Eben Self, an attorney for Aimee Krause, said that he filed suit in Orange County Court on his client's behalf late Thursday afternoon. In a complaint provided to the Orlando Sentinel by Self, Krause and her husband, Paul, claim that Disney World provided inadequate staff and security at the Mad Tea Party ride, where Krause was beaten by Victoria Walker of Anniston, Ala., in May 2007.

They also claim that the theme park did not adequately train its staff to recognize security threats such as those posed by Walker, that the park didn't remove her from the ride prior to the beating, in spite of parkgoers' requests, and that it bungled its investigation of the beating.

Paul Krause also is suing Disney World for the loss of his wife's support and companionship in the aftermath of the attack.

When reached Thursday evening, Disney spokeswoman Kim Prunty said she had no knowledge of Krause's litigation.

Last month, an Orange County jury convicted Walker of battery. During the trial, Krause and several witnesses testified that she was beaten and kicked by Walker because Walker was upset that she and members of her church group lost their place in line.

On the stand, Walker admitted that she grabbed Krause by the hair but denied she harmed her otherwise. She also said Krause provoked her.

Two doctors testified that Krause suffered permanent brain damage and psychological trauma in the beating, but the defense cast doubt on the severity of her injuries, noting that there was little physical evidence from tests to substantiate her claims.

The jury convicted Walker of battery, the least-serious charge she faced. The jury also delivered a special finding saying that Krause suffered minor injuries in the attack.
