1.An EIO may be issued in order to determine whether any natural or legal person subject to the criminal proceedings concerned holds or controls one or more accounts, of whatever nature, in any bank located in the territory of the executing State, and if so, to obtain all the details of the identified accounts.
2.Each Member State shall take the measures necessary to enable it to provide the information referred to in paragraph 1 in accordance with the conditions under this Article.
3.The information referred to in paragraph 1 shall also, if requested in the EIO, include accounts for which the person subject to the criminal proceedings concerned has powers of attorney.
4.The obligation set out in this Article shall apply only to the extent that the information is in the possession of the bank keeping the account.
5.In the EIO the issuing authority shall indicate the reasons why it considers that the requested information is likely to be of substantial value for the purpose of the criminal proceedings concerned and on what grounds it presumes that banks in the executing State hold the account and, to the extent available, which banks may be involved. It shall also include in the EIO any information available which may facilitate its execution.
6.An EIO may also be issued to determine whether any natural or legal person subject to the criminal proceedings concerned holds one or more accounts, in any non-bank financial institution located on the territory of the executing State. Paragraphs 3 to 5 shall apply mutatis mutandis. In such case and in addition to the grounds for non-recognition and non-execution referred to in Article 11, the execution of the EIO may also be refused if the execution of the investigative measure would not be authorised in a similar domestic case.
