A class-action lawsuit accuses Disney of discriminating against people with disabilities after the company made major changes to the way it provides accommodations at its theme parks.

The lawsuit filed this month in Orange County Superior Court in California, alleges violations of the Americans with Disabilities Act, California’s Unruh Civil Rights Act and other laws.

Last summer, Disney imposed strict new limitations on who qualifies for its Disability Access Service, which allows people with disabilities to request a return time for one attraction at a time in order to avoid physically waiting in line at Disneyland and Disney World. With the changes, the company said that the accommodation is for those “who, due to a developmental disability like autism or similar, are unable to wait in a conventional queue for an extended period of time.”

The move to curtail eligibility came after Disney said that use of the Disability Access Service tripled in five years, becoming the most widely requested service at its theme parks and far exceeding the population for which it was intended.

However, since that time Disney has faced complaints from many people with disabilities who say they have been wrongly denied needed accommodations.

The lawsuit filed on behalf of Trisha Malone, a San Diego resident who was denied the Disability Access Service, alleges that the new criteria “systematically discriminate” by screening out people with physical disabilities like she has.

“By explicitly limiting DAS accommodations to guests with developmental disabilities who are ‘unable to wait in a conventional queue for an extended period of time,’ Disney unlawfully screened out individuals with physical disabilities, such as Plaintiffs Ms. Malone and other physically disabled guests that similarly prevented them from standing or waiting in long lines,” according to the complaint. “Disney must provide an equal opportunity for all individuals whose disabilities prevent them from using conventional queues, regardless of whether their disabilities are developmental, physical, or otherwise.”

Malone claims in the suit that she and others with disabilities were asked to disclose private medical information regarding the nature of their disabilities, symptoms and how the conditions impacted their ability to wait in line in public settings where other Disney staff and guests could overhear.

The complaint also alleges that Disney coerced people with disabilities into waiving their right to participate in any class-action litigation as part of the process of applying for the Disability Access Service.

Disney officials said that the Disability Access Service is one of many accommodations it offers to visitors with disabilities and that the company has assessed that this particular offering is necessary for only a limited percentage of guests.

“Disney is committed to providing a great experience for all who visit our theme parks, and particularly our guests with disabilities who may require special accommodations. Disney offers a broad range of effective disability accommodations and has worked extensively with experts to ensure that our guests’ individual needs are properly matched with the accommodation they require, and we believe the claims in this complaint are without merit,” the company said in a statement.

Just last month, Disney quietly updated its description of who qualifies for the Disability Access Service, seemingly loosening its criteria. The change was made after Malone’s attorney notified Disney of her claims.

However, DAS Defenders, a group that has pushed back against the more stringent rules, said that even people with developmental disabilities like autism have been declined the Disability Access Service since it was overhauled last summer and the group said that they have continued to hear about denials since the recent update took effect.

Disney previously faced years of litigation over a 2013 change to its disability accommodations, but ultimately prevailed.

The new class-action lawsuit names Walt Disney Parks and Resorts U.S., Inc. and Inspire Health Alliance, LLC, a health care provider Disney contracted to help assess eligibility for the Disability Access Service. It seeks changes to the Disability Access Service eligibility criteria to include all individuals with disabilities, damages of at least $4,000 per violation and other relief.
