Constitutional Authority to Regulate the Privacy of State-Collected Contact-Tracing Data [June 26, 2020] [open pdf - 640KB]
Form the Document: "Amid the ongoing COVID-19 [coronavirus disease 2019] pandemic, several states have developed and promoted contact-tracing mobile device apps to identify individuals who may have had contact with infected persons. Additionally, the two largest manufacturers of mobile device operating systems, Apple (iOS) and Google (Android), have announced plans to release application programming interfaces (APIs) to 'enable interoperability between Android and iOS devices using apps from public health authorities.' Several bills in the 116th Congress would regulate the privacy of information collected through such contact-tracing apps."
