The Committee comprises 5 independent outside experts (with the qualifications required in their respective countries for senior posts relating to OLAF's work) appointed by common agreement of the European Parliament, the Council and the Commission for 5 years.
Members are independent and may neither seek nor take instructions from any government or any institution, body, office or agency.
The Supervisory Committee is supported in its work by its own Secretariat consisting of lawyers, investigators and assistants carrying out the daily monitoring of OLAF's investigative activities. The Secretariat, whilst situated within the structure of OLAF, functions independently and under the instructions of the Supervisory Committee as outlined in its Rules of Procedure.
OLAF's Supervisory Committee was established to reinforce and guarantee OLAF’s independence by regularly monitoring the implementation of OLAF's investigative function.
The Supervisory Committee delivers opinions to the OLAF Director General at the request of the Director or on its own initiative concerning OLAF's activities without, however, interfering with the conduct of investigations in progress.
The Supervisory Committee delivers a yearly opinion on the preliminary draft budget submitted by OLAF.
