This chapter examines Supreme People’s Court (SPC)’s judicial interpretation, which has been formally legalized as a source of law for adjudication, as well as its relationship with various other statutes in China’s legislative system. It points out that the inner logic of China’s legislation with different hierarchical status, as distinct from those of democratically elected parliamentary systems, is determined by the de facto distribution of legislative power within its authoritarian regime, where the SPC has become a significant player in exercising legislative power in a way that has largely evolved beyond its constitutional settings. In particular, it investigates the unique inner logic of SPC’s judicial interpretations, which have become a de facto primary source of law for adjudication in practice.

This chapter explores the unique function and role of judicial documents – a significant form of informal state law, as distinguished from formal statutory laws – in China’s legislative enterprise. In particular, it examines why and how, with no explicit statutory delegation, the judicial lawmaking practice of producing judicial documents has become embedded in the adjudication of China’s courts. It accordingly proposes a twilight theory of China’s judicial documents that explains why the practice of judicial lawmaking through producing documents exists in a twilight zone between legal and illegal and is suitable for China’s politically resilient authoritarian regime. Moreover, it demonstrates how the judicial document can be referred to effectively by judges in adjudication. It further investigates the extent to which the judicial document has enabled the court, under the dual leadership of the superior court and the local Party committee, to efficiently and effectively respond to the subnational diversity and the differences of local politics.
