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
In Europe, we’re all in the same boat, but we tend to row in opposite directions. But isn’t that what society is?

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

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
Quote from our newest blogpost by Costanza Margiotta: “By rendering the axiological dimension of the Treaties justiciable, it confers legal relevance on the form of social coexistence embodied in Article 2 TEU.”

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...
Quote from our newest blogpost by Ferdinand Weber: “The latest efforts to judge and write the EU into a new era of constitutionalism reach a natural limit: primary law’s other basic norms.”

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...
European society can therefore be understood as a form of structured interaction.

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
