This talk will examine the legal nature of due diligence, namely whether it is a free-standing obligation under customary international law or a standard by which compliance with specific obligations may be assessed. It will be shown that there is a significant number of common elements in the analysis of due diligence as it is performed by international courts and tribunals, notwithstanding the specificities of the underlying subject matter. In doing so, this presentation will bring into question the validity of the recurring assumption that the content of due diligence differs fundamentally across various branches of international law.
