Where a taxable person stores invoices which he issues or receives by electronic means guaranteeing on-line access to the data and where the place of storage is in a Member State other than that in which he is established, the competent authorities in the Member State in which he is established shall, for the purposes of this Directive, have the right to access those invoices by electronic means, to download and to use them, within the limits set by the rules of the Member State in which the taxable person is established and in so far as those authorities require for control purposes.
