Global Judicial Opinions Regarding Government-Issued COVID-19 Mitigation Measures

Laws play an important role in emergency response capacity. During the COVID-19 outbreak, experts have noted both a lack of law where it is needed and a problematic use of laws that exist. To address those challenges, policymakers revising public health emergency laws can examine how existing laws were used during the COVID-19 response to address problems that arose during their application. Judicial opinions can provide a source of data for this review. This study used legal epidemiology methods to perform an environmental scan of global judicial opinions, published from March 1 through August 31, 2020, from 23 countries, related to government-issued COVID-19 mitigation measures. The opinions were coded, and findings categorize the measures based on: (1) the World Health Organization's May 2020 publication, Overview of Public Health and Social Measures in the Context of COVID-19, and (2) related legal challenges brought in courts, including disputes about authority; conflicts of law; rationality, proportionality, or necessity; implementation; and enforcement. The findings demonstrate how judicial review of emergency measures has played a role in the COVID-19 response. In some cases, court rulings required mitigation measures to be amended or stopped. In others, court rulings required the government to issue a measure not yet in place. These findings provide examples for understanding issues related to the application of law during an emergency response.
