This concluding chapter outlines the contours of the Party-state and develops a conceptual framework to explain its distinctive mode of governance. At its core is a dual normative system: a legal system grounded in popular sovereignty is overseen and constrained by a power-based normative system designed to uphold the absolute authority of the Party Center—an organizing principle essential to maintaining the structural integrity of the Party-state. The chapter argues that the governance logic of the Party-state is best captured by the theory of Normalized Political Prerogative (NPP). According to this theory, governance unfolds through a three-step process: operationalization, normalization, and regulation. Together, these constitute the formal institutional foundation of Party-state rule. The NPP framework elucidates the systemic proliferation of corruption as an inherent byproduct of this mode of governance, the role of the Party’s disciplinary apparatus as a self-correcting mechanism to mitigate its adverse effects, and the evolving dynamics between institutions and leadership that shape politicking and power struggles within the Politburo.

Chapter 1 sets the stage by comparing leadership elections in the two major UK parties following the Brexit referendum. While Conservative members of parliament acted swiftly to replace their leader, Labour was unable to follow suit, leading to an unprecedented internal crisis. These divergent paths, Kernell argues, can best be explained by attention to party rules. After briefly extending the comparison to discuss party rules in several other countries, Chapter 1 summarizes the book’s core arguments and the formal model, introduces the evidence, and provides a roadmap for the rest of the book.
