This paper discusses the constructivist, negotiated perspective to INGO accountability. According to this perspective, INGO accountability is a process of mutual negotiations between different INGO stakeholders who hold different accountability demands. Acknowledging that this perspective provides a good starting point for a better understanding of INGO accountability, we comment on this conceptualization of INGO accountability. Through an analysis of accountability instruments and procedures, we examine closely how the demands of the INGO's stakeholders are embedded in particular relationships of accountability which are sustained by particular accountability logics. From this analysis, we point out that, due to the differences that exist between these accountability logics, processes of negotiation are likely to be filled with complex tensions and trade-offs. Moreover, as some accountability logics are much clearer and more compelling than others, a constructivist perspective on INGO accountability does not automatically coincide with an understanding of INGO accountability in which primordial importance is given to the beneficiaries.
