Mental health – Persons who lack capacity. A 17 year old girl, P, took an overdose and refused life saving treatment when presented at a hospital run by the defendant NHS Trust. The Trust came to court seeking various declarations that it was lawful and in P's best interests for the medical practitioners having responsibility for her care and treatment to treat her for the overdose notwithstanding the fact that she was refusing treatment. The Family Division held that it was lawful to make such a declaration in order to save P's life.
