This episode accompanies the launching of a new rubric in the European Journal of International Law – Legal/Illegal. The first installment of Legal/Illegal, which appears in issue 32(4), focuses on the question whether the use of force by a state to recover a territory that has been occupied for many years may be considered a lawful act of self-defence. In the Podcast, Michal Saliternik interviews the authors of this section: Tom Ruys and Felipe Rodriguez Silvestre on the illegal side, and Dapo Akande and Antonios Tzanakopoulos on the legal side. Beginning with the second Nagorno-Karabakh war, passing through the conflicts over the Falkland Islands, the Golan Heights, Northern Cyprus, and the Chagos Islands, and concluding with the Russian occupation of Ukrainian territories, they discuss the compatibility of forcible recovery of an occupied territory with the self-defence immediacy and necessity requirements as well as with the obligation to settle territorial disputes through peaceful means. They also discuss questions of justice and fairness, both towards the conflicting states and towards the inhabitants of the occupied territory.
