There is no formal hierarchy between, or international rule of precedent applicable to, the three regional human rights systems and the eight UN Human Rights Treaty Bodies with active competence to entertain individual complaints. By scrutinising the practice of duplicative proceedings of UN Treaty Bodies (UNTBs), this article makes the argument that the res judicata and lis pendens principles have not prevented the UNTBs from reviewing cases previously examined by a regional human rights court. In doing so, the case is made that while the UNTBs usually defer to regional courts’ factual and legal findings when analyzing cases with the same parties, substantive rights, facts and events, judgments that apply the margin of appreciation doctrine are much more at risk of being revised and contradicted by UN Human Rights Treaty Bodies. Distinct opportunities for horizontal dialogue between UNTBs and regional human rights courts are thus opened.

推迟还是修改？联合国条约机构与区域人权法院在重复法律程序中的横向对话

三个区域人权系统和八个联合国人权条约机构之间没有正式的等级制度，也没有适用的国际先例规则，它们具有受理个人投诉的积极权限。通过审视联合国条约机构 (UNTB) 重复诉讼的做法，本文论证了既判力和待决原则并未阻止 UNTB 审查先前由区域人权法院审查过的案件。这样做的理由是，虽然 UNTB 在分析涉及相同当事方的案件时通常会遵从地区法院的事实和法律调查结果，但适用判断余地原则的实质性权利、事实和事件的判决风险更大被联合国人权条约机构修订和抵触。
