A “One-Way Ratchet”?

On Wednesday, November 5, 2025, the U.S. Supreme Court heard one of the most anticipated oral arguments in recent times. In Learning Resources v. Trump and Trump v. V.O.S. Selections, Inc., the Court is examining the legality of President Trump’s use of emergency powers to impose sweeping tariffs. The case lies at the intersection of two powerful, and potentially conflicting, trends in the Court’s recent jurisprudence: on the one hand, efforts to constrain delegations of power to the executive; on the other, a recurring embrace of expansive presidential authority. Each path carries significant risks for the broader balance of powers in the U.S. constitutional system. Continue reading >>

Umbau in den Staaten

Seit dem Amtsantritt der neuen US-Regierung unter dem 47. US-Präsidenten Donald Trump erfährt die Wissenschaftsfreiheit und das Recht der Forschungsförderung in Nordamerika viel Aufmerksamkeit in Deutschland. Mit Erstaunen, teils mit Entsetzen, verfolgen die einschlägigen Wissenschaftsorganisationen, wie die Bundesregierung Forschungsgrants eingefroren hat und weitreichende Änderungen in Hochschulorganisation und Lehre fordert. Was in den Diskussionen um die einzelnen Maßnahmen des Bundes gegenüber Universitäten aber leicht aus dem Blick gerät, ist, was sich in den USA auf der Ebene der Bundesstaaten abspielt.

The Logic of Domestic Military Deployments

With all the outlandish legal arguments the Trump administration has deployed in the nine months since Inauguration Day, it has been genuinely puzzling that the president hasn’t yet invoked the Insurrection Act. Previously undisclosed facts revealed during the Newsom v. Trump bench trial, however, shed light both on how the motivations for these military deployments are being internalized by the military establishment and why there is not yet demand for invoking provisions of the Insurrection Act.

Trump’s Manufactured Emergencies

The Trump administration’s actions in Washington D.C. represent the continuation of interconnected political and rhetorical tactics that the president has used since his second inauguration that we should expect to see again and again – using misleading or downright fabricated information as the basis for declaring an emergency, relying on the fabricated emergency to invoke emergency legal authorities, and then relying on those authorities to take actions that exceed even the broad powers that such emergencies confer under the law. Looking ahead, we can expect the administration to run this same playbook in additional, predictable ways. Continue reading >>

Tat und Territorium

Am 23. Juli 2025 wurde Sebastian Hotz alias „El Hotzo“ vom Amtsgericht Berlin-Tiergarten vom Vorwurf der Billigung von Straftaten, § 140 StGB, freigesprochen. Die Bedeutung des Falls erschöpft sich nicht in der bekannten Streitfrage um das Verhältnis von grundrechtlicher Meinungsfreiheit und strafrechtlichen Meinungsäußerungsdelikten. Tatsächlich wirft er noch ein anders gelagertes Problem auf: Kann das deutsche Strafrecht die Billigung einer Tat erfassen, die im Ausland begangen wurde? Dass § 140 StGB auch solche Anlasstaten erfassen kann, gilt als gefestigt. Diese Auslegung bricht aber mit dem historischen Sinn der Norm und weitet das Strafrecht in Bereiche aus, in denen es nichts zu suchen hat. Continue reading >>

An Elusive Touchdown with a Political Football

On July 19, Congress voted to revoke funding from the Corporation for Public Broadcasting – something it has not done in the 60 years since its creation. In countries with strong public media traditions, this may seem astonishing: Why would Congress defund NPR and PBS after already having appropriated the money? And what does this mean for the First Amendment? To answer these questions, we must consider the peculiar history of public broadcasting in the United States. Continue reading >>

The Nondelegation Case Against Trump’s New Travel Ban

Donald Trump has imposed the second travel ban of his presidential history. Despite the enormous harm it is likely to cause, many assume there is no effective way to challenge it in court. The Supreme Court's ruling in Trump v. Hawaii (2018) – addressing Trump’s first-term “Muslim ban” – probably precludes challenges based on discriminatory intent. Nonetheless, there is an alternative path to striking down the new travel ban: the nondelegation doctrine. This doctrine sets limits to Congress’s delegation of legislative authority to the executive. Continue reading >>
