Terminally Ill Adults (End of Life) Bill

Debate between Lord McCrea of Magherafelt and Cookstown and Lord Scriven

Committee stage
Friday 14th November 2025 Lords Chamber

[Lord McCrea of Magherafelt and Cookstown (DUP)]

My Lords, earlier on in the debate, there was a discussion concerning members of the committee, on who was or was not called, or who was denied the right to be called to it. I suggest that the straitjacket of the time this House allocated probably did not allow the relevant committee the appropriate time to call everyone that it thought was appropriate. It ought to have been given more time, but it seems that it had to be rushed.

Concerning the Mental Capacity Act, Margaret Flynn, chair of the National Mental Capacity Forum, said it was designed to protect us

“when others start to make decisions about our lives … Assisted dying was not on the table during the Law Commission’s consultation which resulted in the MCA”.

Therefore, the suitability of the Mental Capacity Act 2005 as a test for a decision to end one’s life is a major source of debate. I believe the many experts and professionals arguing that it is insufficient for this specific irreversible decision.

The MCA was not designed for assisted dying. It was created to safeguard people who lack capacity in decisions about their care, treatment or finances. Assisted dying was not on the table during the Law Commission’s consultation. The Royal College of Physicians, as the noble Lord said a moment ago, said that applying the MCA to the decision to end one’s life is an entirely novel test in uncharted territory with no experience or precedent. It is a very low threshold. The Royal College of Physicians argues that assessing a person’s mental capacity to decide to end their life is an entirely different and more complex determination, requiring a higher level of understanding than assessing capacity for treatment decisions.

[Lord Scriven (LD)]

I have listened very carefully to the noble Lord and a number of others. I am still struggling to understand what the higher test of ability would be, over and above the Mental Capacity Act. Will the noble Lord let the House know what that higher test is that people would have to go through on ability rather than capacity?

[Lord McCrea of Magherafelt and Cookstown (DUP)]

The noble Lord knows that I am not a proposer of the change of words. I am dealing with capacity. Therefore, I am also dealing with the fact that professionals within the field have stated that to use the Mental Capacity Act for a decision to end one’s life is an entirely novel test and uncharted territory for which there is no experience or precedent. That is not my statement; that is the statement of professionals within the field. They say also that to decide to use it for the decision to end one’s life is an entirely different and more complex determination requiring a higher level of understanding than assessing capacity for treating decisions.

Capacity can fluctuate in terminally ill patients due to physical fatigue, illness, medication or delirium, making the irreversibility of the decision risky under this framework. Therefore, I ask this Committee to think carefully in trying to base its whole argument on this being good legislation because mental capacity is the deciding factor.
