In the final part of the sad saga regarding the withdrawal of artificial nutrition and hydration from a brain injured man in MCS, the Court of Appeal have now made it clear in Director of Legal Aid Casework & Ors v Briggs [2017] EWCA Civ 1169 that seeking an order under section 21A of the MCA is not a legitimate way of seeking a best interests declaration in respect of serious medical treatment. King LJ said at [110]:
“…in my judgment s.21A goes to a consideration of whether the detention or deprivation of liberty is itself in P’s best interests and, whilst the surrounding circumstances are part of the picture, the question is not whether the circumstances, including the medical treatment P requires, (which amount to a deprivation of liberty), are in the best interests of P, but whether it is in the best interests of P to be a detained person.”
