Governance is not natural justice. It is an intervention that must be limited. In the real world, most disasters do not occur where no one governs. They occur where governance still exists, yet has lost its repair capability. Institutions still run, reports are still produced, but the problem does not disappear—it becomes stabilized and rationalized. "Ungovernable Domains: Governance Boundaries and Governance Overreach" is the canonical text on Irreversibility Threshold Theory . Ng Tick Kee (吴明序然) challenges the civilizational assumption that "governance is always better than not governing." This book asks the dangerous question: Under what conditions does continuing governance become an act of dereliction? Core Adjudications: The Irreversibility Threshold: Identify the exact point where a system undergoes a phase transition. After this point, any governance action no longer repairs; it magnifies harm. Governance Overreach: Overreach is not about strictness; it is about continuing to govern after validity conditions have ended. When persistence becomes the only source of legitimacy, governance turns into a domination structure. The Disappearance of the Object: Why adding more management to a system where the "governance object" (responsibility bearer) has disintegrated is futile. Termination as Responsibility: Stopping is not failure. When governance becomes structural violence, termination is the highest form of responsibility. This is not a book for those seeking hope. It is for those seeking judgment. Written for leaders willing to bear the weight of "stopping," this book provides the structural logic to adjudicate when a system has become ungovernable and why exit is the only rational governance act remaining.
