The Birth of the New Justice / Oxford Studies in Modern European History (PDF)

Until 1919, European wars were settled without post-war trials, and individuals were not punishable under international law. After World War One, European jurists at the Paris Peace Conference developed new concepts of international justice to deal with violations of the laws of war. Though these were not implemented for political reasons, later jurists applied these ideas to other problems, writing new laws and proposing various types of courts to maintain the post-World War One political order. They also aimed to enhance internal state security, address states' failures to respect minority rights, or rectify irregularities in war crimes trials after World War Two.

The Birth of the New Justice shows that legal organizations were not merely interested in ensuring that the guilty were punished or that international peace was assured. They hoped to instill particular moral values, represent the interests of certain social groups, and even pursue national agendas. When jurists had to scale back their projects, it was not only because state governments opposed them. It was also because they lacked political connections and did not build public support for their ideas. In some cases, they decided that compromises were better than nothing.

Rather than arguing that new legal projects were spearheaded by state governments motivated by "liberal legalism," Mark Lewis shows that legal organizations had a broad range of ideological motives - liberal, conservative, utopian, humanitarian, nationalist, and particularist. The International Law Association, the International Association of Penal Law, the World Jewish Congress, and the International Committee of the Red Cross transformed the concept of international violation to deal with new political and moral problems. They repeatedly altered the purpose of an international criminal court, sometimes dropping it altogether when national courts seemed more pragmatic.
