Can companies continue transferring personal data from the EU to the US in the foreseeable future? USSC Trump v. Slaughter, made that prospect less likely. On @verfassungsblog.de, I explore this fascinating intersection of EU data protection law and U.S. constitutional law. shorturl.at/uN1rX

At this year's Academy of EU at the EUI, the concept of European society was heavily debated. CHIARA RIMKUS reflects on these discussions and explains what they mean for the future direction of EU legal scholarship. verfassungsblog.de/debating-eur... @mpil.de

Article 2 TEU contains the operative legal category of solidarity. Yet, as TERESA VIOLANTE critically explains, this concept has not entered the CJEU's reasoning. verfassungsblog.de/whose-europe... @mpil.de

Scholarship on European society fixates on public law. But what binds people together are the private, cross-border relations between them. MARLENE TIEDE shows how EU private international law knits diverse national laws into one legal community. verfassungsblog.de/private-inte... @mpil.de

Is the justiciability of Article 2 TEU an act of self-empowerment by the Court? LUKE DIMITRIOS SPIEKER argues that its activation is rather the result of a collective interpretation by the European society. verfassungsblog.de/a-european-s... @mpil.de

EU digital regulation shapes European society from both an institutional and a practice-oriented perspective. KATARZYNA ŁAKOMIEC identifies the obstacles to building shared European values in the digital sphere. verfassungsblog.de/european-soc... @mpil.de

Our symposium on European society turns to the question: does Commission v Hungary constitutionalise European society? Not yet, argues COSTANZA MARGIOTTA, but it creates the conditions for European society to become constitutionally significant. verfassungsblog.de/from-values-... @mpil.de

Long before the CJEU, “European society” was already an idea rooted in 18th-century interstate law. FERDINAND WEBER traces this history to ask where today’s constitutionalist reading of Article 2 TEU meets its limits. verfassungsblog.de/lines-and-li...

Commission v Hungary presents European society as a source of legitimacy for EU values. Through a Habermasian lens, FRANCA MARIA FEISEL argues that the Court's appeal to European society as a source of authority is difficult to reconcile with democratic legitimacy. buff.ly/UiS8mt4 @mpil.de

Mutual trust is not merely a technical principle governing inter-state recognition; it is also a social mechanism. JASPER SIEGERT argues that Commission v Hungary advances the preconditions on which mutual trust depends. verfassungsblog.de/a-society-of...

Gender equality is a value in Art. 2 TEU – but it is nearly absent in the CJEU’s Commission v Hungary. @silviasteininger.bsky.social & SEONA KIM apply a feminist re-reading to the Court's arguments and ask what a non-patriarchal European society would actually require. buff.ly/sn5U9qP @mpil.de

Poland's post-2023 government never submitted its promised media reform to parliament. MARCIN BARAŃSKI warns how quickly new governments abandon the reforms they promised. verfassungsblog.de/the-burden-o...

For the fifth consecutive election, the winning party has secured a two-thirds majority in Hungarian parliament. BEÁTA BAKÓ argues the magic of that supermajority was always a lie: it never guaranteed compromise. verfassungsblog.de/the-big-lie-...

Poland's rule of law recovery remains largely incomplete – and Hungary might soon walk a similar path. ADAM BODNAR argues that rebuilding institutions is not enough: accountability requires committed prosecutors and patient voters. verfassungsblog.de/polish-lesso...

Transitional justice scholarship was built for dictatorships – not for hybrid regimes like Hungary or Poland. ANDRÁS JAKAB identifies blind spots in the current discourse and outlines what a post-hybrid transitional justice framework would need to look like. verfassungsblog.de/transitional...

The European Court of Justice declared Hungary's 2021 anti-LGBTIQ legislation incompatible with EU values — and transforms Article 2 TEU into a justiciable red line for Member States. @dimitrispieker.bsky.social maps the doctrinal consequences in a new FAQ (in German): www.mpg.de/26406160/eug...

Does lawbreaking always undermine the law against war or can it sometimes support it? @chr-marxsen.bsky.social's book „Shades of Illegality in the Law Against War" emerges from the #MPIL SHADES project and argues: it depends on the type of breach. global.oup.com/academic/pro...

Rethinking EU defence: if the law already allows closer cooperation, what is really holding the EU back? @moserc.bsky.social argues that political will, not legal gaps, is the main obstacle to a more integrated EU defence posture. Read more: kluwerlawonline.com/api/Product/... #EUdefence
