Territorial Concessions to the Aggressor
How can Russia’s war of aggression against Ukraine be brought to an end? With recent proposals by the Trump transition team, a possible peace treaty with Ukraine and Russia is gaining renewed attention. Gregory Fox predicts that “territorial transfers […] would likely be at the heart of any agreement”. The rule on coerced treaties (Art. 52 VCLT) poses a major legal obstacle to territorial concessions to an aggressor state. Under that rule, a treaty is void if its conclusion has been procured by an unlawful threat or use of force. That notwithstanding, a treaty invalid under Art. 52 VCLT can be validated by the UN Security Council (UNSC), a solution that is also compatible with jus cogens. Continue reading >>

When Words Really Matter
It has been over 900 days since Russia launched its so-called ‘three-day crusade’ to capture Kyiv. The way we talk about Russia’s invasion of Ukraine has far-reaching implications, not only for public perception but also for international policy and accountability. How we label this conflict—whether we call it the ‘war in Ukraine’ or ‘Russia’s war against Ukraine’—influences how we understand responsibility, justice, and the path to peace. Continue reading >>

Wartime Constitutionalism and the Politics of Constitutional Review in Ukraine
On 18 July 2024, Ukraine’s Constitutional Court issued a decision concerning the rights of the accused in criminal proceedings under martial law. The extension of detention, the Court ruled, can only be issued based on a reasoned court decision—this applies even in times of war. In this blogpost, we examine how the war has influenced the ways in which various actors engage with constitutional complaints, before discussing the Constitutional Court's recent decision on Article 615.6 of the Criminal Procedure Code. We argue that this ruling exemplifies how the Constitutional Court can maintain the relevance and practical significance of its decision-making in wartime. Continue reading >>

Could Hungary be suspended from Schengen?
In early July, the Orbán government announced that it would extend a program that grants third country nationals simplified access and stay to work in Hungary to Russian and Belarussian nationals. This blog maps the ways in which Hungary’s policy might undermine the security of the Schengen area and surveys the tools Member States and EU institutions have at their disposal to counter it. Should the Hungarian government fail to dispel the concerns raised by its extension of the national card system, these mechanisms should be activated to safeguard the security of the Schengen area.

Why the International Criminal Court’s Jurisdiction Doctrinally Attaches to Israeli and Russian Nationals
As the storm of ICC Chief Prosecutor Karim Khan’s request for arrest warrants loomed and landed on Israeli Prime Minister Netanyahu and his Defence Minister Yoav Gallant, ardent supporters of Israel within the U.S. and U.K. governments and beyond appear to have seized upon a jurisdictional objection. U.S. Secretary of State Antony Blinken is reported as saying that the “ICC has no jurisdiction over this matter.” The U.K. Foreign Secretary David Cameron is reported to have said the same thing. There is a basic flaw, though, in the treaty-based objection to the ICC jurisdiction as has been made. It ignores the nature of the mandate of international criminal tribunals as mechanisms for the effective preservation of the basic fabric of the international order. Continue reading >>01 July 2024
Ukraine, the Netherlands and 26 Third States Without Russia Before the ECtHR
The hearing in the case of Ukraine, the Netherlands v Russia lasted four hours and twenty-five minutes. more than double than an “ordinary” Grand Chamber hearing. These four hours and twenty-five minutes are an important milestone in what is undoubtedly one of the most important set of cases in the history of European Convention on Human Rights. They cover more than ten years of Russian activities in Eastern Ukraine, including the open war of aggression since February 2022. The number of third parties involved in the proceedings likewise renders the case extraordinary. Continue reading >>

Die Verfassung der Sanktionspolitik
Das Magazin MONITOR berichtet in einem Beitrag von heute, wie diverse deutsche Firmen legale, also nicht-sanktionierte Korridore in den Russland-Sanktionen nutzen, um so Regionen wie Mariupol (unter übrigens enormen sanktionsrechtlichen und völkerrechtlichen Risiken) mit wichtigen Baustoffen zu beliefern oder beliefern zu lassen. In den sozialen Medien und unter Politikern ist sehr schnell, nämlich noch vor der eigentlichen Ausstrahlung der MONITOR-Sendung am heutigen Donnerstag, breite Empörung darüber entstanden, dass hier offenbar eines der wichtigsten Kriegsziele Russlands im wahrsten Sinne des Wortes mit deutscher Hilfe zementiert wird. Die massive Empörung über die Geschäfte ist nachvollziehbar, die allgemeine Verwunderung darüber, dass hier offenbar eine Sanktionslücke klafft, nicht. Continue reading >>27 February 2024
The EU’s Eastern Border and Inconvenient Truths
The Russian invasion of Ukraine in February 2022, alongside with the EU’s confrontation with Russia’s ally Belarus, however, has deeply impacted the securitisation of migration within the EU. Highly politicised conflict-related securitisation narratives have rarely found their way so swiftly into Member States’ domestic migration and asylum laws, leading to open and far-reaching violations of EU and international human rights law. Hardly ever before have ill-defined concepts and indiscriminate assumptions been so broadly accepted and used to shift from an individual-focused approach to blanket measures stigmatising, dehumanising and excluding entire groups. And rarely before have radical changes of this kind received so little criticism - a deeply unsettling and dangerous trend. Continue reading >>
