Existing scholarship of China’s legal institutions has primarily focusedon individual institutions, such as the court, the police, or the legalprofession. This article proposes a relational approach to the study ofpolitical-legal institutions in China. To understand the order and exercise ofpower by various political-legal institutions, the relational approachemphasizes the spatial positions of actors or institutions (the police, courts,lawyers, etc.) within the broader political-legal system and their mutualinteractions. We suggest that the changing ideas of the Chinese leadership aboutthe role of law as an instrument of governance have shaped the relations betweenvarious legal and political institutions. The interactions of thesepolitical-legal institutions (e.g. the “iron triangle” of thepolice, the court and the procuracy) further reveal the dynamics of powerrelations at work.
