Legalized Dispute Resolution: Interstate and Transnational

We identify two ideal types of international third-party dispute resolution: interstate and transnational. Under interstate dispute resolution, states closely control selection of, access to, and compliance with international courts and tribunals. Under transnational dispute resolution, by contrast, individuals and nongovernmental entities have significant influence over selection, access, and implementation. This distinction helps to explain the politics of international legalization—in particular, the initiation of cases, the tendency of courts to challenge national governments, the extent of compliance with judgments, and the long-term evolution of norms within legalized international regimes. By reducing the transaction costs of setting the process in motion and establishing new constituencies, transnational dispute resolution is more likely than interstate dispute resolution to generate a large number of cases. The types of cases brought under transnational dispute resolution lead more readily to challenges of state actions by international courts. Transnational dispute resolution tends to be associated with greater compliance with international legal judgments, particularly when autonomous domestic institutions such as the judiciary mediate between individuals and the international institutions. Overall, transnational dispute resolution enhances the prospects for long-term deepening and widening of international legalization.
