“Subject to the following provisions, “relevant employer”, in relation to a person disabled by a disease to which this Act applies, means any person- (a) by whom the disabled person was employed in a prescribed occupation at any time during the period during which he was developing the disease, and (b) against whom he might have or might have had a claim for damages in respect of the disablement.”
“A person is not a relevant employer in relation to a person disabled by a disease to which this Act applies if the disabled person has had no period of employment with him which is a qualifying period of employment.”
“mesothelioma is different in that it is not a cumulative condition where increasing damage is done with each exposure. It is a malignant condition in which the person exposed faces a “stochastic” risk that he may contract the cancer many years later. In the meantime he has no illness or disease and therefore no cause of action against his employer ( Rothwell v Chemical & Insulating Co.[2007] UKHL 39 ;[2008] 1 AC 281 ). In the cumulative conditions steady and repeated damage to lung tissue, however slight, is done on each exposure. The cause of action accrues as soon as “ more than minimal ” damage is done though that may be many years before symptoms appear and he has knowledge of his disease ( Cartledge v E Jopling & Sons Ltd[1963] AC 758 ).”
“7…[mesothelioma] is a condition which may be latent for many years, usually for 30-40 years or more; development of the condition may take as short a period as 10 years; but it is thought that is the period which elapses between the mutation of the first cell and the manifestation of symptoms of the condition. It is invariably fatal, and death usually occurs within one to two years of the condition being diagnosed...the greater the quantity of dust and fibre inhaled, the greater the risk. But the condition may be caused by a single fibre, or a few fibres, or many fibres…”
“The changes that we are making to the 1979 Act will incorporate in legislation a more practical version of the relevant employer condition than officials have been applying since 1980. There will be five circumstances in which an employer will not be regarded as a relevant employer, therefore enabling a person to bring a claim. Without the amendment, those relevant employer disregards that we wish to introduce will not apply in cases in which all periods of employment with the employer ended more than 20 years before the qualifying date.”
“Section 18 of the Social Security Administration Act 1992 (appeal on question of law) shall apply in relation to any question of law arising in connection with the determination by the Secretary of State of any claim under section 1 above as it applies in relation to any question of law arising in connection with the determination by the Secretary of State of any question within section 17(1) of that Act.”
