Relatives of a 20-year-old roofer who suffered a brain injury after becoming involved in a fight in a pub garden say they aim to appeal after failing to persuade a High Court judge that life-support treatment should continue.
Specialists say Mr Casey’s brain stem function has died and he is therefore dead.
The judge, who oversaw a private trial in the Family Division of the High Court in London on Friday, said he agrees.
Hospital trust bosses responsible for Mr Casey’s care had asked the judge to rule that treatment can lawfully end, but his relatives want it to continue and say they have seen movement and signs of life.
Mr Casey’s sister Christine, 27, told the judge she does not believe he is brain-stem dead.
After the ruling, she said she is “so angry” and that relatives aim to appeal.
Miss Casey said the judge had looked at video footage showing Mr Casey moving.
“He reacts to pain,” she said. “I showed the judge so many videos.
“How can someone who reacts to pain be dead?
“We are looking at an appeal.”
A lawyer representing St George’s University Hospitals NHS Foundation Trust, which is based in Tooting, south London, and has responsibility for Mr Casey’s treatment, asked the judge to rule it would be lawful to cease artificial ventilation and care.
Barrister Abid Mahmood said brain stem testing by two specialists had shown Mr Casey is dead.
Mr Mahmood told the judge in a written case outline that Mr Casey had been involved in a fight in a pub garden on July 9 and was “punched to the head” and “fell to the ground”.
He said specialists had diagnosed death on July 16.
The judge heard Mr Casey had remained on a ventilator since being injured.
In a written ruling, Mr Justice MacDonald said: “Whilst I understand fully the conclusions that the family and friends of Mr Casey have, in their sorrow, drawn from his movements and apparent responses to the ventilator, having regard to the totality of evidence before the court, I am also satisfied that what the family are seeing are in fact well-recognised base reflexes that can survive brain stem death.
“Cruelly, the flattering voice of hope convinces those that love Mr Casey that these are signs that Mr Casey is not dead.
“With regret, I am satisfied that the brain stem testing undertaken… demonstrate(s) that he is.”
Mr Justice MacDonald said he had concluded, with “very great sadness”, that Mr Casey “died on 16 July 2023 at 11.51pm”.
He added: “I understand that this will come as a bitter disappointment to Mr Casey’s family and friends.
“The now blurred boundary between life and death can be delineated by reference to philosophy, to ethics or to the cardinal tenets of the world’s great religions.
“But the task of this court is to consider whether Mr Casey has crossed over that boundary for the purposes of the law.”
He said he is satisfied, having regard to brain stem testing undertaken in accordance with a code of practice, that Mr Casey had died.
The judge went on: “I recognise that this is a tragedy for his family and friends and whilst I am certain that it will offer little comfort, they have my profound sympathy.”
