[65831/26]

I propose to take Questions Nos. 883, 884, 885, 898, 907, 963 and 964 together.

The grounds for the revocation of citizenship are as set out in section 19 of the Irish Nationality and Citizenship Act 1956 (as amended).

Changes to this process were made by the Court, Civil Law, Criminal Law and Superannuation (Miscellaneous Provisions) Act 2024; these changes were required to address issues identified in a Supreme Court judgment that had found the then revocation process to be unconstitutional. Amendments to the process of revocation of citizenship came into effect from 7 April 2025 and the revised provisions can be found at http://revisedacts.lawreform.ie/eli/1956/act/26/section/19/revised/en/html

Under the new procedure, where the Minister for Justice, Home Affairs and Migration decides to revoke citizenship, they may do so under the five grounds set out in the 1956 Act. A notification of this intention is issued to the individual, who will be provided with the opportunity to make representations, and has 28 days to do so, before a decision is made to revoke their certificate of naturalisation.

Following receipt of those representations, or on expiry of the 28 days, if it is decided to proceed to revoke the certificate of naturalisation, then the individual has 14 days in which to request a Committee of Inquiry. Upon receipt of this request, I will appoint a Committee of Inquiry, which will be composed of a chairperson who will be a retired Judge of the Circuit Court, the High Court, the Court of Appeal, or the Supreme Court, and two ordinary members with appropriate experience and qualifications. The Committee of Inquiry will be independent in its function of inquiry into the Minister's decision and can either affirm the decision or set it aside.

In the last 10 years, 8 people have had their citizenship revoked, including two revocations since 7 April 2025.

The Deputy should note that a person can have their citizenship revoked on more than one ground under the Act.

Of the eight revocations, seven were made under section 19(1)(a) on the grounds that the issue of the certificate was procured by fraud, misrepresentation, whether innocent or fraudulent, or the concealment of material facts or circumstances.

One revocation was made under two grounds;

• section 19(1)(b) on the grounds that the person to whom it was granted had, by an overt act, shown themselves to have failed in their duty of fidelity to the nation and loyalty to the State.

• and/or section 19(1)(c) that (except in the case of a certificate of naturalisation which is issued to a person of Irish descent or associations) the person to whom it is granted has been ordinarily F59[resident outside the State or, in the case of an application for a certificate of naturalisation granted under section 15A, resident outside the island of Ireland] (otherwise than in the public service) for a continuous period of seven years and without reasonable excuse has not during that period registered annually in the prescribed manner his name and a declaration of his intention to retain Irish citizenship with an Irish diplomatic mission or consular office or with the Minister.

My Department actively reviews cases relating to terrorism, fraud, organised and serious crime with a view to assessing whether citizenship revocation proceedings are appropriate.

My Department does not maintain records in a format that would allow the information sought by the Deputy regarding custodial sentences, subsequent criminal convictions of naturalised citizens, or the specific circumstances in which citizenship revocation was considered but not pursued, to be readily extracted.

Similarly, my Department does not maintain records categorised in the manner requested by the Deputy in relation to marriages or civil partnerships with Irish citizens, marriages of convenience, or cases where citizenship applicants were subsequently found to have provided false, misleading or fraudulent information in immigration, residence, international protection or citizenship processes. Accordingly, the detailed information sought is not available.
