L'OLAF aide les institutions de l'UE à élaborer et à mettre en œuvre la législation et les politiques antifraude.

OLAF investigates a wide range of wrongdoings from embezzlement, fraudulent claims and misconduct in public procurement procedures, to customs fraud. Far from being an exhaustive list, these examples seek to illustrate different angles of OLAF’s investigative activity or different key moments in the lifespan of a case.
