A woman ordered to pay $222,000 for downloading and sharing music files will appeal the case.
Jammie Thomas said on her Myspace.com blog that the appeal was announced by her lawyer, Brian Toder, in an interview with CNN.
"My attorney announced, on national television, with the RIAA watching I'm more than certain, we're going to appeal," she wrote in the blog entry. Winning the appeal will "stop RIAA in their tracks," she wrote.
Thomas was ordered last week by a jury in the US District Court for the District of Minnesota to pay $222,000 in damages to six music labels, representing $9,250 for each of 24 songs illegally downloaded and shared over the Kazaa file-sharing network.
The case against Thomas was filed by the Recording Industry Association of America (RIAA), an umbrella group representing music labels.
The verdict was a sign that the RIAA might emerge victorious in some of the more than 20,000 lawsuits it has filed against people for alleged internet copyright infringement.
Thomas, who lives in Brainerd, Minnesota, has also set up a website to raise funds to cover legal expenses. As of Monday evening supporters had donated $3,853.
Neither RIAA nor attorney Toder, of the Chestnut and Combronne law firm, could not be reached for comment.
The music labels involved in the suit include Capitol Records, Sony BMG Music Entertainment and Warner Bros Records.
