Cases

NHS North Central London ICB v PC et al [2024] EWCOP 31

The case concerned PC, a 31 year old woman, who suffered a cardiorespiratory arrest and collapsed at home.  A lack of cardiac output for about 30 minutes led to her brain being deprived of oxygen. She was left in what has been assessed as a Prolonged Disorder of Consciousness (‘PDOC’). The ICB made its application to the Court of Protection on 2 February 2024, seeking determinations under the Mental Capacity Act 2005 (‘MCA 2005’), including a declaration that it is not lawful, and not in PC’s best interests, to continue to receive the life-sustaining clinically assisted nutrition and hydration (‘CANH’) and that it would be in her best interests to refuse to consent to the continuation of CANH and other life-saving treatment.

Lilian represented PC’s mother, MC who was the third respondent in the proceedings. MC’s position was clear that she did not wish for CANH to be discontinued. Mr Justice Cusworth decided that, factoring the medical evidence  of PC’s condition which suggested that PC may had been in pain,  it was  not in PC’s best interests to continue to administer to her life-sustaining medical treatment in the form of CANH but rather that, it was in her best interests to begin to implement for her a palliative care regime the consequence of which (but not the aim) will be the end of her life.

In Re PC [2024] EWCA Civ 895

Lilian assisted MC in bringing an application to the Court of Appeal  to appeal the decision of Cusworth J in NHS North Central London ICB v PC et al [2024] EWCOP 31 on the basis of four grounds. In this case, counsel for MC suggested that the time might have come to revisit the established principles relating to life-sustaining treatment  laid down in Aintree Hospital NHS Trust v James [2013] UKSC 67 (“Aintree”).  

The Court of Appeal made it clear that Aintree remains the lodestar which guides the courts when considering these anxious cases and it that the sanctity of life is not absolute and that life sustaining treatment can nevertheless be withdrawn where it is not in the best interests of the patient. The courts have been most reluctant to lay down general principles which might guide the decision. The Court of Appeal  refused permission to appeal the decision.
