On 14 September 2019, I gave a presentation on cosmopolitanism and extraterritoriality at the annual conference of the European Society of International Law in Athens, Greece (panel on extraterritoriality). In this post I restate the main points of my presentation. This post also serves as a wrap-up of two research projects which I have carried out over the last five years, partly under Ucall auspices, on extraterritoriality and global values. These projects involved in total seven PhD researchers, whom I would like to wholeheartedly thank for their contributions. Two of these researchers were affiliated with Ucall (Lucas Roorda and Friederycke Haijer). A monograph bringing together the various parts of the project is forthcoming in spring 2020, provisionally titled ‘Selfless Intervention. The Exercise of Jurisdiction in the Common Interest’ (under contract with Oxford University Press). As cramming the research results of a large project into one blogpost is quite impossible, I will paint with a broad brush, and make choices. I will start by defining cosmopolitanism, and go on to explain how common interest-based reasoning may be inscribed into existing principles of jurisdiction, in particular territoriality. The first part of the post will be conceptual, while the second part will be more practical and doctrinal. Lees verder →
