Terminally Ill Adults (End of Life) Bill

Debate between Lord Deben and Lord McCrea of Magherafelt and Cookstown

Committee stage
Friday 14th November 2025 Lords Chamber

[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.

[Lord Deben (Con)]

I wonder whether I can help the Committee. I think we may be discussing two rather different things, so I suggest that we decide which of them to discuss.

There is the discussion as to whether the word “capacity” really includes all the things that people are pressing for when they use the word “ability”. That is the point that the noble Lord, Lord Pannick, was clearly making when he expressed the nature of the word “capacity” as used in law. It is perfectly understandable that people would want to say, “Here is a word that we use. It’s a word which is defined and has been defined over a long period of time. Therefore, it’s stood the test of time”. I understand the noble Baroness, Lady Andrews, who rightly mentioned the amount of time that had been taken to deal with that.
