(18) Lawsuits against health care workers and facilities pose a similarly dangerous risk to interstate commerce. Interstate commerce will not truly rebound from this crisis until the virus is defeated, and that will not happen unless health care workers and facilities are free to combat vigorously the virus and treat patients with coronavirus and those otherwise impacted by the response to coronavirus. (19) Subjecting health care workers and facilities to onerous litigation even as they have done their level best to combat a virus about which very little was known when it arrived in the United States would divert important health care resources from hospitals and providers to courtrooms. (20) Such a diversion would substantially affect interstate commerce by degrading the national capacity for combating the virus and saving patients, thereby substantially elongating the period before interstate commerce could fully re-engage. (21) Congress also has the authority to determine the jurisdiction of the courts of the United States, to set the standards for causes of action they can hear, and to establish the rules by which those causes of action should proceed. Congress therefore must act to set rules governing liability in co­ro­na­vi­rus-related lawsuits. (22) These rules necessarily must be temporary and carefully tailored to the interstate crisis caused by the coronavirus pandemic. They must extend no further than necessary to meet this uniquely national crisis for which a patchwork of State and local tort laws are ill-suited. (23) Because of the national scope of the economic and health care dangers posed by the risks of coronavirus-related lawsuits, establishing temporary rules governing liability for certain coronavirus-related tort claims is a necessary and proper means of carrying into execution Congress’ power to regulate commerce among the several States. (24) Because Congress must safeguard the investment of taxpayer dollars it made in the CARES Act and other coronavirus legislation, and ensure that they
