Attempted CPR and possible legal prosecution
I believe the type of prosecution mentioned by Richard Venn in his rapid response (this series) of 16 January is very unlikely, however desirable it might seem.
I think the most likely prosecution, will [if it happens] be for attempted CPR after a suitably-empowered welfare attorney has expressed a decision that attempted CPR would not be in the patient's best interests. The wording of the Mental Capacity Act, in section 6(7), seems quite clear, and I would point at the word 'while': the relevant wording is 'while a decision as respects any relevant issue is sought from the court'.
And, I consider that the most likely person to be prosecuted for such an 'assault', is a 999 paramedic.
