"RIGHT TO LIBERTY AND SECURITY 1. Everyone has the right to liberty and security of person. No one shall be deprived of his liberty save in the following cases and in accordance with a procedure prescribed by law: … (e) the lawful detention of persons for the prevention of the spreading of infectious diseases, of persons of unsound mind, alcoholics or drug addicts or vagrants; … 4. Everyone who is deprived of his liberty by arrest or detention shall be entitled to take proceedings by which the lawfulness of his detention shall be decided speedily by a court and his release ordered if the detention is not lawful. 5. Everyone who has been the victim of arrest or detention in contravention of the provisions of this Article shall have an enforceable right to compensation."
"…the sole end for which mankind are warranted, individually or collectively in interfering with the liberty of action of any of their number, is self-protection. That the only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant."
"…this doctrine is meant to apply only to human beings in the maturity of their faculties … Those who are still in a state to require being taken care of by others, must be protected against their own actions as well as against external injury."
"76. While there is a subjective element in the exercise of ascertaining whether one's liberty has been restricted, this is to be determined primarily on an objective basis. Restriction or deprivation of liberty is not solely dependent on the reaction or acquiescence of the person whose liberty has been curtailed. Her or his contentment with the conditions in which she finds herself does not determine whether she is restricted in her liberty. Liberty means the state or condition of being free from external constraint. It is predominantly an objective state. It does not depend on one's disposition to exploit one's freedom. Nor is it diminished by one's lack of capacity. 77. The question whether one is restricted (as a matter of actuality) is determined by comparing the extent of your actual freedom with someone of your age and station whose freedom is not limited. Thus a teenager of the same age and familial background as MIG and MEG is the relevant comparator for them. If one compares their state with a person of similar age and full capacity it is clear that their liberty is in fact circumscribed. They may not be conscious, much less resentful, of the constraint but, objectively, limitations on their freedom are in place. 78. All children are (or should be) subject to some level of restraint. This adjusts with their maturation and change in circumstances. If MIG and MEG had the same freedom from constraint as would any child or young person of similar age, their liberty would not be restricted, whatever their level of disability. As a matter of objective fact, however, constraints beyond those which apply to young people of full ability are – and have to be – applied to them. There is therefore a restriction of liberty in their cases. Because the restriction of liberty is – and must remain – a constant feature of their lives, the restriction amounts to a deprivation of liberty. 79. Very young children, of course, because of their youth and dependence on others, have – an objectively ascertainable – curtailment of their liberty but this is a condition common to all children of tender age. There is no question, therefore, of suggesting that infant children are deprived of their liberty in the normal family setting. A comparator for a young child is not a fully matured adult, or even a partly mature adolescent. While they were very young, therefore, MIG and MEG's liberty was not restricted. It is because they can – and must – now be compared to children of their own age and relative maturity who are free from disability and who have access (whether they have recourse to that or not) to a range of freedoms which MIG and MEG cannot have resort to that MIG and MEG are deprived of liberty."
