Chen v Home Secretary

''Chen v Home Secretary'' was a decision of the European Court of Justice which decided that a minor who is a national of a European Union member state has the right to reside in the European Union with his or her third-country national parents, provided the minor and parents have health insurance and will not become a burden on the public finances of the member state of residence.

This case led to the Twenty-seventh Amendment of the Constitution of Ireland, which limited the constitutional right to Irish citizenship of individuals born on the island of Ireland to the children of Irish citizens and some others whose parents are not Irish citizens but who meet the prescribed criteria.
