欧州不正対策局
欧州不正対策局は欧州委員会の総合サービス部門の一部局であるが、調査活動に関しては完全に独立した立場で任務にあたる。2005年7月の特別報告書において、欧州会計監査院は次のように報告している。
"the hybrid status of the Office, which has investigative autonomy but reports to the Commission for its other duties, has not adversely affected the independence of its investigative function. Being part of the Commission, the Office has been able not only to benefit from substantial administrative and logistical support, but also to take advantage of the anti-fraud legislation that is available to Commission departments"
