As COVID-19 spread across the country, governors and health officials invoked their emergency powers to order physical distancing measures designed to reduce social interactions and slow the spread of the disease. Several of these measures, such as stay-at-home orders, business and school closures, public gathering limits, face covering requirements, and others, are being challenged in federal and state courts. Many of the legal challenges include claims of executive overreach and misuse of emergency power as well as allegations of violating individual rights protected by the U.S. Constitution.
