Comment and discussion
The asbestos expert interview
An interview with Bob Clark, [retired] Consulting Engineer, specialising in asbestos claims
[March 2009].
How many reports have you written and over how many years?
I was a HSE/Factory Inspector from 1975 – 1990. Thereafter in private practice, I have written on average about 120 reports a year until 2008. Of the 120, about 10 a year could not go forward. Of course, by time I am instructed, solicitors have already sifted out the more obviously difficult claims that cannot go forward including those where the employer has closed down and an insurer cannot be found.
Did HM Government do enough?
Merewether got it right in 1930 as to heavy dust exposure, for example, in asbestos factories where crude asbestos was processed and converted into asbestos goods. Thereafter, I take 1965 as the definitive "trigger" date when industry and other interested parties ought to have known about smaller amounts of dust causing mesothelioma. As a judge reportedly said, although this may be apocryphal, “The Sunday Times’ article, "Scientists track down killer dust", was read at directors’ breakfast tables.” It is clear that, during the 1940s and 1950s, full disclosure of the hazardous nature of asbestos was deliberately withheld from Government by the asbestos industry and that the asbestos industry was lobbying hard in their own financial interests. The net result was that attempts to introduce new legislative controls were held back. For example, the introduction of the revised Shipbuilding Regulations was held back from early 1950s until March 1961.

Do you believe in the "one fibre" theory?
It seems to me that some individuals are more susceptible than others and develop mesothelioma after sustaining seemingly very low exposures to asbestos fibres. I can recall preparing a report in connection with a claim that concerned the domestic exposure of two boys who both contracted mesothelioma as a result of inhaling asbestos fibres that originated from their father's contaminated woolly jumper that he wore at work. Conversely, I find it astonishing that a few laggers, who must have sustained massive asbestos exposures over years, do not contract mesothelioma. There is no doubt that the risk of developing mesothelioma increases as the inhaled dose increases but why some individuals appear to be at a greater risk is a matter for the medical experts to consider.
Measurement of dust in the workplace has been very difficult and techniques developed slowly over the years. Until the membrane filter method was universally adopted in the 1960s, the UK and the USA used different techniques and adopted hygiene standards that could not be readily compared.
Do you blame HM Governments for not doing enough to save lives?
The blame lies squarely with the asbestos industry who failed to provide proper and full information to the Government. We all learnt a great deal from the T&N documents which emerged into the public domain following the Chase-Manhattan litigation in the USA. But even now, as I understand it, because of the vast amount of documents in the T & N archives, there has still not been a full examination of all the documents. Before this disclosure, documents, which had been signed by senior executives, were routinely served stating there were no relevant documents to be disclosed. But, when their archive was searched by the US lawyers, this proved to be manifestly untrue. I recall a legal executive having to try to explain this situation to the Court and saying in effect "what can I say" and having to admit that there were no excuses for failing to provide this information to the Claimants’ lawyers and the Court.
It should be remembered that the Government found itself in a paradoxical position with HMFI and HSE advocating the introduction of strict control measures concerning the use of asbestos-based materials and a ban on the use of crocidolite-based materials with a view to reducing risk to health while other Government departments were still insisting that asbestos should be used for fire prevention purposes in new buildings. Whilst with hindsight, it appears that the Government moved too slowly, whether or not there is ultimate culpability still needs to be fully investigated.
What is your view of the Sicily prosecutions and directors of Eternit being jailed?
Ultimately, even those in the asbestos industry will get their comeuppance. It is reported that, in the past, senior executives in the asbestos industry have developed and died from mesothelioma as a result of their occupational exposures to asbestos fibres.

The expert counsel interview
Roger Hiorns, 9 Gough Square chambers, London (2 2 2011)

