Article 4 5.

In a validly established emergency case, as defined in Article 3, point (18), the competent authorities referred to in paragraph 1, point (b), and in paragraph 3, point (b), of this Article may exceptionally issue a European Production Order for subscriber data or for data requested for the sole purpose of identifying the user as defined in Article 3, point (10), or a European Preservation Order, without prior validation of the order concerned, where validation cannot be obtained in time and where those authorities could issue an order in a similar domestic case without prior validation. The issuing authority shall seek ex post validation of the order concerned without undue delay, at the latest within 48 hours. Where such ex post validation of the order concerned is not granted, the issuing authority shall withdraw the order immediately and shall delete or otherwise restrict the use of any data that were obtained.
