Terminally Ill Adults (End of Life) Bill

Baroness Lawlor Excerpts

Friday 14th November 2025 Lords Chamber

[Baroness Butler-Sloss (CB)]

I have not the remotest idea. It is such an important point that I would have to go away and reflect. I am not commenting on ability or capacity; the point I am making to the Committee is about the difficulty of this for a doctor, or several doctors—probably GPs. The Royal College of Psychiatrists, of which I am an honorary fellow, has said firmly that it wants nothing whatever to do with the panel or with this, so doctors who are not psychiatrists will decide, with other people, whether somebody has or does not have capacity. That is what is currently in the Bill.

I warn your Lordships that this can be difficult, particularly when it involves depression. I had a friend, a solicitor, who suffered from depression. She said that she used to fall into a black pit and try to crawl up the sides, which were slippery. It was clear to me that, when she was in that depression, she certainly did not have the ability to make serious decisions. So I warn your Lordships about the potential problems of assessing capacity.

[Baroness Lawlor (Con)]

My Lords, I support the amendment in the name of the noble Baroness, Lady Finlay, to substitute “ability” for “capacity” in Clause 1(1)(a). As Clause 3 explains—we have already spoken about this at length—capacity is to be understood as defined in the Mental Capacity Act 2005. But, in my view, capacity so defined is the wrong measure to use to discern whether someone is in a position to make a proper judgment about ending their own life.

The Mental Capacity Act sets a very low threshold for having mental capacity. The Act requires—it could hardly do otherwise—that the person concerned must be able to understand the information relevant to a decision, but it dictates that this requirement should be understood in the laxest way, because Section 3(2) states:

“A person is not to be regarded as unable to understand the information relevant to a decision if he is able to understand an explanation of it given to him in a way that is appropriate to his circumstances (using simple language, visual aids or any other means)”.


We have heard from the noble Baroness, Lady Finlay, about the problems of information, facts, evidence and understanding that she has encountered in her very distinguished specialism. In effect, then, someone who can grasp only a diluted, simplified version of the information needed for a decision is still thought to have capacity to take it.

In Section 3(3) the Act adds that, although the person concerned may be able to retain the information, as per Section 3(1)(b):

“The fact that a person is able to retain the information relevant to a decision for a short period only does not prevent him from being regarded as able to make the decision”.


The Act therefore allows that someone who cannot retain information in the normal sense of the word “retain”, which means that something is kept, in this case in the memory, none the less has capacity.

Although the Act makes the threshold for mental capacity as low as it can, arguably that is good for the purpose of the Act, because very strong reasons are required before we take an individual’s power of agency over important decisions about the conduct of their life, which is the result of declaring that they lack capacity. If there are any grounds, however slight, we should accept that they have capacity.

But, in the case of the Bill, this position is reversed. We are dealing here with a decision that, in its gravity and irrevocable nature, is completely unlike most—or all—of those important decisions that the Mental Capacity Act was designed to regulate. Where the decision is to end one’s own life, what matters above all is that the agent is able to understand its meaning and consequences. It is not enough in this case that the information relevant to the decision is grasped in a simplified or pre-conceptual form, as the Mental Capacity Act definition would allow, nor that the information is retained only for a moment, then to be forgotten, as again is allowed by the Mental Capacity Act definition. The threshold for being allowed to take the decision must be much higher. Even though making it higher would take away the power of agency from more people than a lower threshold would, it is wholly justified when, as here, it concerns a decision that, if made, will entirely and irrevocably remove an individual’s power of agency.

I agree that “ability” lacks the precise legal definition— I am very grateful to the noble and learned Baroness, who was very candid about what that could mean—that “capacity” has. It is better to have an imprecise phrasing that points in the right direction than one that points the wrong way. Moreover, the phrasing of the amended clause indicates how we should understand ability. It is an ability to make the brave and difficult decision to end one’s own life. Clearly, an ability commensurate with the gravity of that difficult and brave decision is an appropriate way. I support the aim, and, indeed, the wording, of the noble Baroness’s amendment, because of the gravity of the decision that is being taken.

--- Later in debate ---

[Lord Sandhurst (Con)]

I wanted to make it plain because some people listening to the noble and learned Lord might have thought I had not said that.

[Baroness Lawlor (Con)]

Before the noble and learned Lord finishes, can he clarify for the Committee that a person who can grasp only a diluted amount of information, or who cannot retain the information in any real sense that would be intelligible to us, can be deemed to have capacity for the purposes of the Mental Capacity Act, but for this Bill, which is designed to give people agency and allow an individual as much choice as possible to choose treatment or have agency over medical and palliative care decisions and so on, an entirely different threshold should, quite rightly, be expected for such a serious measure as this?

[Lord Falconer of Thoroton (Lab)]

I respect the noble Baroness for repeating her speech. Section 3 of the Mental Capacity Act says that if a person is unable to

“understand the information relevant to the decision … to retain that information … to use or weigh that information ... or … to communicate his decision”,

then they do not have capacity. I am content that that should be the approach under the Bill.
