So ultimately, a court will decide whose beliefs trump anothers
Only in the very rare circumstances where a persons wishes are completely unknown and there is conflict around what their wishes may or may not be.
Additionally not treating someone who doesnt want to be treated is entirely consistent with medical ethics, to force treatment on that person would be to "harm" them mentally and/or emotionally, as well as not respecting their autonomy or dignity.
The Edinburgh Oath is as follows:
I declare that I will practise my profession to the best of my knowledge and ability, in good conscience and with integrity.
In my practice the care of my patients will be my first consideration.
I will strive to prevent and treat disease, improve quality of life, provide support in times of suffering.
I will respect the autonomy, confidences and
dignity of all my patients in their living and in their dying.
I will promote the health and welfare of the community.
I will treat with respect my colleagues and all who contribute to the well being of my patients.
I will constantly seek to gain in knowledge and understanding, and to pass on the art and science of medicine to others, as my teachers have done before me.
I will treat all patients equally and without prejudice.
I will not breach these obligations, or abuse the trust placed in me, either under threat or for personal gain.
I make this declaration solemnly, freely, and upon my honour.
