Air Evac EMS, Inc. v. Sullivan
This case addresses whether the Airline Deregulation Act (ADA) preempts provisions of the Texas Workers' Compensation Act (TWCA) that regulate the reimbursement rates for air ambulance services. Plaintiff Air Evac EMS, Inc. argued that the TWCA's restrictions on its charges for services to workers' compensation patients are preempted by the ADA. The State Defendants (Texas Commissioner of Insurance and Texas Commissioner of Workers' Compensation) and Intervenor Defendants (multiple workers' compensation insurers) contended against preemption, citing a presumption against federal interference with state police powers and the McCarran-Ferguson Act. The court found that the ADA's preemption provision, which broadly prohibits state laws related to an air carrier's prices, routes, or services, applies to the TWCA's compensation scheme for air ambulance providers. Furthermore, the court determined that the McCarran-Ferguson Act does not shield the TWCA provisions because they regulate the 'business of insurance companies' rather than the 'business of insurance.' As a result, the court granted Air Evac's motion for summary judgment, denied the defendants' motions, and issued a permanent injunction prohibiting the State Defendants from enforcing the challenged TWCA provisions against Air Evac.
