Trade with the Settlements: How EU Law Points the Way Out of the Deadlock

August 4, 2026

Nicolas Angelet

The International Court of Justice’s Advisory Opinion of 2024 on Legal consequences arising from the policies and practices of Israel in the Occupied Palestinian Terrritory, including East Jerusalem has prompted many scholarly comments on third states’ obligations to react to violations of international law by Israel in the Occupied Palestinian Territory (OPT) (notably here and here). Much has been written also on the rather passive stand of the European Union (EU) in this respect (notably here and here), which manifested itself again this summer when the EU Foreign Affairs Council proved unable to take measures with respect to the Israeli settlements in the OPT. Less attention has been given to how this deadlock, and the EU’s posture towards Israel more generally, relate to the legal intricacies of the EU’s decision-making process as well as to its foundational principles. This post argues that banning trade with the settlements is a matter of the Union’s living up to its foundational principles, which include respect for international law and the rule of law. It…

Salvador Leyva Morelos-Zaragoza

In April 2026, the Committee on Enforced Disappearances (CED) adopted a resolution under Article 34 of the International Convention for the Protection of All Persons from Enforced Disappearance (hereinafter “the Convention”) and urgently brought the matter before the UN General Assembly.

Two Weeks in Review: 13—24 July 2026

July 26, 2026

Sebastian von Massow

The last fortnight has seen commentators focus primarily on conflict, climate, and immigration. A mini-symposium has ranged over a number of legal questions raised by a potential Russia-Ukraine peace treaty: from VCLT rules on treaty validity and security guarantees, to free economic zones and the question of the reconstruction of Ukraine through seized assets of the Russian Central…

Red lines in a grey zone: the validity of a Russia-Ukraine peace treaty under international law

July 13, 2026

Asli Ozcelik

While peace still appears remote, the prospect of a negotiated end to the war in Ukraine raises difficult questions concerning the international law governing inter-state peace treaties. The unlawfulness of Russia’s use of force and the peace plans proposed to date point to issues of validity, particularly under Articles 46, 52 and 53 of the Vienna Convention…

In the four years since Russia’s 2022 invasion of Ukraine, the prospects of a negotiated peace settlement have waxed but mostly waned. But the possibility of an agreement has been an ongoing focus for international lawyers. This is primarily because Russia has demanded territorial concessions from Ukraine that appear at odds with…

Daphné Richemond-Barak

After days of speculation, the clouds have begun to clear over Palestine's strategy at the ICC. Ever since the Security Council rejected a draft resolution on December 30, 2014 designed to upgrade Palestine's status to full Member State of the UN and imposing a 12-month deadline on a negotiated solution to the Israeli-Palestinian conflict, the media overwhelmingly…

Editorial: The Case for a Kinder, Gentler Brexit

February 6, 2017

Joseph Weiler

Of course, we know better than to be shooting at each other; but the post-23 June relationship between the United Kingdom and the European Union is woefully bellicose, and increasingly so. In tone and mood, diplomatic niceties are barely maintained and in content positions seem to be hardening. I am mostly concerned with attitudes and positions of and…

Marko Milanovic

If, dear readers, you have any doubts that the parliamentary politics of Brexit have emerged from the fever dream of some demented game theorist, I would just ask you to take a very quick look at the events of last week. In their second meaningful vote on Theresa May's Brexit deal, British MPs voted it down by…
