Breitenbach: She took the decision [to ban tobacco sales] knowing she would be giving rise to illicit trade, but it was taken to alleviate burden on healthcare system. The minister would not ban legal sales to fuel illicit trade.   

Breitenbach rejects the idea that the ban has simply given rise to the illicit market. In fact, the illicit trade, according to Breitenbach is "an unfortunate reality" in South Africa. 

Advocate Andrew Breitenbach, on behalf of government, says the intention of the ban is to reduce the incidence of smoking in order to reduce pressure on health services.

Mix of Covid-19 and other illnesses creates a 'toxic concoction' court hears in BATSA case

On Thursday advocate Karrisha Pillay SC, argued on behalf of the minister that the ban seeks to reduce - and not completely eliminate - incidents of smoking and to free up critical resources to respond to severe cases of Covid-19.

"This court's role is not to assess which side's scientific evidence is better, but the question is whether, having regard to the evidence the minister had regards to, it can be said that she made a reasonable and rational decision," said Pillay.

Pillay says the court must consider the evidence of the WHO on the effects of quitting [smoking]: It is therefore logical that stopping smoking will have beneficial effect to both smokers and non-smokers. 

Pillay turns to issue of whether cessation in smoking will lessen or reverse disease progression of Covid-19. She is relying on studies to make the point: Chance of infection for someone who has quit smoking is not clear, given how new Covid-19 is, but there is clear evidence of benefits in the long and short term for people who quit.

Court is currently on a tea adjournment. 

Pillay says it's not for the court to decide which science is best. The consideration should be whether it can be said that the decision to ban the sale of cigarettes is "reasonable, rational and a necessary decision."

Pillay quotes from New England Journal of Medicine study which found that former and current smokers have a higher propensity of contracting Covid-19. Pillay says the minister considers the study "the best in the world". 

Smokers are more likely to develop disease with Covid-19, the statement reads, available research shows that smokers are also at higher just.

WHO is constantly evaluating new research.  

Question approached: Whether the justification of the ban by Dlamini-Zuma was born out of documents and information relied on, the four sources are named.

These include WHO statements - specifically dealing with tobacco use and Covid-19, dated 11 April 2020.

Adv Karrisha Pillay for the Cooperative Governance Minister Nkosazana Dlamini-Zuma highlights the increased behavioural risk behaviours associated with the use of tobacco and the justification the ban.
