This brief article is a review of Global Health Law by Lawrence O. Gostin (Harvard University Press, 2014). Building on his background in human rights and public health law, Gostin seamlessly integrates those fields into his discussion of how the international system attempts to address the major health-related challenges of our time. Gostin focuses much of his book on the deep health disparities found around the globe, and he articulates a powerful vision of “global health with justice” that includes an expansive understanding of the “right to health” found in various international agreements. This review argues that although Gostin’s vision is profound and inspiring, Global Health Law may underestimate the many challenges and roadblocks inherent in our decentralized system of global governance.
