The Court of Appeal dismissed X.P.’s appeal concerning the refusal of his application for Irish citizenship by naturalisation, holding that the decision did not implement European Union law and that the EU Charter did not apply. The judgment, delivered by Mr Justice Hogan on 18 April 2018, adopts the conclusions of Mr Justice Gilligan, whose fuller account of the facts is not included in this source.
X.P., who was born outside Ireland, sought naturalisation under section 15 of the Irish Nationality and Citizenship Act 1956. Hogan J. recorded that the Minister relied on material said to concern sensitive national-security matters, which X.P. had not seen. He described this as unfair and in tension with fair procedures, but said the circumstances were exceptional and involved national security and sensitive diplomatic channels.
A separate, unappealed High Court decision by McDermott J. had reviewed the relevant documents and ruled that the Minister could claim public-interest immunity over key parts. Hogan J. said that finding established real and pressing national-security concerns. The Court of Appeal concluded that releasing the material, even in redacted or summary form, was not practicable. Hogan J. also said the judiciary could not create a system of security-vetted special counsel to review such material.
X.P.’s other major submission was that refusing naturalisation implemented EU law, engaging Charter rights to good administration, access to the file and an effective remedy. The court rejected that argument. Hogan J. reasoned that naturalisation is an executive exercise of national sovereignty under the Irish Constitution and the 1956 Act. Although citizenship of an EU member state also brings EU citizenship, he said determining who receives national citizenship remains, in principle, for that state.
The judgment distinguished the EU Court of Justice’s decision in Rottmann, which concerned withdrawal of nationality with consequences for EU rights. X.P. had never been an Irish or EU citizen, Hogan J. said, so refusal of his application did not affect rights protected by EU law. The court held that neither the Charter nor EU law applied to the Minister’s decision.
