This course focuses on the law of population health, examining the legal powers and duties of federal, state, and local governments to promote and protect the health of their communities, as well as the constraints placed on those powers to protect individual rights. A course designed specifically for students with no legal training, it introduces students to the multiple ways the law can be used as a tool to advance public health, including through direct and indirect regulation to alter the information and built environments; through governments’ power to tax and spend to fund public health programs and services, and in ways that can influence individual and corporate behavior; and through the courts. Students gain basic proficiency in finding, reading, and interpreting primary legal sources, in applying the law to public health problems, and in identifying ways to most effectively influence legislative, administrative, and judicial lawmaking processes to promote and protect (and also thwart efforts to impede) public health.
