This chapter flashes back to the first days of Sophie’s employment at the ICJ registry, and sees her and her girlfriend Norma mull over the socio-professional features of the international judicial community. The chapter lays the theoretical foundations of the book and provides the reader with pointers to interpret the unfolding of judicial proceedings. The international judicial community has a twofold structure, at once cooperative and competitive. On the one hand, its members work together to secure control on courts and tribunals and insulate their internal activities from outside interference. On the other hand, community members ceaselessly strive to maximize their relative capital in a ruthless struggle for authority and prestige. The practices of the community are patterned, as they present regularities over time; they are competent, as they rest on collective background knowledge; and they weave together the discursive and the material world. Thus, community practices are the vehicle of both continuity and change, constraint and freedom in international adjudication.
