Abstract
This article analyses the conflicting professional ethical demands imposed on judges to, on the one hand, faithfully apply the existing law of the land and, on the other hand, do justice in the face of urgent global challenges such as ensuring an equal access to life-saving medicines. After establishing the precise nature of the professional ethical duties of judges (as opposed to those of lawyers) and noting the tensions they face when the duty of applying the law prevents them from complying with the duty of delivering material justice in the domain of access to medicines, the article then analyses the way this issue plays out in Latin America, a región where judicially-mandated access to medicines has been common. The article concludes by arguing that the Latin American experience suggests that judges around the world should take seriously the need to find a balance between their duty of deference towards public health authorities in this domain (when this is mandated by legislation), and the duty to do justice to individuals who cannot afford live-saving medicines.
