(De)Valuing Citizenship
Last Tuesday, the US Supreme Court released its final merits opinion of its October 2025 term. In Trump v Barbara, a razor thin 5-4 majority deemed the President’s attempt to deny American citizenship to children born on U.S soil to immigrant parents who are undocumented or present on certain visas unconstitutional. The decision is a rare and important win for immigrants and American constitutional democracy. But Barbara should not be remembered as an example of principled judicial resistance against gross executive overreach.

AI Is Eating the Book World
In 2011, Marc Andreessen, a key figure in California’s venture capital scene, coined the phrase: “Software is eating the world.” The phrase describes the spread of software into everyday life and the displacement of physical business models. This process continues in an unexpectedly literal sense: AI companies purchase used books, scan them, and dispose of them to gather input for their models. The reason for this seemingly cumbersome method is the expectation that it will fall under the fair use provision of U.S. copyright law.

The Problems with “General Purpose AI Detectability”
As AI-generated media flood our information ecosystems, detecting synthetic content has become an urgent regulatory challenge – in fact, not one challenge but many, as synthetic media breeds problems across a range of digital contexts, including deepfakes and disinformation, scamming, and content moderation. The EU's new "Code of Practice on Transparency of AI-Generated Content" – the first concrete articulation of Article 50(2) AI Act, the EU's approach to AI-content detection – gives sensible answers to several open questions and will advance the global regulatory debate.

The Politics of Provocation
A recent judgment of the European Court of Human Rights concerning a TikTok video published by a Georgian self-defined civil activist adds another layer to the Court’s increasingly messy Article 10 case law. The applicant repeatedly insulted public officials in crude and sexually explicit terms while broadcasting to a large online audience. Domestic courts imposed only a modest administrative fine, later reduced on appeal. The ECtHR did not find a violation of the applicant’s right to freedom of expression – raising several questions about the limits of legitimate political speech online.

Von Zustimmung und Widersprüchen
Am 25. Juni diskutierte der Bundestag wieder über die Organspende. In der Grundsatzdebatte ging es um die Frage, ob die aktuell geltende „Zustimmungslösung“ durch die effektivere „Widerspruchslösung“ ersetzt werden sollte. Ich analysiere diesen Streit aus ethischer Sicht und argumentiere für eine Perspektivänderung: Wir müssen uns vor Augen führen, wie die Widerspruchsregelung das Recht auf Selbstbestimmung genau verletzt – und in welchem Maße.

Europäische Lös(ch)ung?
Erstmals könnte ein Verfahren wegen eines Verstoßes gegen die Werte der Union zum Ausschluss einer europäischen Partei von der EU-Finanzierung führen. Ob die Europe of Sovereign Nations (ESN), zu der auch die AfD gehört, tatsächlich aus dem Parteienregister gelöscht werden kann, entscheidet sich nicht an politischen Mehrheiten allein, sondern an der dogmatischen Konkretisierung des Art. 2 EUV. Der EuGH hat hierfür in den vergangenen Jahren Maßstäbe entwickelt, die nun erstmals in einem solchen Verfahren praktisch relevant werden könnten.

Amid pending proceedings before the ECtHR concerning summary expulsions and arbitrary detentions, in a context marked by over 120,000 documented push-backs on the Belarusian border, the Chișinău Declaration seeks to influence the legal framework within which the Court assesses such practices. The Declaration emphasises the fundamental duty of states to protect their borders and maintain national security in the context of instrumentalisation of migration, drawing on “democracy capable of defending itself”. I argue that it is not a task for the Court to carve its decisions based on geopolitical circumstances.

Ein bundesweites Vergesellschaftungsverbot?
Die Regierungskoalition hat Anfang Juli ein „Rahmenprogramm für Aufschwung und Beschäftigung“ vorgestellt. Aus verfassungsrechtlicher Perspektive ließ viele ein zunächst unscheinbares Detail aufhorchen: In Punkt 18 des Programms heißt es: „Um den privaten Wohnungsbau nicht zu gefährden, wird durch Bundesgesetz geregelt, dass die Verstaatlichung privater Mietwohnungsbestände durch Vergesellschaftungsgesetze auf Landesebene nicht mehr möglich ist.“ Bei genauerem Hinsehen zeigt sich, dass die Pläne gleich aus mehreren Gründen verfassungswidrig sind.

The sentencing decision delivered in England on 12 June 2026 in the Palestine Action case marks one of the first prominent judicial tests of a little-noticed but constitutionally troubling provision expanded by the Counter-Terrorism and Sentencing Act 2021, under which terrorism-related consequences such as altered release arrangements, forfeiture orders and long-term notification duties can be attached to ordinary criminal convictions on the basis of a judicial finding made after conviction rather than a jury verdict.

Venezuela After the Earthquakes
On June 24, 2026, two earthquakes struck Venezuela with magnitudes of 7.2 and 7.5. As of 2 July, the official death toll has climbed past 2,295, and more than 38,600 people remain unaccounted for. Having lived through the disaster in Caracas and seeing people desperately crying for help, only reinforces our own empirical understanding of a state in decline. Democracy depends on social trust and a functioning state with administrative capacities. Within hours, what the earthquakes revealed was the extent to which those foundations have eroded in Venezuela.

European Society After Commission v Hungary
The landmark judgment in Commission v Hungary has opened a new chapter in the history of EU law. In this decision, the CJEU not only held that Article 2 TEU can be invoked as a self-standing provision in infringement proceedings but also acknowledged the existence of a European society, in which certain values prevail – a historic first. In this symposium, we aim at showing the diverse ways in which scholars from law, philosophy, and the social sciences reflect on European society, in and beyond Commission v Hungary.

This symposium brings together judges, practitioners, and scholars from the European, Inter-American, and African regional human rights systems to examine climate change as a human rights challenge, tracing shared legal questions, divergent doctrinal responses, and the growing importance of inter-judicial dialogue in shaping transnational climate justice.

Enabling Access, Fostering Innovation: Towards a Digital Knowledge Agenda in Europe
Access to knowledge and information is essential to foster innovation. In the EU, existing copyright rules pose significant barriers to research and education. Instead of promoting access to knowledge resources, copyright creates legal uncertainty for researchers and educators and enables information intermediaries to exercise strict control over the use of protected works. This edited volume proposes ways out of the copyright conundrum by rethinking copyright as an access right.
