6.—(1) Every person born in the island of Ireland is entitled to be an Irish citizen.

(2) (a)  Subject to subsections (4) and (5), a person born in the island of Ireland is an Irish citizen from birth if he or she does, or if not of full age has done on his or her behalf, any act which only an Irish citizen is entitled to do.

(b)  The fact that a person so born has not done, or has not had done on his or her behalf, such an act shall not of itself give rise to a presumption that the person is not an Irish citizen or is a citizen of another country.

(3) A person born in the island of Ireland is an Irish citizen from birth if he or she is not entitled to citizenship of any other country.

(4) A person born in the island of Ireland—

(a) to a non-national who at the time of that person's birth was entitled to diplomatic immunity within the State, or

(b) to a non-national on a foreign ship or in a foreign aircraft,

shall not be an Irish citizen unless, in the prescribed manner, that person declares, or if not of full age has declared on his or her behalf, that he or she is an Irish citizen; and such person shall be deemed to be an Irish citizen from the date of birth or the date of coming into operation of this section, whichever is the later.

(5) A person born in the island of Ireland who has made a declaration of alienage under section 21 shall remain entitled to be an Irish citizen, but shall not be an Irish citizen unless, in the prescribed manner, that person declares that he or she is an Irish citizen; and such person shall be an Irish citizen from the date of the declaration.

Citizenship by descent.

7.—(1) A person is an Irish citizen from birth if at the time of his or her birth either parent was an Irish citizen or would if alive have been an Irish citizen.

(2) The fact that the parent from whom a person derives citizenship had not at the time of the person's birth done an act referred to in section 6(2)(a) shall not of itself exclude a person from the operation of subsection (1).

(3) Subsection (1) shall not confer Irish citizenship on a person born outside the island of Ireland if the parent through whom he or she derives citizenship was also born outside the island of Ireland unless—

(a) that person's birth is registered under section 27, or

Provided that the Irish citizenship of a person who, after 1 July, 1986, is registered under section 27 shall commence only as on and from the date of such registration.

(4) Nothing in this section shall confer Irish citizenship on a person not an Irish citizen immediately before its coming into operation, nor deprive of Irish citizenship a person who immediately before its coming into operation was an Irish citizen.”.
