An Austrian non-profit that successfully challenged two seminal, transatlantic data transfer agreements says that a successor deal recently announced by authorities is unlikely to hold up in Europe’s highest court.

Last week, European Commission president Ursula von der Leyen and U.S. President Joe Biden announced they had concluded a preliminary deal on a new framework that would offer companies like Meta and Google a robust legal basis to transfer the personal data of EU users to the U.S. According to the European Commission, these transatlantic data flows fuel €900 billion in cross-border commerce annually.
