MIAMI — The nation’s No. 2 cigarette maker is vowing to fight a jury verdict of $23.6 billion in punitive damages in a lawsuit filed by the widow of a longtime smoker who died of lung cancer.

R.J. Reynolds Tobacco executive J. Jeffery Raborn has called the damages awarded by a Pensacola jury “grossly excessive and impermissible under state and constitutional law.”

“This verdict goes far beyond the realm of reasonableness and fairness, and is completely inconsistent with the evidence presented,” Raborn, a company vice president and assistant general counsel, said in a statement. “We plan to file post-trial motions with the trial court promptly, and are confident that the court will follow the law and not allow this runaway verdict to stand.”

One of the widow’s attorneys said the verdict Friday night sends a powerful message to tobacco companies.

“The jury wanted to send a statement that tobacco cannot continue to lie to the American people and the American government about the addictiveness of and the deadly chemicals in their cigarettes,” said Christopher Chestnut, one of the attorneys representing Cynthia Robinson.

The case is one of thousands filed in Florida after the state Supreme Court in 2006 threw out a $145 billion class action verdict. That ruling also said smokers and their families need only prove addiction and that smoking caused their illnesses or deaths.
