A COUPLE have asked the High Court to overturn the refusal of the Adoption Authority of Ireland (AAI) to recognise their adoption of a young Mexican girl.
The judicial review proceedings could affect 19 other adoptions of Mexican children by Irish citizens.
The case was initiated last April when the couple secured leave to bring the challenge.
The central issue is whether the adoption was required to meet with requirements of the Hague Convention on the Protection of Children, dealing with inter-country adoptions.
Daithi MacCarthaigh, counsel for the parents, said there was no dispute this couple were suitable to adopt the child and that they had stayed in Mexico for about six months until the adoption was finalised.
When they returned to Ireland with the child in March 2011, they were told the AAI could not recognise the adoption because it did not meet requirements of the Hague Convention.
The couple contended the Hague Convention did not apply to this adoption because the Convention was not Irish law when this adoption was being arranged.
A letter from the Mexican embassy referred to the children as "victims" and urged they remain in Ireland and that a solution be found.
The case continues.
