Barts Health NHS Trust v Dance, Battersbee & Battersbee  WFC 80 (on the Judiciary UK website).
The Archie Battersbee decisions, leading up to the current decision of the Family Division of the High Court (UK), have been the subject of considerable media and social media attention. Part of the earlier debate touched on the issue of whether Archie, aged 12 years, was already dead (brain stem death) such that a best interests decision was no longer appropriate. However the present Court said that ascertaining death requires the application of clear clinical guidelines. Where they are not met, brain stem death cannot be identified with the certainty that such a conclusion requires.
A best interests decision was therefore required in the context of his catastrophic hypoxic ischaemic brain injury and coma (Glasgow 3/15) of three months duration. There was a bleak but unanimous professional consensus.
Archie’s mother had pursued a media campaign in what she perceived to be a fight against the Hospital Trust. The judge said at :
Whilst I entirely understand why Archie’s mother would wish to cling on to these thoughts, I am required to confront the compelling medical reality that Archie no longer has the agency to fight. His bodily autonomy has been devolved to the clinical machinery, medication, and nursing care.
The Court, applying Aintree University Hospital NHS Trust v James  UKSC 67, concluded at :
This court has to ask itself whether continuation of ventilation in this case is in Archie’s best interests. It is with the most profound regret, but on the most compelling of evidence, that I am driven to conclude that it is not. Accordingly, the Court cannot authorise or declare lawful the continuation of this present treatment. It is obvious from the detail of the treatment that I have set out above that it is intrusive, burdensome and intensive. If there were even a possibility that it could achieve some improvement to Archie’s condition, it might be both proportionate and purposeful. Where, as here, the treatment is futile, it compromises Archie’s dignity, deprives him of his autonomy, and becomes wholly inimical to his welfare. It serves only to protract his death, whilst being unable to prolong his life.
