A new legal analysis from Faegre Drinker Biddle & Reath LLP examines how the US Supreme Court's decision in Trump v. Slaughter could affect the flow of personal data between the European Union and the United States, and the durability of the EU-US Data Privacy Framework that currently underpins those transfers.

The analysis, published by the firm under the title "Trump v. Slaughter: Implications of the US Supreme Court's Ruling for EU-US Data Transfers and the Data Privacy Framework," connects the Court's ruling to one of the most consequential questions in transatlantic privacy practice: whether personal data of EU residents can continue to move lawfully to the United States.

The EU-US Data Privacy Framework is the successor to two earlier transfer mechanisms, the Safe Harbor and the EU-US Privacy Shield, both of which the Court of Justice of the European Union struck down — in Schrems (2015) and Schrems II (2020) respectively — on grounds that US government surveillance practices did not provide EU data subjects with protections equivalent to those guaranteed under EU law. The Framework, adopted in 2023, was designed to close the perceived gaps identified by the CJEU, in part through a US Executive Order introducing new safeguards on signals intelligence collection and a redress mechanism for affected individuals.

According to the Faegre Drinker analysis, the Supreme Court's holding in Trump v. Slaughter raises fresh questions about the stability of that settlement. The firm's piece assesses the ruling's implications both for the legal architecture supporting the Framework and for the practical decisions companies must make when transferring EU personal data to the United States.

For practitioners, the stakes are familiar but significant. Thousands of companies on both sides of the Atlantic rely on the Data Privacy Framework as a lawful basis for transfers under the EU General Data Protection Regulation. Any development that weakens the Framework's foundations — whether a change in US administrative practice, a shift in the redress mechanism's effectiveness, or a judicial ruling bearing on the underlying US legal instruments — forces privacy counsel to reassess transfer strategies, including the fallback use of Standard Contractual Clauses and transfer impact assessments.

The analysis arrives at a moment of heightened scrutiny for transatlantic data flows. Privacy campaigners, including the litigant behind the original Schrems challenges, have signaled continued intent to test the Framework's adequacy before the CJEU. Meanwhile, US courts and regulators continue to shape the domestic legal environment that EU decision-makers weigh when evaluating whether American law delivers essentially equivalent protection.

The Faegre Drinker piece situates Trump v. Slaughter within that broader context, examining what the Supreme Court's reasoning means for the specific US commitments — on surveillance limits, independent redress, and judicial oversight — that the European Commission relied upon when adopting its adequacy decision for the Framework.
