 Sections 1 and 2 came into force on royal assent on 25 July 2006 (s.16(1)).Section 3 reverses the common law rule on allocation of damages in various mesothelioma claims arising from unlawful exposure to asbestos.In 2002, the House of Lords ruled in "Fairchild v Glenhaven Funeral Services Ltd" that, where several parties had unlawfully exposed the claimant to asbestos and risk of pleural and peritoneal mesothelioma, all were liable for his injury, even though the claimant could not prove which individual party had provided the asbestos fibers that cause the disease.
