The daughter of Holby City actor John Michie might not have been saved had she received earlier medical help, the jury in the trial of her boyfriend has been told.
Ceon Broughton is accused at Winchester Crown Court of being responsible for the death of Louella Fletcher-Michie.
The 24-year-old yoga and dance teacher died while at Bestival, after she took a class A party drug 2-CP at on September 10, 2017, an hour before her 25th birthday.
Broughton, of Enfield, north London, denies manslaughter by gross negligence and supplying the drug.
The prosecution claims the 30-year-old defendant failed to take reasonable action to get medical help for Miss Fletcher-Michie.
The court has heard Miss Fletcher-Michie is understood to be the first person to have died after taking the drug.
Giving his closing speech, Broughton’s barrister Stephen Kamlish QC told the jury a lack of medical information about the effects of the drug meant it was “impossible” to tell whether any action taken by the defendant could have prevented her death.
He added the toxicology report was inconclusive about the amount of the drug Miss Fletcher-Michie had taken.
Mr Kamlish said the prosecution expert, Professor Charles Deakin, a consultant in cardiac anaesthesia and intensive care, had changed his opinion on the chances of survival.
He said Prof Deakin first of all gave a cut-off point that she could have survived after 9.10pm.
Mr Kamlish said the expert had changed this after a request for clarity from police and said she had, on the balance of probabilities, a 90% chance of survival with medical intervention after taking the drug.
He said: “There is a possibility that, even Professor Deakin himself acknowledged, that she might have taken so much that she could not have been saved while it was in her system, which means Ceon cannot be held to lame, however bad you find his behaviour.
“Why is someone being prosecuted for the death of someone who may never have survived?”
Mr Kamlish added: “No-one says he intended to cause her harm, they were going to have a good time, it was her birthday, she chose to take that drug.
“Something was different that day, she had never reacted that way before, you can’t be sure, like Professor Deakin can’t be sure, that she hadn’t taken too much.”
He added: “He (Ceon) didn’t want to leave her alone in the forest, he didn’t think she was going to die, he didn’t want to leave someone alone having a bad trip, you are not going to leave them alone in the forest until you think there is a risk of them dying.”
Mr Kamlish concluded: “To criminalise him for this would not be just.”
The trial continues.
