This article investigates dynamics of mobilization over environmental and human rights norms in the context of undemocratic governments.We test the suggestion in norm diffusion theories that the success of domestic struggles in this context depends on the level of internalization of norms brought about by international pressure. We find that the internalization (or lack thereof) of global norms by the Government of Sudan does not explain its recognition of environmental justice claims in this case. Furthermore, the various litigation efforts pursued by affected people outside Sudan did not influence their campaign. However, a combination of the political climate in the country and a unique political interplay between the government and a distinct group of the affected people may have led to the singular success of their campaign. We use a combination of discourse analysis, legal analysis, norm mapping, and semi-structured interviews to reach conclusions.
