The parents of a 23-month-old boy who has been at the centre of a life-support treatment battle are set to mount another legal challenge.
Tom Evans, 21, and Kate James, 20, are preparing to ask Court of Appeal judges to allow Alfie Evans to continue to receive treatment.
Appeal court officials say a hearing has been listed for Monday.
The couple, who are from Liverpool, have already lost fights in the High Court, Court of Appeal, Supreme Court and European Court of Human Rights.
In February, Mr Justice Hayden ruled that doctors at Alder Hey Children's Hospital in Liverpool could stop treating Alfie against the wishes of his parents following hearings in the Family Division of the High Court in London and Liverpool.
On Wednesday he endorsed a detailed plan put forward by Alder Hey doctors for withdrawing life-support treatment - after considering a number of issues at a follow-up hearing.
The judge said detail of that plan could not be revealed because Alfie was entitled to privacy at the end of his life.
Legal advisers representing the couple say they will ask appeal court judges to overturn at least one decision made by Mr Justice Hayden on Wednesday.
Appeal court officials said an appeal court judge had decided that Alfie should continue to receive treatment pending Monday's Court of Appeal hearing.
Judges have heard that Alfie, born on May 9 2016, is in a "semi-vegetative state" and has a degenerative neurological condition doctors had not definitively diagnosed.
Specialists at Alder Hey said life-support treatment should stop and Mr Justice Hayden said he accepted medical evidence which showed that further treatment was futile.
Court of Appeal judges upheld his ruling.
Supreme Court justices and European Court of Human Rights judges have refused to intervene.
Alfie's parents have complained that "the state" is wrongly interfering with their parental choice.
They want to move Alfie to a hospital in Rome or Germany.
