The doctor is also excused from conferring with the patient in circumstances of necessity, as for example where the patient requires treatment urgently but is unconscious or otherwise unable to make a decision." In addition, the Court specifically states that the duty is to inform of any material risk.

The question therefore is what a material risk is and more importantly how...
