‘Few would deny today that general international law is pivotal in the everyday practice of investor-state dispute settlement. Matters of treaty interpretation, attribution of conduct or issues pertaining to remedies – among many others – have become the bread and butter of international investment law. This excellent volume, however, changes perspective. It assesses the actual and potential impact of international investment law practice on general international law: How does it shape, how do its investment law’s actors influence general international law? Such approach is fascinating not least because no other field of international law contributes as much to adjudicatory practice in terms of numbers of awards and decisions. The contributions in Radiating Effects intriguingly explore an understudied but rich topic, looking specifically at the law of treaties, international responsibility and dispute resolution. This book is a must-read not only for those interested in investment law and arbitration but for anybody who practices, studies or teaches international law.’
