This article aims to reveal the implications and significance of recent practices of the Human Rights Committee (hrc) in monitoring the human rights situation pertaining to peacekeeping operations; it also seeks to highlight the hrc’s roles in relation to either United Nations (un) member states’ or the un’s accountability over peacekeeping operations. The contribution is inspired by the current study and development of the accountability of international organisations. Empirical analysis shows the potential role of the hrc as one of the monitoring bodies of human rights situations in peacekeeping operations. A parallel question arises: what are the legal bases for the hrc monitoring of un member states’ or the un’s accountability with regard to peacekeeping operations? Considering the matter from various angles based on the concept of accountability reveals the background to and implication of the legal bases in question.
