“Because the father’s challenge to the district judge’s jurisdiction, as articulated to this court, is that the threshold condition had not been met, his challenge is necessarily a challenge to her factual findings. The order that the district judge made is therefore an order of a kind which stands unless and until set aside or discharged by following the procedures contained in the Children Act and the Family Procedure Rules.”
“… a child living with foster parents under a care order is not detained but is simply living in the same type of domestic setting as any other child of their age would be. That is not the kind of detention at which the writ of habeas corpus is aimed.”
“The third point is more fundamental. Habeas corpus ad subjiciendum (which is the form of the writ with which I am concerned) is a remedy protecting the citizen or subject against an unlawful detention or imprisonment. Detention need not be at the hands of the state or public authority. Even a domestic house may for this purpose be a prison: see R v Jackson[1891] 1 QB 671 , [especially] per Lord Esher MR at p 682. That was the celebrated case where a wife who had been detained by her husband in his house, being given the full run of the house short of leaving it, was freed on a habeas corpus, the Court of Appeal denying that a husband has in law any right either to imprison or to confine his wife. But there must be a detention. The children in the present case are not in secure accommodation (whether in the sense in which that expression is used ins 25 of the Children Act 1989 or in any other sense). They are not being detained. They are simply living with foster parents in exactly the same type of domestic setting as any other children of their ages would be, whether living at home with their parents or staying with friends or relatives. Habeas corpus does not lie because a parent, or other person in loco parentis, makes it a rule that a child of tender years is not to leave the house unless accompanied by some suitable person or because an exasperated parent has sent a naughty child to his room and told him to stay there for two hours or because a rebellious teenager has been ‘grounded’ or subjected to a parentally enforced curfew, any more than habeas corpus lies if the headmaster of a boarding school forbids his charges to leave the school premises except at permitted times and for permitted purposes. And it makes no difference for this purpose that the domestic rule is actually enforced by the turning of a key in a lock.”
“A writ of habeas corpus will issue where someone is detained without any authority or the purported authority is beyond the powers of the person authorising the detention and so is unlawful. The remedy of judicial review is available where the decision or action sought to be impugned is within the powers of the person taking it but, due to procedural error, a misappreciation of the law, a failure to take account of relevant matters, a taking account of irrelevant matters or the fundamental unreasonableness of the decision or action, it should never have been taken. In such a case the decision or action is lawful, unless and until it is set aside by a court of competent jurisdiction.”
“The ground for doing so is that Parliament has put in place an adequate system for reviewing the merits of decisions made by district judges and it is not appropriate that there should be further review of these by the High Court.”
