This week I gave a course at The Hague Academy of International Law on International Law and Domestic Courts: Quantum Uncertainty. Many thanks to the Curatorium and staff of the Academy, the wonderful students, and the lovely interpreters and technicians.

And, @djag2.bsky.social - you said we *were* friends and colleagues? I very much hope we still are, even if we live so far apart.

I’ve been a low-key fan of this pod since it started - I particularly enjoy the “what everyone gets wrong about…” sub-series. Deliciously irreverent and appropriately highbrow. But for this one I have to thank the co-hosts for the shout-out. Perhaps I need to write about 2803.

Thanks to the Codification Division for inviting me to teach on the UN Regional Course in International Law for Asia and the Pacific - I had a great time debating international law issues with enthusiastic colleagues from the region. Special thanks to Carla Hoe & to Judith Violago.

I gave a talk on the UN and its sanctioning power at the International Symposium on the 80th anniversary of the United Nations in Shenzhen. Thanks to the wonderful colleagues at the Institute of International Law of the Chinese Academy of Social Sciences for the kind invitation.

With some excellent colleagues we represented the Republic of Equatorial Guinea before the International Tribunal for the Law of the Sea in the M/T Heroic Idun (No 2) case. A great team.

A wonderful - if unorthodox (pun intended) - start to the academic year: a seminar on reservations to treaties for the LLM of the University of Athens, on the margins of a long hearing at the International Tribunal for the Law of the Sea. Thanks to all for the enjoyable seminar.

With Johanna Lorenzo and Christian Walter, we shared our impressions at the concluding roundtable of the @esil-sedi.bsky.social 2025 Annual Conference in Berlin on Reconstructing Int’l Law. Chaired by Vasilka Sancin. Many thanks to Helmut Aust and Heike Krieger of @freieuniversitaet.bsky.social.

Thank you, IDS class of 2024-25. I hope you enjoyed it as much as I did - and sorry we got rained on just when y’all wanted to take a picture.

We’re now mid-way through Trinity Term! 🌞 Today, we had the fantastic opportunity to hear from Prof @atzanakopoulos.bsky.social on ‘International Law and Domestic Courts: Quantum Uncertainty’.
