In this blog post, I address some pertinent issues regarding due diligence as addressed by the ICJ, as well as ITLOS and the IACtHR. In particular, I focus on the relationship between obligations of result and obligations of conduct, the nature of due diligence, factors to determine its content, and the legal consequences of not acting with the required diligence.
