So judges without medical degrees can declare people brain-dead?
Some more background:
At the end of a final hearing on 13 June, the judge ruled that Archie had died on the day of his MRI scan on 31 May and his life support treatment could stop.
Doctors treating Archie told the High Court that it was “highly likely” he was “brain-stem dead” following scan results and asked the court to consider ordering that his life support should be stopped.
During the final hearing, specialists said tests had shown no “discernible” brain activity and that parts of his brain were showing “significant areas of tissue necrosis”.
Lawyers representing the trust had asked Mrs Justice Arbuthnot to decide what next step was in Archie’s best interests.
Following the ruling on 13 June, Alistair Chesser, chief medical officer at Barts Health NHS Trust, said their “thoughts and sympathies” were with Archie’s family.
