Assisted Dying Bill [HL]

Perhaps the noble and learned Baroness can help me with that question of capacity. There are some elements, such as depression, which come and go at various levels. A depressed person may sometimes have capacity and sometimes not. An alcoholic may not have capacity but, on the other hand, he may have it when he sobers up for a while. The same applies to a drug addict, who may or may not have capacity according to how much he has taken. I find that rather difficult to judge against the more permanent and unchanging stages of capacity and incapacity; for example, in a patient with Down’s syndrome, whose capacity would be limited but probably more or less unchanging, or somebody in the later stages of Parkinson’s disease, where that mental capacity was beginning to go but could only get worse. I am a little puzzled as to how one would make the decisions between those varying states.
