A Florida jury has ordered cigarette maker Philip Morris USA to pay $300 million in damages to a 61-year-old ex-smoker named Cindy Naugle who is wheelchair-bound by emphysema.

The Broward Circuit Court jury on Thursday assessed $56.6 million in past and future medical expenses against the company, part of Altria Group, as well as $244 million in punitive damages.

The verdict is the largest of the so-called Engle progeny cases that have been tried so far, both sides said.

Philip Morris will seek further review of the verdict because of "numerous erroneous rulings by the trial judge," Philip Morris spokesman Murray Garnick said in a statement.

"We believe that the punitive damages award is grossly excessive and a clear violation of constitutional and state law," Garnick said.

Naugle's lawsuit was among about 8,000 cases filed in the wake of a 2006 Florida Supreme Court decision that tossed out a massive class action against the tobacco companies. The case, known as Engle v. RJ Reynolds, resulted in the largest verdict in US history at trial - $145 billion.