From your experience when representing asbestos claimants what would you consider to be the thorny issues today?
The thorny issues of the day appear to be: firstly, what dose of exposure to asbestos is required to make a "material increase in the risk" of developing mesothelioma?; secondly, what does a claimant have to prove to satisfy a court that his lung cancer was caused by asbestos exposure?; and, thirdly, which insurer should pay an asbestos claim. Everyone seems to agree that the decision by the Court of Appeal in the "trigger issue" litigation left the law in a very unsatisfactory state.
What are your views on low dose claims before 1965?
Low dose claims before 1965 are fraught with difficulty unless there was a statutory duty which applied. Common law duties before 1965 will not assist a claimant in a low dose claim because employers would not be taken to have foreseen injury from low dose exposure. Unfortunately, most low dose claims before 1965 will not succeed.
Do you consider that the Mesothelioma Fast Track proceedure has been a success and do you believe it could be improved.
Everyone involved in asbestos litigation agrees that the mesothelioma fast track scheme has been an unparalleled success. The vast majority of mesothelioma victims now obtain compensation in their lifetime and this gives justice a good name. The only criticism there might be of the present system is that Masters could and should impose even tighter timescales on defendants in respect of disclosure of documents and service of witness statements.

A brief chronology of the Porton Down litigation -"volunteers" and chemical warfare agent experiments 1940s - 1980s

"If we tell them that the experiments should be lethal there would inevitably be a sharp fall off in numbers, and probably a degree of embarrassing publicity. On the other hand, if no more warning of the danger is given than at present, we may be quite rightly accused of deliberate misinterpretation in the future".

2004 [5th May] Ronald Maddison inquest commences in Trowbridge, Wiltshire before a jury.
http://www.guardian.co.uk/uk/2004/may/05/military
2004. During the inquest a 1953 letter from the Treasury Solicitor to Ministry of Supply [forerunner of MoD] is disclosed stating: ‘…The sentence ‘Tests are carefully planned to avoid the slightest chance of danger’ has proved misleading. Indeed it is difficult to see how it was ever possible to say truthfully that tests with lethal gases did not contain ‘the slightest chance of danger’….”. A second letter 15/8/1953 states that Section 10 does not apply to the Maddison experiment. “..When the case was referred to me previously I did consider the relevance of Section 10 of the Crown Proceedings Act 1947 but I came to the conclusion that it had no application. On the information before me I am still of that opinion…”
2004. Maddison inquest told about secret and officially denied MI6 LSD experiments at Porton Down in 1950s.
2004 [1.9] Professor Sir Ian Kennedy gives evidence at inquest. [Extracts from the Court transcript]: Kennedy – "We are not in the realm of holy writ, as you are trying to point out here. I doubt there is much in the literature on that, but I would say, yes, there may have been some then who would argue the point. I think the argument was bad then and I think the argument remains bad now. That is not to say there is no room for legitimate disagreement...the uncertainties were so great, that before proceeding to further research they should have been appropriately tested, analysed, with a view to controlling them, otherwise one is in the territory of an uncontrollable danger, and ethically, one should not be in that territory in terms of exposing volunteers to it. It is wrong to do so…"
2004 Veterans Agency (“War Pension”) appeal allowed for Michael Paynter and award for General Malaise (Chronic Fatigue Syndrome) and eczema. Michael Paynter had attended London Smog experiments at Porton Down. Archive document: November 1954. "14th meeting of the ACSRTD (Biology Committee) minutes – (b) Smog research. THE CHAIRMAN considered it refreshing that the committee could turn to a purely civilian problem…asked Professor Christie then to sum up the position as Chairman of the Medical Research Council’s Committee on smog. MR PATTLE said that the work being undertaken at Porton at the request of the Medical Research Council…”.

Porton Down Veterans
The Parliamentary Under-Secretary of State for Defence (Derek Twigg): The Ministry of Defence has for some months been in discussions with solicitors representing a group of Porton Down veterans regarding compensation claims arising out of their participation in the programme of trials undertaken at the Chemical Defence Establishment during the cold war. I am pleased to report that an amicable settlement has now been reached with respect to these claims. This settlement is without admission of liability by the Ministry of Defence and involves the payment of a global sum of £3 million in full and final settlement of all claims made by the group.
The Government have in the past made clear the debt owed by the nation to those who took part in the trials at Porton Down designed to ensure that the United Kingdom had the defensive and deterrent capabilities to counter the real and horrific threat that chemical weapons would be used against our armed forces or civilian population, as they had against others; the security of the country rested on these trials and the contribution of those who took part in them.
The trials were in many cases conducted under considerable pressures of time as new threats emerged. The Government accept that there were aspects of the trials where there may have been shortcomings and where, in particular, the life or health of participants may have been put at risk. The Government sincerely apologise to those who may have been affected.
