Tobacco firms challenging court-ordered ads that say companies lied about dangers of smoking

The nation's largest tobacco companies are challenging court-ordered advertisements requiring the cigarette makers to say they lied about the dangers of smoking.

A federal judge had ordered the industry to pay for so-called corrective statements in advertisements in newspapers and on TV, websites and cigarette pack inserts.

In a brief filed Monday in the U.S. Court of Appeals for the D.C. Circuit, the companies argue that the statements would require them to "shame and humiliate themselves."

They also say the corrective statements go beyond "purely factual and uncontroversial" disclosures and are burdensome because the statements will be made in multiple channels.

The corrective statements are part of a case the government brought in 1999 under the Racketeer Influenced and Corrupt Organizations Act.
