COVID Justice and Accountability Act This bill provides a cause of action for harm suffered as a result of a violation of certain federal laws relating to COVID-19 (i.e., coronavirus disease 2019) and suspends certain predispute arbitration agreements and joint-action waivers during the COVID-19 public health emergency. Specifically, individuals may bring a cause of action in U.S. district court against any person for harm suffered as a result of a violation of, or a failure to comply with, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) or the Families First Coronavirus Response Act. Further, during the COVID-19 public health emergency period and 180 days thereafter, no predispute arbitration agreement or joint-action waiver (an agreement to waive the right to participate in a joint, class, or collective action) is valid or enforceable with respect to employment, consumer, antitrust, or civil rights disputes.
