission certainly did not act in a way which is to be expected from an institution committed to good administration. Rather, its actions could come across as disproportionate and inconsistent and thus reinforce a provisional finding of maladministration.
