1.

Are Articles 27 and 32 of Directive 2004/38/EC (1) to be interpreted, in the light of Articles 45 and 49 TFEU, and having regard to the procedural autonomy of the Member States and the principles of protection of legitimate expectations and good administration, as meaning that the withdrawal of a certificate of registration as a European Union citizen, previously granted, under Article 8(1) of [Greek] Decree 106/2007, to a national of another Member State, and the imposition on him of a measure for his removal from the host Member State, is required or permitted in circumstances where, although he had been registered in the national list of undesirable aliens and was the subject of an exclusion order on grounds of public policy and public security, that person again entered the Member State concerned and conducted a business, while failing to observe the procedure laid down in Article 32 of Directive 2004/38 for the submission of an application for the lifting of that exclusion order, when the latter (the exclusion order) was imposed on the self-sufficient ground of public policy which justifies the withdrawal of the certificate of registration of a citizen of a Member State?

2.

In the event of an affirmative answer to the first question, are such circumstances to be treated in the same way as circumstances where a European Union citizen is staying illegally in the territory of the host Member State, so that it is permissible, pursuant to Article 6(1) of Directive 2008/115/EC, (2) for the body which is competent to withdraw the certificate of registration as a Union citizen to issue a return order, given that (i) the registration certificate does not constitute, as is well established, evidence of a right of legal residence in Greece, and (ii) only third county nationals fall within the scope ratione personae of Directive 2008/115/EC?

3.

In the event of a negative answer to the first question, if the competent national authorities, acting within the framework of the procedural autonomy of the host Member State, were to withdraw, on grounds of public policy and public security, the registration certificate of a citizen of another Member State, which does not constitute evidence of a right of legal residence in Greece, and simultaneously impose, on that citizen, an order to return, could that be considered to involve, according to the correct legal classification, one and the same administrative act concerning administrative expulsion under Articles 27 and 28 of Directive 2004/38 subject to judicial review under the conditions laid down in those provisions, which lay down what is possibly the sole means of administrative removal of EU citizens from the territory of the host Member State?

4.

In the event that the answer to the first and second questions referred for a preliminary ruling is either affirmative or negative, is national legal practice compatible with the principle of effectiveness if that practice prohibits administrative authorities and thereafter courts with jurisdiction, which are seised of a case, from undertaking an examination, in the context of the withdrawal of a certificate of registration of a Union citizen or the imposition of a measure for the removal from the host Member State on the grounds of the continuing validity of an order excluding the national of another Member State from the Member State concerned, of the extent to which the procedural safeguards of the provisions in Articles 30 and 31 of Directive 2004/38 were observed in the issue of the exclusion order concerned?

5.

In the event of an affirmative answer to the fourth question, does it follow from Article 32 of Directive 2004/38 that the competent administrative authorities of the Member State are obliged to notify, in all cases, the national of another Member State concerned of the decision ordering his removal in a language which he understands, so that he is in a position properly to exercise the legal rights which he derives from the provisions concerned of the directive, irrespective of whether the relevant application has been submitted by him?
