This essay reflects upon the last thirty-five years of public health law. Part One begins by discussing the growth and maturation of the field of public health law since the 1980s. Part Two examines current challenges facing public health law, focusing on those posed by the conservative legal movement and a judiciary that is increasingly skeptical of efforts to use law to improve health and mitigate health inequities. Part Three discusses potential responses to the increasingly perilous judicial climate, including thoughts that emerged from a convening held on the subject by the Act for Public Health Partnership in May 2024.
