Gostin's timely book offers the first systematic definition and theory of public health law. Basing his definition on a broad notion of the government's inherent responsibility to advance the population's health and well-being, he develops a rich understanding of the government's fundamental powers and duties. By analyzing constitutional powers and limits, as well as statutory, administrative, and tort law, Public Health Law vividly shows how law can become a potent tool for the realization of a healthier and safer population.
