The questions referred to the Court:

-Are national legislation and case-law consistent with Article 14 of Directive 2014/41/EU (1) regarding the European Investigation Order in criminal matters, in so far as they preclude a challenge, either directly as an appeal against a court decision or indirectly by means of a separate claim for damages, to the substantive grounds of a court decision issuing a European investigation order for a search on residential and business premises and the seizure of specific items, and allowing examination of a witness?

-Does Article 14(2) of the directive grant, in an immediate and direct manner, to a concerned party the right to challenge a court decision issuing a European investigation order, even where such a procedural step is not provided for by national law?

-Is the person against whom a criminal charge was brought, in the light of Article 14(2) in connection with Article 6(1)(a) and Article 1(4) of the directive, a concerned party, within the meaning of Article 14(4), if the measures for collection of evidence are directed at third party?

-Is the person who occupies the property in which the search and seizure was carried out or the person who is to be examined as a witness a concerned party within the meaning of Article 14(4) in connection with Article 14(2) of the directive?

In its judgment the CJEU states that

“…the referring court is asking, in essence, whether Article 5(1) of Directive 2014/41, read in conjunction with Section J of the form referred to in Annex A to that directive, must be interpreted as meaning that the judicial authority of a Member State must, when issuing an EIO, include in that section a description of the legal remedies, if any, which are provided for in its Member State against the issuing of such an order”.

The Court rules that
Article 5(1) of Directive 2014/41/EU of the European Parliament and of the Council of 3 April 2014 regarding the European Investigation Order in criminal matters, read in conjunction with Section J of the form set out in Annex A to that directive, must be interpreted as meaning that the judicial authority of a Member State does not, when issuing a European Investigation Order, have to include in that section a description of the legal remedies, if any, which are provided for in its Member State against the issuing of such an order.
