“Article 3 The removal or retention of a child is to be considered wrongful where – (a) it is in breach of rights of custody attributed to a person, an institution or any other body, either jointly or alone, under the law of the state in which the child was habitually resident immediately before the removal or retention; and (b) at the time of removal or retention those rights were actually exercise, either jointly or alone, or would have been so exercised but for the removal or retention. The rights of custody mentioned in sub-paragraph (a) above, may arise in particular by operation of law or by reason of a judicial or administrative decision …… Article 13 Notwithstanding the provisions of the preceding Article, the judicial or administrative authority of the requested state is not bound to order the return of the child if the person, institution or other body which opposes its return establishes that – (a) the person, institution or other body having the care of the person of the child was not actually exercising the custody rights at the time of removal or retention, or had consented to or subsequently acquiesced in the removal or retention; or (b) there is a grave risk that his or her return would expose the child to physical or psychological harm or otherwise place the child in an intolerable situation ………”
“The ordinary and natural meaning of the words supplies one. For if there be proved a regular, habitual mode of life in a particular place, the continuity of which has persisted despite temporary absences, ordinary residence is established provided only it is adopted voluntarily and for a settled purpose. An attempt has been made in this case to suggest that education cannot be a settled purpose. I have no doubt it can be. A man’s settled purpose will be different at different ages. Education in adolescence or early adulthood can be as settled a purpose as a profession or business in later years. There will seldom be any difficulty in determining whether residence in voluntary or for a settled purpose: nor will inquiry into such questions call for any deep examination of the mind of the ‘propositus’.”
“Both courts also agreed in attaching decisive importance to what the Divisional Court called ‘the immigration status’ of the students. ‘Immigration status,’ unless it be that of one who has no right to be here, in which event presence in the United Kingdom is unlawful, means no more than the terms of a person’s leave to enter as stamped upon his passport. This may or may not be a guide to a person’s intention in establishing a residence in this country: it certainly cannot be the decisive test, as in effect the courts below have treated it. Moreover, in the context with which these appeals are concerned, i.e. past residence, intention or expectations for the future are not critical: what matters is the course of living over the past three years ………….. The relevant period is not the future but one which has largely (or wholly) elapsed, namely that between the date of the commencement of his proposed course and the date of his arrival in the United Kingdom. The terms of an immigrant student’s leave to enter and remain here may or may not throw light on the question: it will, however, be of little weight when put into the balance against the fact of continued residence over the prescribed period – unless the residence is itself a breach of the terms of his leave, in which event his residence, being unlawful, could not be ordinary.”
“1. The habitual residence of the young children of parents who are living together is the same as the habitual residence of the parents themselves and neither parent can change it without the express or tacit consent of the other or an order of the court. 2. Habitual residence is a term referring, when it is applied in the context of married parents living together, to their abode in a particular place or country which they have adopted voluntarily and for settled purposes as part of the regular order of their life for the time being, whether of short or of long duration. All that the law requires for a ‘settled purpose’ is that the parents’ shared intentions in living where they do should have a sufficient degree of continuity about them to be properly described as settled.”
