This special issue proposes a relational approach to the study of judicial politics outside of Western democracies. The articles illuminate how common political interests, ideas, social identity, family and professional ties and even patron-client obligations between judges and other actors shape a variety of phenomena of interest to the study of judicial institutions, in terms of how the judiciary is organised and administered, how judges are appointed and make decisions, and the prospects for judicial reform. Collectively, the articles explore the informal dimension of judicial politics in a systematic fashion, through rich empirical case studies in very different contexts. Thus, they help structure a new comparative agenda for research on informal judicial politics outside of the West.
