Campaigners in Newcastle say the decision by a High Court judge to order a review into the decision making process by the NHS will delay a change that is already long overdue
Safe and Sustainable was ordered after the deaths of more than 20 babies at a hospital in Bristol in the late eighties and nineties.
It called for changes to the way children's heart surgery was provided. Creating specialist centres of excellence with more surgeons operating in once place carrying out a minimum of 400 operations a year.
Last year the Joint Committee of Primary Care Trusts (JCPCT), whose job it was to decide where those centres of excellence would be, reported back.
Newcastle's Freeman Hospital was chosen to be the centre for excellence for the North.
So why has that decision now been called into question by a High Court judge?
Mrs Justice Nicola Davies accepted pleas from campaigners in Leeds that the procedures used in the decision making were unfair. She also ruled that the panel involved did not measure the 'quality' of various hospitals.
The main problem is with the way the JCPCT scored each hospital.
Lawyers for the Save our Surgery campaign group argued it was unfair the scoring methods used when measuring each hospital against another were not fully disclosed before the decision was reached.
They said it would have taken only a minor change in the scoring to have a major impact on the result. With just one point standing between Leeds and Newcastle's Freeman on critical 'quality' scores the judge said basic fairness demanded full transparency of the methods used by the JCPCT.
Ivan Hollingsworth's son Seb is a heart patient at Newcastle's Freeman Hospital. Mr Hollingsworth has campaigned vigorously for the unit there to remain open.
He says today's decision is devastating for the families of heart children all over the country, delaying again changes that are vitally needed.
There will be a further hearing at the High Court on March 27 when the judge will decide whether to overturn the original decision, forcing it back to the drawing board.
