In the early 1990s, the Commonwealth reformed its political structure to allow interference in domestic affairs of member states. This article examines whether such an institutional transformation has helped the organization to fulfil its purpose to work in the common interests of member countries and of their people. The article demonstrates that, while, as a consequence of post-Cold War globalization, concerns about the Commonwealth's political credibility and public perception have relaxed Commonwealth leaders' reluctance to accept legally binding norms of the organization, strong resistance to Commonwealth interference in internal affairs exists among developing member states. It is argued that, because the new Commonwealth political structure lacks legitimacy and is contrary to the real interests of the majority of members, institutionalizing the Commonwealth has not contributed to the formation of a collective identity among Commonwealth members and to the resolution of the problem of inequality within and without the organization.
