The parents of a 12-year-old boy at the centre of a life-support treatment dispute are waiting for a High Court hearing next week after they won an appeal for their son's case to be reconsidered.

Mrs Justice Arbuthnot ruled on June 13 that doctors could lawfully stop providing treatment to Archie Battersbee, after considering evidence at a trial in the Family Division of the High Court in London.

However, she said there was a "compelling reason" why appeal judges should consider the case.

Edward Devereux QC, who is leading Archie's parents' legal team, argued evidence had not shown "beyond reasonable doubt" that Archie was dead.

He said the decision had been made on a balance of probabilities - and argued a decision of such "gravity" should have been made on a "beyond reasonable doubt" basis.

Mrs Justice Arbuthnot decided that appeal judges should consider that standard of proof issue.

Three appeal judges analysed the case at a Court of Appeal hearing in London on June 29.

Lawyers representing Archie's parents, Hollie Dance and Paul Battersbee, of Southend, had argued that Mrs Justice Arbuthnot made errors and said the case should be sent back to the High Court and reconsidered.

Sir Geoffrey Vos, the Master of the Rolls; Sir Andrew McFarlane, the president of the Family Division of the High Court and most senior family court judge in England and Wales; and Lady Justice King ruled another High Court hearing will take place focusing on Archie's best interests.

This hearing is set to take place on Monday (July 11).

Doctors treating Archie at the Royal London Hospital in Whitechapel, east London, told Mrs Justice Arbuthnot in the first hearing how they think Archie is "brain-stem dead".

They said treatment should end and Archie should be disconnected from a ventilator.

Archie's parents say his heart is still beating and want treatment to continue.

The 12-year-old suffered brain damage in an incident at home in April.

Ms Dance has told how she found her son unconscious on April 7 and thinks he might have been taking part in an online challenge.

He has not regained consciousness.
