The Tokyo High Court on Wednesday dismissed an appeal filed by former smokers, some now deceased, who were each demanding 10 million yen in compensation from Japan Tobacco Inc. and the government for tobacco-induced illnesses.

The six plaintiffs claimed to have contracted lung cancer, throat cancer and emphysema from smoking cigarettes for periods ranging from 33 to 50 years.

Three of the plaintiffs died after the lawsuit was filed in 1998 and family members have continued to press their cases.
