Publication: The Transformation of International Investment Law and Its Principles by Dr Güneş Ünüvar

The Luxembourg Centre for European Law (LCEL) is pleased to announce the publication of The Transformation of International Investment Law and Its Principles: Indirect Expropriation and Fair and Equitable Treatment, a new monograph by Dr Güneş Ünüvar, Postdoctoral Researcher at the LCEL, published by Springer Nature.

This monograph offers a comprehensive examination of how international investment law has evolved through the interpretation and application of two foundational protection standards: Fair and Equitable Treatment (FET) and indirect expropriation. It explores how arbitral tribunals have shaped these principles in practice, and how arbitral jurisprudence, in turn, has influenced the drafting and recalibration of investment treaties over time.

The book includes an in-depth analysis of the European Union’s “new generation” investment agreements, including the CETA, EU–Singapore Investment Protection Agreement, EU–Vietnam Investment Protection Agreement, as well as the recently concluded EU–Chile and EU–Mexico agreements. The study situates these texts within the broader landscape of contemporary treaty-making, offering a detailed comparison with other comprehensive economic agreements and mega-regionals, such as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). This comparative perspective illuminates broader global trends towards greater clarity, specificity, and balance in investment treaty design, as states seek to reconcile investor protection with regulatory autonomy and public policy objectives.

The publication is closely linked to Dr Ünüvar’s research at LCEL, which focuses on the evolving interface between international economic law and global governance. His work examines how investment protection frameworks adapt to shifting political and economic realities. By bridging treaty practice and arbitral jurisprudence, this monograph provides valuable insights for scholars, practitioners, students, and policymakers interested in the future of the investment regime.

The book is available in both eBook and hardcopy formats from Springer Nature.
