Parichehr Salasel believed that where there was life, there was hope. Two doctors at Toronto’s Sunnybrook Health Sciences Centre disagreed, saying that it is in the best interests of her husband, Hassan Rasouli, who is in a permanent vegetative state, to be taken off life support and provided with palliative care until his death. The seven-month medical conflict over Mr. Rasouli’s fate ended on Wednesday when Ontario’s top court took Ms. Salasel’s side in a ruling that is expected to reignite for Canadians the emotional issue of how to handle end-of-life decisions and whether extraordinary medical interventions save lives or merely prolong dying.
