The interaction of overlapping citizens rights and laws has led to some cases of exploitation of loopholes to avoid the intention of the law. For example, the Twenty-seventh Amendment of the Constitution of Ireland was required to amend the potential for abuse of the rights of Irish citizenship to the right to abode in the United Kingdom. Before then, Irish citizenship was granted on the basis of "jus soli" (i.e. being born on the island of Ireland was reason in itself to be considered an Irish citizen). In one case, a Chinese migrant to the UK, living in Wales on Great Britain, chose to give birth to a child in Northern Ireland, on the island of Ireland, to take advantage of Irish citizenship laws. Consequently, her child was born an Irish citizen by virtue of "jus soli" and so was entitled to permanent abode in the UK even though the mother did not have the right to visit the Republic of Ireland. The mother and father then claimed the right to stay in the United Kingdom by virtue of being the guardians of a citizen of the European Union who would be unable to look after itself should they be deported.
