Debates about human rights have often questioned their potential for generating rights at national levels. In this article, we use the case of irregular migrants’ access to health care in the United Kingdom and France to explore the extent to which international human rights influence national health care provisions for irregular migrants. We explore the extent to which health care access and provision for irregular migrants in these two countries is in agreement with international human rights. In so doing, we examine what constitutes an infringement of the international human right to health care. Finally, we sketch out some hypotheses about the role played by different state structures in the implementation of human rights norms, comparing the United Kingdom with France. We argue that, although international human rights often have a largely symbolic role in nation-state jurisdiction, they may sometimes represent a force for change.
