Where measures executed on national territory pursuant to a European Investigation Order could, if they had been executed in the context of a national procedure, have been the subject of a challenge, an application for a declaration of nullity or any other form of appeal pursuant to the provisions of this Code, such appeals may, under the same conditions and in accordance with the same procedures, be lodged against these measures by the persons concerned. Such persons shall be informed of their right to lodge such appeals where such information is provided for by the provisions of this Code.
Such appeals shall not suspend the execution of the investigation measure, unless such suspension is provided for by the provisions of this Code.
Such appeals may not be based on the substantive grounds on which the European Investigation Order was issued, which may only be challenged by an action brought in the issuing State.
Failure to comply with the time limits for execution of the European investigation request cannot constitute a ground for invalidity of the acts performed.
