A 15-year-long legal tussle between lung cancer patients and Korean cigarette maker KT&G has come to an end with the nation's top court ruling in favor of the tobacco company.
The Supreme Court ruled this Thursday against a group of lung cancer patients who claimed their years-long smoking habit was the cause of their illness.
They had been demanding financial compensation from KT&G.
The dispute dates back to 1999 when the plaintiffs -- comprised of 30 people -- filed a damages suit against the company, alleging it used chemical additives to enhance the addictive effect of its cigarettes.
Two lower courts had earlier thrown out the plaintiffs' case.
One cited a lack of evidence to support the correlation between lung cancer and smoking, while the other would only acknowledge that smoking may increase the chance of contracting cancer.
