Incapacity

First is the criterion of significantly impaired decision-making, required before a person can be made subject to compulsion under the Scottish Act. This caused considerable debate both in Parliament and in the Royal College of Psychiatrists in relation to the provisions for England and Wales. Those in favour argued that mental health law should mirror, as closely as possible, the legal provisions for people with physical illnesses. As was said by Dame Elizabeth Butler-Sloss in the case of Ms B ( B v. An NHS Hospital Trust [2002]),

It has been argued that we should not have any separate mental health legislation and that the mental capacity legislation, with perhaps some additional safeguards, should be the basis for all non-consensual treatment (Reference ZigmondZigmond, 1998; Reference Szmukler and HollowaySzmukler & Holloway, 1998). The proposals for Northern Ireland are in line with this approach. The College in England and Wales took the view, as had already been accepted in Scotland, that the criteria for determining capacity as set out in the Mental Capacity Act 2005 are too narrow for use with people with a mental disorder, being based largely, albeit not exclusively, on cognitive ability. It was argued that although a person who retains full decision-making ability should keep their personal autonomy, in order not to exclude from compulsion people with disorders of mood or abnormal thinking, the concept of significantly impaired decision-making by reason of mental disorder is a more appropriate test as a criterion for non-consensual treatment.

It was recognised, however, that any criterion pertaining to mental capacity may cause difficulty in relation to mentally disordered offenders. If a court determined that a mentally disordered person must be locked up then that person would not have the option of choosing voluntary admission to hospital. There would be a danger, if the impaired decision-making criterion applied to those who would be detained under Part 3 of the Mental Health Act 1983, that people who retained decision-making ability would have to go to prison even if they might benefit from admission to hospital. Hence the College's position that this criterion, significantly impaired decision-making, should apply only in relation to Part 2 detentions.

Those who argued against the impaired decision-making criterion did so on the basis that the appropriateness of compulsion should be determined solely on the basis of risk. If there is risk to the health or safety of the person or of other people then detention under the Mental Health Act should be an available option even if the person retains full decision-making ability. This was the position of the government in England and Wales but not the government in Scotland. The result is that people with mental disorders who retain full decision-making ability may be detained under a civil section in England and Wales but not in Scotland.

Compulsion exceeding 28 days

Second, the Scots have adopted a proposal that was in both the 2002 and 2004 draft mental health bills for England and Wales but abandoned when the government decided to amend the Mental Health Act 1983. That is, that all compulsion after 28 days, be it detention in hospital or compulsory treatment in the community, must be authorised by a mental health tribunal. This exceeds the requirements of Article 5 of the European Convention on Human Rights which, perhaps oddly, states that although anyone detained on the grounds of committing an offence must have an independent ‘hearing’ by a court, detained patients have a right to a ‘hearing’ only if they request one (so patients who are too ill or intellectually disabled to request an appeal, arguably the most vulnerable, do not have one for at least 6 months). Reference LyonsLyons (2008, this issue) suggests that the Scots may be having some difficulties with the resource requirements of this provision (which was the reason the proposal was not pursued in England and Wales).

Roles and responsibilities

The third major difference is that in Scotland the roles and responsibilities of different professional groups are largely unaltered. The Mental Health Act 2007, for England and Wales, enables clinical psychologists, mental health nurses, occupational therapists and social workers to take on the responsibilities of being in overall charge of patients' care and treatment. Particularly controversially, it also permits professionals who are not registered medical practitioners to provide the medical report required to renew detention orders. The European Court on Human Rights ( Winterwerp v. Netherlands [1979]) stated that ‘objective medical expertise’ is required to determine whether the patient has a mental disorder of a nature or degree to warrant detention. There is a question as to whether or not this can lawfully be provided by non-medical professionals. Parliament's Joint Committee on Human Rights, in its fourth report, stated,

How many non-medical professionals will wish to take up these roles and responsibilities is not known. Whether it is lawful will, no doubt, be decided by the courts.

Which country has the ‘better’ Act?

The scope for research, given the divergent pathways of different parts of the UK, is considerable. Whether one set of provisions turns out to be more effective, however this is to be measured, than another or whether they will be seen to be just different only time will tell. The Scots do, however, have one significant advantage. The principles behind the Scottish Act have met with universal approval from all stakeholders. The recently amended mental health act for England and Wales will need to demonstrate that it is ethical, workable and effective if it is to win over the hearts and minds of many of those who have to operate it, or will be subject to its provisions.
