Michael Lees from the campaign group Asbestos in Schools, will be amongst those attending a committee meeting today, to discuss the issue of asbestos.
Michael's wife Gina was a school teacher, who died from mesothelioma, the form of cancer developed from exposure to asbestos.
Speaking to Daybreak he said: "You are aware that asbestos exists, but you are certainly not aware of the dangers, and the fact that just the simple act of going to school, you can die of an industrial disease."
Municipal Mutual Insurance is one of four insurance firms involved in the asbestos legal action. In a statement it said:
Whilst the ruling does not reflect MMI's favoured outcome, we welcome the clarity this judgment brings as it enables MMI to determine the extent of its liabilities... It should be noted that MMI has continued to compensate local authority employers for mesothelioma claims, despite not being obliged to pay out claims until the outcome of the case was known.
Leslie Screach died in 2003 after being exposed to asbestos fibres. Today his daughter Ruth Durham said she still had mixed emotions:
I am delighted to hear of the court's decision which will now see justice done for my father and the other mesothelioma sufferers. I was determined to see this through with a positive outcome for all those who, like my dad, suffered so terribly because of someone else's negligence. I miss him every day and no sum of money will ever bring him back or make up for what he went through.
Lawyer Helen Ashton said today's ruling provided "clarity and comfort" for families of mesothelioma victims. She represented the lead claimant in the case:
As well as the people currently directly affected by asbestos related disease, this judgment means that the thousands of people who are yet to be given the devastating news that they have the deadly illness will at least know that their families can get access to justice and receive the financial security they need. But the sad fact is that many victims of mesothelioma who have been awaiting the outcome of this appeal may not have lived long enough to know if their families will now receive the compensation they deserve.
