Sharp v Port Kembla RSL Club: establishing causation of laryngeal cancer by environmental tobacco smoke.

A New South Wales Supreme Court jury has decided that environmental tobacco smoke (ETS) can cause or materially contribute to the development of laryngeal cancer. Evidence presented that ETS may cause or materially contribute to laryngeal cancer included the molecular genetics of tobacco-smoke-induced carcinogenesis, and two relevant epidemiological studies. The plaintiff's exposure to ETS was established indirectly, on the basis of occupational history involving work as a bar attendant in licensed premises. The jury's decision seems likely to encourage other "passive smoking" cases, and may result in measures to reduce occupational exposure to ETS.
