Ulf Linderfalk



Ulf Linderfalk is Professor of International Law in the Faculty of Law, Lund University, which he joined in 2001. Linderfalk is a general international lawyer, who takes a special interest in questions relating to international legal structure. His research has examined issues arising from phenomena such as normative conflict, legal hierarchy, treaty interpretation, special regimes, cross-fertilisation among such regimes, legal principles, legal discretion, balancing, and conceptual terms. It combines analytical skills and a broad knowledge of international law with a keen interest in issues of theory including, in particular, language theory and pragmatics.

Linderfalk’s publications include three monographs – the two in English are ‘On the Interpretation of Treaties’ (Springer, 2007), and ‘Understanding Jus Cogens in International Law and International Legal Discourse’ (Edward Elgar, 2019, in press) – two textbooks (both of which are available in updated second editions); two co-edited volumes; and a total of 30 articles in high-ranking peer-reviewed international law journals, including some of the most prestigious such as the European Journal of International Law, the International and Comparative Law Quarterly, and Zeitschrift für ausländisches öffentliches Recht und Völkerrrecht. Linderfalk has a recognised standing in the international law research community, and he has close contacts with colleagues at several universities, organisations, and institutions throughout the world. His work is cited in leading international law textbooks, commentaries and encyclopaedias; it has been considered repeatedly by the UN International Law Commission. He was awarded, in 2017, the Nordic Tax Research Council Article Prize for best article published in the 2016 edition of the Nordic Tax Journal.

Linderfalk’s research on different aspects of international legal structure has been funded by significant research grants from, among others, the Swedish Research Council (three times), Ragnar Söderbergs stiftelse (twice), and Torsten Söderbergs stiftelse, amounting to a total of approximately SEK 18 million. This has enabled him to work closely, in particular projects, with colleagues in Lund as well as abroad, including Eric de Brabandere, Anna Nilsson, Xavier Groussot, Valentin Jeutner, Eduardo Gill Pedro and Maria Hilling. Linderfalk also brings his expertise in building, leading and administering large-scale research groups, including the group of five funded by the Ragnar Söderberg foundation, “Proportionality in the Application of International Law: In Search of Coherence” (2012-2017); and the group of three funded by the Swedish Research Council, “What’s so Special with the Special Regimes?” (2018-2021). Since 2011, Ulf Linderfalk has been the Editor-in-Chief of the leading Scandinavian international law journal, the Nordic Journal of International Law. He was a member and Vice chair of the Board of Research at the Faculty of Law, Lund University, from 2012 to 2017.
