Instead, the Food and Drug Administration will go back to the drawing board and create labels to replace those that included images of diseased lungs and the sewn-up corpse of a smoker, according to a letter from Attorney General Eric Holder obtained by The Associated Press. The government had until Monday to ask the U.S. Supreme Court to review an appeals court decision upholding a ruling that the requirement violated First Amendment free speech protections.

"In light of these circumstances, the Solicitor General has determined … not to seek Supreme Court review of the First Amendment issues at the present time," Holder wrote in a Friday letter to House Speaker John Boehner notifying him of the decision.

Some of the nation's largest tobacco companies, including R.J. Reynolds Tobacco Co., sued to block the mandate to include warnings on cigarette packs as part of the 2009 Family Smoking Prevention and Tobacco Control Act that, for the first time, gave the federal government authority to regulate tobacco. The nine labels originally set to appear on store shelves last year would've represented the biggest change in cigarette packs in the U.S. in 25 years.
