Discussants Professor Peter-Tobias Stoll, Professor Duncan French, and Dr Oisin Suttle were asked at the workshop held on 22–23 June 2018 at the World Trade Institute, Bern, Switzerland, to offer an overall assessment of the notion and potentially emerging legal principle of Common Concern of Humankind in international law. Their authorised interventions are transcribed below. They raise pertinent questions as to the novelty of the concept, the thresholds discussed, the relationship to public goods, the feasibility, and methodological implications a prospective principle of Common Concern of Humankind poses. They are encouraging and cautioning at the same time, pointing to conceptual innovation and weaknesses in the chapters of this volume, and offer guidance for further research on the topic.
