Eli Lauterpacht Lecture 2025 - 'Hard Law in Times of Liquid Modernity: Treaty Law and Practice in the 21st Century' - Santiago Villalpando, Legal Advisor and Director of UNESCO

The speaker for the Eli Lauterpacht Lecture 2025 is Santiago Villalpando, Legal Advisor and Director of UNESCO.

Lecture summary: Is international law facing a decline of treaties? In recent years, several authoritative voices have pointed out certain developments which seem to indicate that States are shifting away from treaty law-making for the governance of their international relations. Taking as a starting point the sociological concept of “liquid modernity” introduced by Zygmunt Bauman, this lecture will explore how treaties, archetypes of solid and stable law-making, have reacted to an unstable global community where norms seem to be eroding and long-term commitments appear to be challenged. As the lecture will show, there is no doubt that the law and practice of treaties have evolved to adapt to a shifting international environment, but the news about the death of treaties are greatly exaggerated. 

Eventbrite Registration - in person only 

There will be a sandwich lunch at 12.30 pm in the Old Library. All lecture attendees welcome.
