A United Kingdom judge has refused to overturn a previous judge's decision that it is in baby Alfie Evans' "best interest" to discontinue ventilation, which will likely cause his death.
Last month, Mr Justice Hayden had ruled that it was in Alfie's best interests for his treatment to be withdrawn.
The parents of a 23-month-old boy at the centre of a life-support treatment battle have lost their latest legal battle to have their child treated overseas.
He sought to overturn Mr Justice Hayden's decision last week that Alfie's parents may not remove him from Alder Hey hospital.
He then alleged the hospital called the police to prevent him removing his son, with officers allegedly telling him he would be "arrested for assault" if he attempted to remove Alfie.
Alder Hey said noise from hundreds of protesters supporting the 23-month-old, including the sounding of vehicle horns, was affecting its patients and staff.
The toddler's family have said they are accompanied by their own doctors, have removed duty of care from the hospital and placed it with their air ambulance, and have a jet ready to take the child to Italy.
In his ruling today, Lord Justice Moylan repeated the arguments made recently by Lord Justice Hayden about the baby's care.
"The bad reality was that nearly the entirety of Alfie's brain has been eroded, leaving only water and cerebral spinal fluid", Moylan said, reading from Hayden's previous decision, according to The Sun. Moylan, however, disagreed on the basis that the court had already decided that it was in Alfie's best interest to remain at Alder Hey hospital.
The justice stated that the parental rights of Tom and Kate over Alife "do not take precedence".
The hearing resumed on 1 February at the High Court in Liverpool, in which lawyers acting for the hospital claimed further treatment for Alfie was futile and inhumane. "It is precisely because of this judicial determination that Aflie has been kept in Alder Hey Hospital", he said.
The Court of Appeal, the Supreme Court and the European Court of Human Rights upheld that decision. Diamond indicated that he would make a direct appeal to the Supreme Court by 4 p.m. local time on Tuesday.
Alfie Evans, born May 9, 2016, is lying critically ill in Alder Hey Children's NHS Foundation in Liverpool.
Doctors said he had a degenerative neurological condition which they have not been able to identify definitively.
