Application of security regulations
Article 4
1. Each Member State shall ensure that its national security regulations offer a degree of protection of classified information at least equivalent to that provided by the rules on security as set out in the Annex to Decision 2001/844/EC, ECSC, Euratom and by Decision 2011/292/EU and that those national security regulations apply to its PRS users and to all natural persons resident on its territory and all legal persons established on its territory which handle EU classified information relating to the PRS. 2. Member States shall inform the Commission without delay of the adoption of national security regulations as referred to in paragraph 1. 3. If it emerges that EU classified information relating to the PRS has been disclosed to any person not authorised to receive it, the Commission shall, in full consultation with the Member State concerned: (a) inform the originator of the classified PRS data; (b) assess the potential damage caused to the interests of the Union or of the Member States; (c) notify the appropriate authorities of the results of that assessment accompanied by a recommendation to remedy the situation, in which case the appropriate authorities shall inform the Commission without delay of the action they intend to take or have already taken, including action aimed at preventing recurrence, as well as of the results of such action; and (d) inform the European Parliament and the Council, as appropriate, of those results.
