This article was presented at the conference “A Nordic Approach to International Law?” held in Oslo in August 2015 as a part of a panel on “Nordic Judges of International Courts”. It studies the Nordic judges of the Permanent Court of International Justice and its successor the International Court of Justice with a view to assessing whether common traits in their voting practice exist that might support the idea of ‘a Nordic approach to international law’. In light of the relatively limited available material, however, the article has no grander aspiration than to describe the engagement of Nordic judges with the World Court and to provide examples of their respective approaches to treaty interpretation.
