This collection of datasets on LawAtlas.org includes data that capture laws and policies related to the authority to act for the public’s health. The datasets provide an overview of laws that limit, expand or reallocate the authority of a governor, state health agency, or state health official to act during emergencies and otherwise. Many of the datasets in this collection were created through the Act for Public Health initiative, a group of organizations and experts applying their decades of experience in public health law and policy work to help push back against legislative attempts to block public health officials’ ability to do their job.
