Re: undocumented Pakistani family
Let see what Irish laws says about it :
If I m not mistaken there are no specific laws about the rights of residence of foreign parents of an Irish-born child. The non-national parents of such a child do not have a legal right to Irish citizenship. In such cases Non-EU parents of a child born in the Republic of Ireland or Northern Ireland must have to apply to the Minister for Justice if they wish to get residence in Ireland . Its totally in hands of minister, where is obliged to consider the principles in the Fajujonu judgement in making his decision. ( reference Supreme Court in the Fajujonu case 1990, incase if ya wana look up) If permission is granted then the parents must register with the Garda Siochana (police).
The law further says , the minister can review his decision if the applicant is not living with the child as part of a family unit and ceases to play a significant role in the upbringing of the child. So apnay Pakistan bahi shadiyan karkay bhaag nahe saktay :p
Then that common EU law kay , the minister might also review the permission to remain if he decides that the common good and the protection of the State and society justify interference with the parent's Constitutional family rights.
