The justices on Monday rejected Ford Motor Co.'s challenge to the portion of the award, $55 million, that was intended as punitive damages. Ford argued that it should not be punished because its design of the vehicle met federal safety standards.
A California state appeals court earlier rejected Ford's contention and upheld the award to Benetta Buell-Wilson.
She was driving on an interstate east of San Diego in January 2002 when she swerved to avoid a metal object and lost control of her 1997 Explorer, which rolled 4 1/2 times. The mother of two was paralyzed from the waist down when the roof collapsed on her neck, severing her spine.
A jury initially awarded Buell-Wilson $369 million, including $246 million in punitive damages but courts twice cut the size of the award. The jury concluded that Ford knew the Explorer had design defects that made it prone to rollovers in emergency maneuvers and the collapse of its roof.
The case is Ford v. Buell-Wilson, 09-297.
