UN Peacekeeping Operations and Article 7 ARIO: The Missing Link

Peacekeeping operations conducted by international organizations raise difficult questions of international responsibility. In principle, breaches of international law committed by national contingents serving on such operations may be attributed either to the international organization leading the operation or to the State to which the personnel implicated in the wrongful conduct belongs.
