This thesis explores the connections between theories of justice and international mediation. Modern theories of justice examine how to achieve a just resolution of conflict in a bargaining framework. These theories can examine, therefore, the international mediation process because it is a political bargaining process that has become triadic. Against the prevailing views in the mediation literature, this thesis argues that normative standards of justice are possible to be placed on the mediator and the participants to an international mediation. Evaluative criteria for a just mediation are developed to test the real world application of these standards. The criteria are applied to two mediations, the Dayton peace talks, and the Oslo Back Channel. These case studies show that it is possible to examine justice in international mediation.
