In the face of unprecedented global challenges, effective global cooperation increasingly requires a partnership between state and non-state actors. Many international institutions now involve non-state actors in arenas that were once the exclusive province of states. The paper analyzes the evolution of civil society participation in the governance of international institutions and highlights the shift from a model based on consultation toward a model of multistakeholder governance. The paper argues that consultation is a less effective approach to involving civil society in achieving the mission of these institutions and suggests that more robust forms of multi-stakeholder participation by civil society can foster greater accountability and better deliberation. It analyzes competing claims about the desirability of including civil society in the governance of international institutions and suggests that an emerging constituency model can promote more effective multi-stakeholder governance. Constituency structures are already central features of several global health institutions and are now being contemplated by institutions in other sectors, including by the Education for All—Fast Track Initiative.

Multi-stakeholder approaches to governance are likely to become more widespread in the years to come in order to harness the contributions of a plethora of private actors engaged in responding to a wide range of global challenges. Even with enhanced cooperation between states, it is increasingly clear that non-state actors are essential to responding to key challenges across a wide range of sectors. Although it is possible to imagine expanded cooperation between state and non-state actors without opening up the governance structures of international institutions, it is less likely that these institutions will be successful in the longrun without a shift toward greater multi-stakeholder involvement in the institutions themselves.
