The Essex Public International Law Lecture Series welcomes you to to the latest instalment presented by Professor Campbell McLachlan QC,Victoria University of Wellington and chaired by Dr Meagan Wong from the School of Law at the University of Essex.

About the Lecture 

What explains the persistence of the idea of international law’s systematicity in view of its decentralised nature, constantly dependent upon the shifting consent of states and the vagaries of political will? To what extent can its systemic character endure and adapt as the tectonic plates of geo-politics shift? In this lecture, Campbell McLachlan critically re-examines the evidence for the impulse to integrate the various specialised sub-fields of international legal cooperation into a coherent system: the impulse that underpins the principle of systemic integration. He does so in light of the practice of states and international tribunals, which has deepened over the last fifteen years since his research on the principle for the ILC Fragmentation Study Group in 2005. He tests the fruits of this internal analytical perspective against both an increasing scholarly critique and the external disintegrative pressures that the system currently faces––pressures that appear to challenge the very value of global cooperation under law that underpins the idea of systematicity.

About the Essex Public International Law Lecture Series

The Essex Public International Law lecture series is founded, hosted and co-chaired by Dr Meagan Wong and Dr Emily Jones based in the School of Law. This is a weekly lecture series featuring judges of international courts and tribunals, leading academics, and practitioners of international law from governmental service, international organizations, and private practice from across the globe. The series prides itself on building on two important intellectual traditions of international law: formalism and international legal practice, and international legal theory including postcolonial and feminist perspectives. 

We welcome all students, academics, practitioners and legal advisors to join us.
