Scaled down

Liberty is important, not least for the safeguards that take its name, but what does the word mean?

The Deprivation of Liberty Safeguards (DoLS) are intended to protect incapable people admitted to hospitals or registered care homes. As the title suggests, they say that permission will be required before such people can be deprived of liberty. Given the importance of the notion, you might imagine that ‘deprivation of liberty’ is carefully explained. It isn’t: the DoLS use the term but don’t define it, and the accompanying code of practice says little that is original. In fact, the code simply restates the existing law, which might be where the problems begin.

The DoLS seek to remedy defects identified by the European Court of Human Rights (ECtHR) in the Bournewood case. Those were defects in the common law, which the court said was too vague and too lacking in procedural safeguards to give many incapable people the protection demanded by the ECHR (HL v United Kingdom [2004] 40 EHRR 761).

The defects would only be apparent where Article 5 of the Convention was engaged; where, in other words, someone was deprived of liberty. The ECtHR said, “the starting-point must be the concrete situation of the individual concerned”, and that in deciding whether a particular intervention deprives someone of liberty, “account must be taken of a whole range of factors arising in a particular case[,] such as the type, duration, effects and manner of implementation of the [intervention] in question.” Crucially, the court said the distinction between deprivation of liberty, which will engage Article 5, and a mere restriction upon liberty, which will not, “is merely one of degree or intensity and not one of nature or substance” (HL v United Kingdom, above, paragraph 89). These words have proved extremely resonant.

The DoLS code draws heavily upon Bournewood. Noting the comments of the ECtHR on the crucial distinction, the code says: “It may therefore be helpful to envisage a scale, which moves from ‘restraint’ or ‘restriction’ to ‘deprivation of liberty’. Where an individual is on the scale will depend on the concrete circumstances of the individual and may change over time.”

There are, however, several problems with the ‘scale’ theory of deprivation of liberty. The first concerns its range: rather than with ‘restriction of liberty’, which surely comes some way along, shouldn’t the scale begin with ‘liberty’ itself? 

Logically, of course, there must be a number of points on the scale, each one representing a particular intervention in a patient’s life, from those that represent only a slight diminution of liberty to those that approach deprivation of liberty. But the number of possible interventions is not fixed; new ones might be made from-time-to-time, and any of them might be modified in numberless ways. The second problem, therefore, is that we can never know precisely how to populate our scale. Imagining, as it seems we must, that the poles represent complete liberty and its deprivation, where on that scale are the various interventions to be placed, and, crucially, where in relation to each other? Is putting someone in a low chair closer to deprivation of liberty than to liberty, for example, and how does it stand in relation to shepherding someone away from an open door?

The third problem relates to something else said by the code: when deciding whether someone is deprived of liberty, we might ask “does the cumulative effect of all the restrictions … amount to a deprivation of liberty, even if individually they would not?” This begs an obvious question: if all we have is the scale, on which single interventions are placed side-by-side, how are we to take account of the aggregate of two or more of them? How, in fact, are we to aggregate them at all, and even if we succeed in doing so, where precisely are we to place the aggregated intervention? Is shepherding someone away from an open door closer to deprivation of liberty than putting him in a low chair and reducing the length of his visits from friends? How will the scale help us decide?

Finally, of course, there is a problem inherent in the very notion of a scale. All it does is display subtle progressions between two points, so it cannot help us with the DoLS. The knowledge that the use of ‘baffle locks’ tends rather more to the right-hand end than to the left is worthless. When what we most require is a ‘yes/no’ answer, the scale is deliberately designed to yield no such thing.

If, as seems to be the case, there is widespread confusion about what it means for someone to be deprived of liberty, the Code of Practice only serves to compound the problem. It advances a ‘scale’ theory that is both logically and logistically flawed, and in so doing, it misrepresents the problem it purports to have solved.
