GLaw-Net Seminar with Lucas Carlos Lima

On 23 November 2022, the Glaw-Net held the hybrid seminar featuring Lucas Carlos Lima , Professor of International Law at the Faculty of Law of the University Federal of Minas Gerais, Brazil. During the seminar, Professor Lima presented his paper "Is the IACtHR advancing the notion of regional jus cogens or a certain regional approach to jus cogens in its case law?" Professor Jure Vidmar acted as a discussant. The presentation revolved around the regional approach of the Inter-American Court of Human Rights (IACtHR) to jus cogens in South America. Although Article 53 of Vienna Convention on the Law of Treaties (VCLT) indicates certain norms as peremptory norms jus cogens , the origin of these norms remains ambiguous. This uncertainty has encouraged scholarly debate on the nature of these norms. The interest in this topic was recently sparked by the Draft Conclusions on Peremptory Norms of General International Law by the International Law Commission (ILC). The conclusions preclude different interpretations and applications of jus cogens norms in the regional context, with most states reluctant to promote regional diversity as well.
