The impact of the WHO Framework Convention on Tobacco Control in defending legal challenges to tobacco control measures

Background Since the WHO Framework Convention on Tobacco Control's (FCTC) entry into force, the tobacco industry has initiated litigation challenging tobacco control measures implemented by governments around the world, or supported others to initiate such litigation on its behalf. In defending their tobacco control measures against such litigation, governments have invoked their obligations and rights under the WHO FCTC. We assess the extent to which the WHO FCTC has provided legal weight to governments' defences against legal challenge. Methods We reviewed 96 court decisions concerning legal challenges to tobacco control measures, determining whether or not they cited the WHO FCTC and their outcomes. We then reviewed the cases where the WHO FCTC was cited, analysing how the WHO FCTC contributed to the resolution of the case. Results The WHO FCTC was cited in 45 decisions. Decisions both citing and not citing the WHO FCTC were largely decided in favour of governments, with 80% of WHO-FCTC-citing and 67% of non-WHO-FCTC-citing cases upholding the measure in its entirety and on every ground of challenge. In cases where it was cited, the WHO FCTC contributed to the resolution of the case in favour of governments by providing a legal basis for measures, demonstrating the measure's public health purpose, demonstrating the evidence in favour of a measure, demonstrating international consensus, demonstrating that a measure promotes or protects health-related human rights and demonstrating whether or not a measure is reasonable, proportionate or justifiable. Conclusions The way the WHO FCTC has been cited in court decisions suggests that it has made a substantial contribution to courts' reasoning in tobacco control legal challenges and has strengthened governments' arguments in defending litigation.
