Capacity already plays a key role in end-of-life decision-making. People with capacity can refuse treatment, even if that is likely to result in their death.
The Mental Capacity Act (2005) means there is a legal framework that exists to support doctors to assess capacity.
If a doctor doubted a person’s capacity they would have to refer them to another professional, such as a psychiatrist.
The Royal College of Psychiatrists have a neutral stance on assisted dying.
