Every few years, the ICJ convenes a World Congress, where jurists from around the world work together to address a pressing human rights issue and agree normative principles and objectives in a public Declaration. These Declarations have frequently been used by inter-governmental bodies, including the United Nations, as well as bar associations, lawyers, academic centres and other human rights NGOs around the world. For example, the ICJ was responsible for the Declaration of Delhi on the rule of law in 1959, which set out the ICJ's conception of the Rule of Law as being dynamic.
