Post-2005 Irish/Entitled-Parent Jus Soli (s.6A(2) exemption)
Citizenship in Ireland
- Eligibility
- A child born in the island of Ireland (incl. Northern Ireland) on or after 1 Jan 2005 is an Irish citizen automatically from birth (INCA 1956 s.6(1)) where at least one parent, at the time of birth, falls within an s.6A(2) exemption: s.6A(2)(b) Irish citizen or entitled to be; (c) British citizen or entitled to reside in NI without restriction; (d) entitled to reside in the State without restriction. Any limb disapplies the s.6A(1) 3-of-4-years residence test. Acquisition is automatic, lifelong, with no application, fee, oath or discretion; status is declaratory and self-proving by passport (s.6(2)(a)). No diplomatic-immunity exemption exists.

Who qualifies
A child qualifies under IE-BTH-02 where: (1) born in the island of Ireland — a phrase the Constitution (Art 9.2.1, verbatim) defines as 'which includes its islands and seas', capturing Northern Ireland and the surrounding waters; the Art 2 birthright reinforces island-wide reach — on or after 1 January 2005 (commencement S.I. 873/2004 commencing INCA 2004 s.4); AND (2) at least one parent, at the time of birth, falls within a RELIEVING s.6A(2) limb: s.6A(2)(b) parent is an Irish citizen or entitled to be; s.6A(2)(c) parent is a British citizen (UK citizen per s.6A(3)) or entitled to reside in Northern Ireland without any restriction on period of residence; s.6A(2)(d) parent entitled to reside in the State without any restriction. Where any relieving limb (b),(c) or (d) is met, the s.6A(1) '3 of the 4 years preceding birth' parental-residence condition does NOT apply — that disapplication is the route's entire function. The remaining s.6A(2) paragraphs are (a) pre-2005 births (route IE-BTH-03) and (e), which is NOT a relieving limb but an EXCLUSION (a child of a diplomatically-immune parent within Immigration Act 2004 s.2(1)/s.2(1A), otherwise unqualified, is DENIED entitlement). Boundary: this is the relieving-exemption set, distinct from the s.6A(1) residence-reckoning route IE-BTH-01 (governed by s.6B reckoning and UM [2022] IESC 25). There is no diplomatic-immunity RELIEVING exemption in s.6A(2) (VC-IE-jus_soli_s6-01); births before 1 Jan 2005 fall under the unconditional route IE-BTH-03.
How to apply
There is no 'application to acquire' citizenship under IE-BTH-02 — entitlement arises by operation of law at birth. The procedural dimension is proof/operationalisation of an existing status, not a grant, exercised by doing (or having done on the child's behalf) an act only an Irish citizen may do under s.6(2)(a) — paradigmatically a parent applying for the child's Irish passport. Authority split (LOCKED): documentary proof of citizenship is handled by the Department of Foreign Affairs (DFA) / Minister for Foreign Affairs (passport issuance; s.28 certificate-of-nationality machinery); naturalisation and revocation (irrelevant here) sit with the Minister for Justice via ISD, functions transferred by S.I. 418/2011. Practical steps: (1) child's long-form civil birth certificate showing island-of-Ireland birth on/after 1 Jan 2005; (2) evidence a parent fell within s.6A(2)(b),(c) or (d) at birth (parent's Irish passport/FBR entry, British passport/unrestricted-NI-residence proof, or unrestricted-State-residence proof); (3) lodge the Irish passport application as the citizen-only act. Fees/timelines [NUMERICAL]: no statutory acquisition fee — not naturalisation (no EUR 950 certification fee) and not FBR descent registration (the EUR 278 adult / EUR 153 minor FBR fees and ~12-month FBR processing do NOT apply; those govern IE-DSC-02). Only the ordinary DFA passport fee applies.
