Assisted Dying Bill [HL]

Debate between Viscount Colville of Culross and Lord Swinfen

Friday 7th November 2014 Lords Chamber

[Viscount Colville of Culross (CB)]

My Lords, I have put my name to Amendment 66 because, as I said at Second Reading, I am concerned that there are not sufficient safeguards in the Bill to ensure that the mental capacity of the terminally ill person has been correctly assessed.

In subsection (2) of the proposed new clause, the emphasis is on the doctor not to countersign the declaration of intention,

“Unless the attending doctor is satisfied that a person requesting assistance to end his or her own life has the capacity to make”,

that decision. I listened carefully to what my noble friend Lady Hollins said about psychiatrists not necessarily being brought in. However, I should like to think that we can rely on the professionalism and training of our doctors and that if they were in any doubt at all, they would call in a psychiatrist to make this assessment to reach that very high level of satisfaction that the patient has the mental capacity.

The requirement to call in a psychiatrist if the doctor is concerned about the person’s mental capacity was included in the original Bill of the noble Lord, Lord Joffe, but is not in this Bill. As my noble and learned friend Lady Butler-Sloss said, subsection (2) of the proposed new clause points out that the person should not be,

“suffering from any condition, including … depression”,

which could impair his or her judgment. Recent medical evidence has revealed that the presence of depression in terminally ill patients is much higher than in other patients. In a report in the BMJ, Prevalence of Depression and Anxiety in Patients Requesting Physicians’ Aid in Dying, the authors investigated terminally ill patients in Oregon who requested aid in dying and found that more than 50% met the criteria for depression or the criteria for anxiety that they were depressed. Depression can leave a person with unchanged mental capacity; it can also radically change a person’s mental capacity. There was rather a good article in the Journal of Clinical Oncology entitled “Euthanasia and Depression: A Prospective Cohort Study Among Terminally Ill Cancer Patients”, which discovered that the risk of requesting euthanasia for patients with a depressed mood was 4.1 times higher than that for patients without a depressed mood.

This amendment would put the onus on the doctor assessing the mental capacity of a patient to bring in a psychiatrist if they were at all concerned about this condition. Proposed subsection (3) seeks to set out the criteria for the psychiatrist who is going to be involved. The 2005 mental capacity committee heard from Dr Geoffrey Lloyd of the Royal Free Hospital’s department of psychiatry that in more complicated cases only liaison psychiatrists have the expertise to assess a patient’s mental capacity correctly. The report said:

“There was a general consensus among our expert witnesses on one point—that the attending and consulting physicians who are envisaged as being effectively the ‘gatekeepers’ in regard to applications for assisted dying could not be expected to spot impairment of judgement in all cases”.

Proposed new subsection (4) asks for the psychiatrist also to be satisfied that the person making the request has the capacity to make the decision to ask for assistance with dying. Patients can be very good at deceiving even trained psychiatrists about their state of mind and can appear to be capable when they are not. The same often appears with people who are suffering from dementia. Psychiatrists may need to make another visit, maybe a month or so later, to make a proper assessment of their capacity. I can quite see that this sort of period can make the delay too long for many terminally ill patients. My answer must be that the most important thing is to get the decision right. I hope that this amendment will do just that.

[Lord Swinfen (Con)]

I support the noble Baroness, Lady Hollins, on her Amendment 71. Given the gravity of the decision to end one’s life, ensuring that a person requesting assisted death has the capacity to make this decision is of fundamental importance, yet the Assisted Dying Bill raises serious concerns about how decision-making capacity will be determined.

Furthermore, I think that the Bill is inaccurate from a legal standpoint with respect to the assessment of mental capacity. The Mental Capacity Act 2005 states at its outset that:

“A person must be assumed to have capacity unless it is established that he lacks capacity”.

Section 62 of the same Act makes clear that,

“nothing in this Act is to be taken to affect the law relating to murder or manslaughter or the operation of section 2 of the Suicide Act 1961”.

Yet Clause 12 of the Bill of the noble and learned Lord, Lord Falconer, states that,

“‘capacity’ shall be construed in accordance with the Mental Capacity Act 2005”.

The Mental Capacity Act for England and Wales has established the legal criteria to be met if a person is to be considered to lack capacity in relation to the matter in question. There is a requirement that,

“at the material time he is unable to make a decision for himself in relation to the matter because of an impairment of, or disturbance in, the functioning of, the brain or mind”.

Mental capacity must then be functionally assessed, as it is decision specific and time specific.

In the context of this Bill, the person must have the capacity to make the decision to ask for and, if offered, accept a medical intervention, the consequence of which is death. Given the criteria set out for decision-making capacity in the Mental Capacity Act, the person concerned would need to understand and balance knowledge of their existing medical condition and any potential treatments, and the likely benefits of further palliative care, and be able to communicate this choice, being fully aware that the consequence if the doctor agreed to carry out the procedure would be his death.

From April 2007, the Mental Capacity Act has provided the legal framework in England and Wales for substitute decision-making with respect to healthcare treatment when a person lacks the capacity to make relevant treatment decisions for himself. This can be helpful to people nearing the end of their lives. Lasting power of attorney for health and welfare allows decisions to be delegated to one or more attorneys of your own choice. You can also give your attorneys the power to refuse or agree to any medical treatment you may need to stay alive, if ever you are unable to make that decision. This is called an advance decision and is legally binding if the circumstances are the ones you specified. Any action taken must, under the Mental Capacity Act, respect valid LPAs and advance decisions to refuse treatment.
