An appeals court on Wednesday denied the federal government's request to reconsider a decision blocking a requirement that tobacco companies put large graphic health warnings on cigarette packages to show that smoking can disfigure and even kill people.

In its filings, the U.S. Court of Appeals in Washington, D.C., did not provide any reason denying the request for the full court or a panel to rehear the case.

In August, a three-judge panel affirmed a lower court ruling blocking the Food and Drug Administration mandate, saying it ran afoul of the First Amendment's free speech protections.

A Justice Department spokesman declined to comment. The government has 90 days to appeal the decision to the U.S. Supreme Court.

Some of the nation's largest tobacco companies, including R.J. Reynolds Tobacco Co., sued to block the mandate to include warnings to show the dangers of smoking and encouraging smokers to quit lighting up. They argued that the proposed warnings went beyond factual information into anti-smoking advocacy. The government argued the photos of dead and diseased smokers are factual.