Legal basis
IE-BTH-02 is the post-2005 entitled-parent jus soli pathway. The conferring entitlement is INCA 1956 s.6(1) ('every person born in the island of Ireland is entitled to be an Irish citizen', expressly subject to s.6A). The post-2005 default in s.6A(1) denies entitlement unless a parent was resident in the island for >=3 of the 4 years before birth; s.6A(2) lifts that condition for defined parental categories. The relieving exemption paragraphs that constitute this route are s.6A(2)(b) (parent who is an Irish citizen or entitled to be), s.6A(2)(c) (parent who is a British citizen, or entitled to reside in Northern Ireland without restriction), and s.6A(2)(d) (parent entitled to reside in the State without restriction). 'British citizen' = UK citizen per s.6A(3). The full s.6A(2) set also contains (a) (pre-2005 births = IE-BTH-03 grandfather) and (e), which is NOT a relieving limb but an EXCLUSION trigger — a child neither of whose parents was Irish/British/unrestricted-resident and at least one of whose parents is a person referred to in Immigration Act 2004 s.2(1)/s.2(1A) (the modernised diplomatic-immunity reference substituted into (e)(ii) by Act 33/2017 s.9(b), eff. 13 Dec 2017). Constitutional frame: Art 9.2.1 (27th Amendment 2004, enacted 24 Jun 2004) limits jus soli 'unless provided for by law' — s.6A(2) is that provision. (VC-IE-jus_soli_s6-01): there is NO diplomatic-immunity RELIEVING exemption in s.6A(2) — the diplomatic element is the (e) exclusion (and, for births 2 Dec 1999-31 Dec 2004, the former-s.6(4) exclusion + special-declaration route), neither relieving the residence condition; v1's non-existent 'INCA 1956 s.6(1)(a)(b)' sub-lettering re-cited to the exact s.6A(2)(b)-(d) relieving paragraphs.
Competent authority
Primary operational authority — DFA (Minister for Foreign Affairs): because IE-BTH-02 produces a birthright status (not a granted status), the only body a member of this cohort ordinarily engages is the DFA Passport Service, which issues the passport operationalising the s.6(2)(a) declaratory act and is the principal documentary proof of citizenship. The DFA also maintains the s.28 certificate-of-nationality machinery for formal status determinations, and (where the qualifying parent acquired citizenship by descent) the Foreign Births Register records evidencing the s.6A(2)(b) 'entitled to be an Irish citizen' parental limb. Minister for Justice / ISD has NO decision-making role in acquisition under this route — acquisition is automatic at birth and there is no 'absolute discretion' of the s.15/s.16 naturalisation kind (S.I. 418/2011 transferred naturalisation functions to Justice; descent/passport remained with Foreign Affairs). Do not normalise these into a single authority. ISD relevance is confined to border/immigration administration and to immigration-status records bearing on the limbs (c)/(d) unrestricted-residence questions. Courts / challenge: no statutory grant decision to appeal; disputes (whether a parent fell within s.6A(2)(b)-(d) at birth, or whether the s.6A(1) residence test was instead engaged) are resolved by judicial review in the High Court with declaratory relief, potentially via the s.28 certificate process. UM (a minor) v Minister for Foreign Affairs [2022] IESC 25 clarified the adjacent s.6A/s.6B conditional-jus-soli mechanism.
Example scenarios
eligible
Post-2005 birth, but the s.6A(1) residence requirement does NOT apply where a parent is entitled to reside in the State without restriction — s.6A(2)(d). An EU citizen exercising treaty rights falls within the unrestricted-residence exemption, so the child is entitled under s.6(1) without any 3/4-year reckoning. [Pins: A-JS-05; INCA 1956 s.6A(2)(d)]
eligible
Post-2005 birth, but exemption under s.6A(2)(c) applies where a parent is a British citizen (defined in s.6A(3) as a citizen of the UK of GB & NI). The 3/4-year residence test is disapplied; the child is entitled under s.6(1). [Pins: A-JS-05, A-JS-06; INCA 1956 s.6A(2)(c), s.6A(3)]
