A legal challenge by the tobacco industry against imposing new rules for standardized packaging in the UK has failed.
Philip Morris International, British American Tobacco, Imperial Tobacco and Japan Tobacco International had challenged the legality of the new regulations, which mean all new cigarette packs sold in Britain will have to be olive green.
‘All new cigarette packs sold in Britain will have to be olive green with health warnings on the front and back of every pack and additional warnings on the top.’
Shops will have 12 months to sell existing packets.
"The regulations were lawful when they were promulgated by parliament, and they are lawful now in the light of the most up-to-date evidence," Judge Nicholas Green said in the ruling.
Cancer Research UK's chief executive Harpal Kumar said, "This is an important milestone in our efforts to reduce the devastating toll that tobacco exerts on so many families every day.
"It's the beginning of the end for packaging that masks a deadly and addictive product," he said.
The anti-smoking campaign group ASH said the tobacco companies had suffered a "humiliating defeat," adding that the judgment would help other countries looking to introduce similar policies.
Australia, France, and Ireland have already done so.
The European Court of Justice earlier this month ruled that the Tobacco Product Directive is lawful.
Under the directive, health warnings must cover 65 percent of the front and back of every pack of cigarettes, with additional warnings on the top.
The directive also allowed Britain to go further and introduce its own regulations requiring all tobacco packaging to be the same color -- olive green -- and with large images designed to act as health warnings.
After the European Court of Justice ruling, a British health ministry spokesman said: "Smoking is the biggest cause of premature mortality and kills over 100,000 people every year in the UK."
