‘[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.’
