This special issue of the Journal presents articles written by a group of public health law scholars who belong to the George Consortium, which is dedicated to strengthening the capacity of academics, practitioners, and advocates working to advance public health through law. The group's operating premise is that law is fundamental to the origin, understanding, and delivery of public health services, as well as to the social determinants of health. Depending on its content and form, law can improve the likelihood that populations, nationally and globally, can lead healthy, long, and productive lives, or it can hinder their ability to do so.
