Teleological Interpretation of Constituent Instruments in the Time of Accountability of International Organizations

International law has seen challenges in terms of lack of applicable norms governing conducts of international organizations (IOs) while there have been an increasing number of cases where their activities resulted in unjustifiable situations causing impacts on or damage to individuals without any access to sufficient remedies. This study focuses on the issue of IOs accountability and seeks positive legal bases for accountability, on which IOs’ obligations to protect human rights or to ensure the Rule of Law in their internal legal orders are based, examined through the lens of teleological interpretation of their constituent instruments. This study deepens and generalizes Benvenisti’s (2013) view of referring to functional necessity as a legal basis for accountability. Considering IOs constituent instruments in this manner allows to identify limits over their powers and rectifying their accountability deficits.
