"The World Medical Association, to which the South African Medical Association (SAMA) belongs, adopted the Declaration of Venice on Terminal Illness in 1983. In this declaration doctors are encouraged to recognise the right of patients to make advance directives, such as living wills, to describe their wishes in the event that they are unable to do so.
Sama's guidelines for medical practitioners on living wills says doctors who have "conscientious objections" to withholding treatment should advise you or your family of their views and offer to step aside and transfer your care to another practitioner who will abide by the instructions in your living will."
