British American Tobacco has vowed to sue over Australia’s cigarette plain packaging law if the legislation is enacted.  On November 10, the Australian Senate passed the world’s first plain packaging law and the lower house of parliament still needs to vote on it.  If approved, the law is set to take effect December 2012.  The law will prohibit tobacco companies from displaying their logos on cigarette packages, and will require cigarettes to be sold in drab brown packs with prominent health warnings.  British American Tobacco claims it is unconstitutional to remove trademarks and other intellectual property without compensation and has threatened to sue in Australia’s top court to repeal the law.  The industry has also threatened to resort to lower product pricing to differentiate brands.  Learn more.
