In exceptional cases, after having obtained the approval of the competent Permanent Chamber, the supervising European Prosecutor may take a reasoned decision to conduct the investigation personally, either by undertaking personally the investigation measures and other measures or by instructing the competent authorities in his/her Member State, where this appears to be indispensable in the interest of the efficiency to the investigation or prosecution by reasons of one or more of the following criteria: the seriousness of the offence, in particular in view of its possible repercussions at Union level; when the investigation concerns officials or other servants of the Union or members of the institutions of the Union; in the event of failure of the reallocation mechanism provided for in paragraph 3. In such exceptional circumstances Member States shall ensure that the European Prosecutor is entitled to order or request investigative measures and other measures and that he/she has all the powers, responsibilities and obligations of a European Delegated Prosecutor in accordance with this Regulation and national law. The competent national authorities and the European Delegated Prosecutors concerned by the case shall be informed without undue delay of the decision taken under this paragraph.
