Ammar Tanhan examines how TPF operates inside investor-state dispute settlement (ISDS), where it touches procedural fairness, conflicts of interest, the commodification of justice, and state sovereignty. Set against ongoing reform efforts at UNCITRAL and other institutions, the book combines theory, case law and a comparative survey of current and proposed regulation to offer practical, policy-relevant conclusions on how TPF should be governed.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTraces the financial impact of third-party funding on the volume and value of investment claims\u003c\/li\u003e\n\u003cli\u003eAnalyses conflicts of interest between funders and arbitrators — the regulatory gap most reform efforts have focused on\u003c\/li\u003e\n\u003cli\u003eCompares current and proposed TPF regulation across jurisdictions and institutions, including UNCITRAL's reform track\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCoverage\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eSeven chapters move from the modern history and mechanics of third-party funding through its financial impact on ISDS, its effect on the quality and quantity of investment claims, the ethical and legal issues it raises, and a proposed framework for balanced regulation.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAbout the Author\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAmmar Tanhan researches and writes on international arbitration and investment law, with a focus on the funding structures reshaping how investment claims are brought and litigated.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTable of Contents\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e1.
