Regulation (EU, Euratom) No 883/2013 of the European Parliament and of the CouncilShow full title

Article 5 Opening of investigations

1. The Director-General may open an investigation when there is a sufficient suspicion, which may also be based on information provided by any third party or anonymous information, that there has been fraud, corruption or any other illegal activity affecting the financial interests of the Union. The decision by the Director-General whether or not to open an investigation shall take into account the investigation policy priorities and the annual management plan of the Office established in accordance with Article 17(5). That decision shall also take into account the need for efficient use of the Office’s resources and for proportionality of the means employed. With regard to internal investigations, specific account shall be taken of the institution, body, office or agency best placed to conduct them, based, in particular, on the nature of the facts, the actual or potential financial impact of the case, and the likelihood of any judicial follow-up.

2. The decision to open an external investigation shall be taken by the Director-General, acting on his own initiative or following a request from a Member State concerned or any institution, body, office or agency of the Union.

The decision to open an internal investigation shall be taken by the Director-General, acting on his own initiative or following a request from the institution, body, office or agency within which the investigation is to be conducted or from a Member State.

3. While the Director-General is considering whether or not to open an internal investigation following a request as referred to in paragraph 2, and/or while the Office is conducting an internal investigation, the institutions, bodies, offices or agencies concerned shall not open a parallel investigation into the same facts, unless agreed otherwise with the Office.

4. Within two months of receipt by the Office of a request as referred to in paragraph 2, a decision whether or not to open an investigation shall be taken. It shall be communicated without delay to the Member State, institution, body, office or agency which made the request. Reasons shall be given for a decision not to open an investigation. If, on the expiry of that period of two months, the Office has not taken any decision, the Office shall be deemed to have decided not to open an investigation.

Where an official, other servant, member of an institution or body, head of office or agency, or staff member, acting in accordance with Article 22a of the Staff Regulations, provides information to the Office relating to a suspected fraud or irregularity, the Office shall inform that person of the decision whether or not to open an investigation in relation to the facts in question.

5. If the Director-General decides not to open an internal investigation, he may without delay send any relevant information to the institution, body, office or agency concerned for appropriate action to be taken in accordance with the rules applicable to that institution, body, office or agency. The Office shall agree with that institution, body, office or agency, if appropriate, on suitable measures to protect the confidentiality of the source of that information and shall, if necessary, ask to be informed of the action taken.

6. If the Director-General decides not to open an external investigation, he may without delay send any relevant information to the competent authorities of the Member State concerned for action to be taken where appropriate, in accordance with its national rules. Where necessary, the Office shall also inform the institution, body, office or agency concerned.
