British American Tobacco (Kenya) filed a lawsuit claiming that Kenya’s Tobacco Control Regulations are unconstitutional. The court ruled against the tobacco company, finding that the process of developing the regulations was lawful and conducted with sufficient participation by the tobacco industry. The court upheld nearly all elements of the Regulations, which are designed to implement the Tobacco Control Act, including:

- a 2% annual contribution by the tobacco industry to help fund tobacco control education, research, and cessation;
- picture health warnings;
- ingredient disclosure;
- smoke-free environments in streets, walkways, verandas adjacent to public places;
- disclosure of annual tobacco sales and other industry disclosures; and
- regulations limiting interaction between the tobacco industry and public health officials.

The court specifically noted that the Tobacco Control Act and Regulations are intended to comply with the Framework Convention on Tobacco Control. Additionally, the court acknowledged the harm caused by tobacco products and stated it would make its decision within the context of a public health system balanced against the commercial rights of the tobacco company.

The court struck down a few minor elements of the regulations, ruling that (1) the tobacco industry is not required to provide evidence of its market share to the government; and (2) that penalties for violation cannot exceed the maximums authorized by law.

The court ruled that the regulations should take effect six months after the date of the decision.
