Confederacao Nacional do Comercio de Bens, Servicos e Turismo v. Paraná

The National Confederation of Commerce of Goods, Services, and Tourism filed a lawsuit against the Paraná (state-level) tobacco control law, which prohibits smoking in public or private collective environments in the state of Paraná. The Court unanimously held that the state legislative assembly did not exceed its competence to legislate public health. The Court also concluded that the state law did not offend fundamental freedoms since it did not prohibit the exercise of the individual's right to consume tobacco products. Furthermore, the Court affirmed that the restriction of using tobacco products in collective enclosed environments respected the rights of non-smokers and the adequate protection of health.
