British American Tobacco launched legal action against the Australian government on Thursday, challenging the country’s tough new law that bans logos from cigarette packs.

The move comes less than two weeks after Australia’s Parliament passed the legislation, which forces tobacco companies to remove their distinctive colors and logos and instead print their brand names in a tiny font on drab, olive-green packs. The packs will also feature graphic images highlighting the negative effects of smoking, such as cancer-riddled mouths.
