Summerland campaigners have been granted leave to appeal a decision not to order fresh inquests into the deaths of the 50 adults and children who lost their lives in the blaze.
And it has emerged that the appeal hearing could be live streamed when it takes place next year, given the public interest in the case.
In July a call to reopen an inquest into the 1973 Summerland fire tragedy was rejected by the high court.
First Deemster Andrew Corlett ruled that the Attorney General had not erred in law last year when he directed the Coroner of Inquests not to hold new inquests.
Jackie Hallam, of the Justice for Summerland campaign group, has now been granted leave to appeal that ruling.
At a directions hearing Judge of Appeal Anthony Cross KC said the principles underlying the decision to order a further inquest had never been argued and adjudicated in the appeal court before.
He said: ‘It’s quite clear in my view that it’s in the public interest for that to occur.’
Advocate for the campaign group, Steven Coren, thanked the court for giving permission to appeal on all nine grounds submitted.
The Judge of Appeal said the earliest the appeal could take place is on the week commencing February 15 next year.
He said he would be sitting with Honour Judge Alexia Durran, current Chief Coroner for England and Wales, and Sir William Bailhache KC, former Bailiff of Jersey.
Judge of Appeal Cross said: ‘I want the public to be able to understand that the group dealing with this appeal have the experience to deal with the complex issues that arise in it.’
He said he was well aware of the legitimate public interest in the case and he was keen for the public to be able to observe the proceedings as easily as possible.
Some work was underway about broadcasting Manx proceedings, he revealed.
He said all options, including sound and vision, or sound alone, would be considered if thought to be in the public interest for proceedings to be broadcast.
The appeal hearing is being estimated to run for 1.5 to two days.
Fifty people died including 11 children died in the blaze at the Summerland leisure centre on August 2 1973. Eighty people were seriously injured.
The fire was the subject of a lengthy judge-led public inquiry which reported in 1974 and which highlighted errors in planning, design and staff training as well as failings on the night of the blaze including locked or blocked fire exits.
A short inquest held on August 27 1974 returned unanimous verdicts of death by misadventure.
The Justice for Summerland group called for a fresh inquest in the wake of a Dublin jury ruling in April 2024 that 48 people were ‘unlawfully killed’ in the Stardust nightclub fire in 1981, overturning the original verdict of arson.
Campaigner Mrs Hallam was just 13 when she got caught up in the fire at the Summerland entertainment complex on August 2, 1973. Her mum and best friend were among those who died.
