Campaigners in Leeds have won a High Court challenge over proposed changes to children's heart surgery services in England.
Save Our Surgery (SOS), which is trying to stop the closure of the heart unit at Leeds General Infirmary, argued the consultation process leading up to the changes was "unfair and procedurally flawed".
The original decision meant surgery would continue at Southampton Hospital's heart unit.
Today Mrs Justice Nicola Davies, sitting at London's High Court, ruled that the challenge to that decision must succeed - but what the ruling means for the future will be decided at a later date.
This judgment is in itself a victory for the people who fought to keep children's heart surgery services in Yorkshire, and to challenge what they knew to be a flawed and unjust process."
Campaign group Save Our Surgery (SOS), which represents a large number of residents in the Leeds area, wants a rerun of the consultation on where specialist heart units should be based.
Leeds missed out during the consultation - which went in Southampton's favour.
Judge Mrs Justice Nicola Davies, sitting in London, said she would use "every endeavour" to get the final judgment out today.
The judge is being asked to declare that the consultation process which led to the changes, including proposals to close the heart unit at Leeds General Infirmary, was unfair and "procedurally flawed".
