According to the search results, Andy Casey was a 20-year-old man who suffered a serious brain injury after being punched from behind in a pub garden fight in July 2023. He had been in a coma ever since and was on life support at St Georges Hospital in Tooting. His relatives had lost their High Court fight for his treatment to be continued, and specialists had declared that his brain-stem function had died, meaning that he was brain-stem dead and therefore dead. Despite his sisters belief that he was not brain-stem dead, the court ruled that it was lawful for the hospital to cease artificial ventilation and care that Andy was receiving. His family was refused permission to appeal the decision to take him off life support.
