Verfassungsrechtliche Aspekte des Völkerrechts, einschließlich der Integration völkerrechtlicher Normen in nationale Verfassungsordnungen, Vertragsabschlussbefugnisse, völkerrechtliche Verpflichtungen und verfassungsrechtliche Grenzen internationaler Bindungen. Umfasst die Schnittstelle zwischen nationalem Verfassungsrecht und völkerrechtlichen Verpflichtungen.
The arrest and transfer of Rodrigo Duterte to the ICC was certainly good news for the heavily beleaguered Court. But the price of getting Duterte could be considerable. The manifest entanglement with Philippine politics is likely to harden Southeast Asian skepticism towards international criminal justice. Existing fears of external politicization are enhanced with a scenario of internal political turmoil, reinforcing Southeast Asian hesitation toward the ICC.
As the EU steps up its efforts to fund the defence of Europe, Hungary sticks to its policy of undermining those efforts whenever it can. Given that a Member State cannot be expelled from the EU, the Member States should simultaneously withdraw from the EU Treaties under Article 50 TEU and concurrently sign up to new EU Treaties without Hungary. Only this way could the EU effectively stand up to Russia, introduce important Treaty changes, and finally overcome tolerating Putin’s allies within the EU. Perhaps the Hungarian people would eventually join as well.
In a case that has received global attention and reproach, Mahmoud Khalil, a lawful permanent resident of the United States and recent graduate of Columbia University (another target of the Trump administration’s ire), was arrested on 8 March by Immigration and Customs Enforcement agents in front of his apartment in New York and subsequently transferred to a detention facility in Louisiana. In this blog post, my aim is to show that the case of Mr. Khalil implicates perhaps the most sacrosanct of American constitutional rights: free speech.
In this blog post, we document and analyse the numerous apparent breaches of international law that have occurred within the first six weeks of the 2025 Trump administration. What began as an informal discussion at the Lauterpacht Centre for International Law has evolved into this analytical overview. We believe this documentation serves both academic purposes and potentially supports future legal proceedings. While defenders of these actions will undoubtedly offer justifications for what we identify as clear breaches of international law, our analysis aims to provide an assessment based on established international legal principles.
Observance of international law is more important than ever in the current situation in order to maintain and restore world peace. This is especially true for Germany. We call for compliance with Germany’s obligations under international law. Especially at a time when international law is being broken by powerful states, we urgently appeal to decision-makers at federal and state levels not to jeopardize Germany’s commitment to international law.
Ende des letzten Jahres veröffentlichte die Europäische Kommission eine Mitteilung über die Abwehr hybrider Bedrohungen infolge des Einsatzes von „Migration als Waffe“. Migration werde als Taktik hybrider Kriegsführung missbraucht, lautet das Hauptargument der Kommission zur Rechtfertigung einer strengen Grenzpolitik, die das individuelle Asylrecht stark einschränken bzw. beseitigen kann, indem Pushback-Praktiken unter Umständen als legitim betrachtet werden können. Die Mitteilung der Kommission gibt in zweierlei Hinsicht Anlass zur Sorge. Zum einen lassen sich Bedenken mit Blick auf das Asylrecht formulieren, zum anderen – und hier steht die eigentliche Debatte noch aus – im Hinblick auf das Menschlichkeitsverbrechen des Verschwindenlassens.
Trump’s plans to impose "reciprocal" tariffs, announced in a Memorandum of 13 February, fundamentally contradict the existing rules of the world trade order, in particular the USA's tariff obligations and the principle of providing the same benefits to all imports and exports – known as the most-favoured nation (MFN) treatment. The absence of a bolder protest against this flagrant disregard of the law might be due to a shared understanding that the existing rules-based international economic order is in a deplorable state. The crucial question, therefore, is whether we should quietly accept its final abolition by someone with the power to do so, or rather set about repairing it. Now, tariffs may be a very mundane matter. But what is at stake here is the more general and fundamental question of international law today: how do we deal with rules that were created in better times and are now in danger of disintegrating?
On Thursday, 13 February 2025, a federal criminal court in Buenos Aires, Argentina, took a significant step toward international criminal accountability by issuing arrests warrants for Senior General Min Aung Hlaing and 24 other Myanmar military officials. This marks the first public arrest warrants to be issued against the Myanmar military in a universal jurisdiction case. This legal development represents a rare moment of hope for the roughly one million Rohingya forced to live in refugee camps in Bangladesh.
Der designierte Bundeskanzler Friedrich Merz hat laut Medienberichten in einem Telefongespräch am Wahlabend gegenüber dem israelischen Premierminister Netanjahu eine Einladung nach Deutschland in Aussicht gestellt. Für den Fall eines Deutschlandbesuchs, so Merz auf einer Pressekonferenz nach der Wahl, habe er Netanjahu „Mittel und Wege“ zugesagt, dass „er Deutschland besuchen kann und auch wieder verlassen kann, ohne dass er in Deutschland festgenommen worden ist.“ Sollte diese Einladung tatsächlich erfolgen, so würde die neue Bundesregierung damit jedoch in einen Konflikt mit dem Internationalen Strafgerichtshof (IStGH) geraten und außerdem einen innerstaatlichen Gewaltenteilungskonflikt hervorrufen.
When does sharing information become an act of disloyalty to the state? Three bills advancing through Israel’s Knesset aim to answer this question decisively: any cooperation with international justice mechanisms, particularly the International Criminal Court (ICC), would constitute a betrayal of the state punishable by up to life imprisonment. This legislative package marks a dramatic shift from merely opposing international criminal jurisdiction to criminalizing the very act of documentation and information-sharing about potential human rights violations. For Israeli scholars researching international humanitarian law, the message is clear: our academic work could become a criminal offense if it finds its way to international courts.
