The 10th U.S. Circuit Court of Appeals has taken under advisement arguments in an Oklahoma woman's lawsuit against the U.S. Tobacco Co. alleging her son died from cancer caused by snuff.

Attorneys for Betty Marsee of Ada, Okla., and U.S. Tobacco appeared before the appellate bench Thursday morning in Salt Lake City, where the 10th Circuit has been hearing cases this week.Utah U.S. District Court officials said it could be several months before the 10th Circuit rules on Ms. Marsee's appeal.

In June 1986, a federal jury in Oklahoma City ruled that the tobacco company was not responsible for the death of 19-year-old Sean Marsee. The youth died from tongue cancer that his mother claimed was caused by his use of snuff.

Mrs. Marsee alleged in her $147 million lawsuit that her son's use of snuff since the age of 12 caused him to develop tongue cancer in 1983. He died in February 1984 following three operations.

The landmark trial received national attention because of its potential impact on the tobacco industry and the use and promotion of smokeless tobacco.
