The Paris-based Association of Accidental Americans (AAA) said it has today filed a "request for enforcement" with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens), in which it said it is "demanding an immediate halt to the automatic transfer of European citizens’ personal data to the United States," as part of the Dutch government's compliance with the U.S. tax evasion-prevention law known as FATCA.

Lawyers and campaigners against the American tax evasion law known as FATCA say that last week's European Court of Justice (CJEU) ruling, which struck down the main mechanism used by the EU to protect the personal data of EU citizens when it's transferred to the U.S., represents a potential "game changer" – and could force Europe's courts to revisit the way FATCA compels Europe's banks and financial institutions to pass information on their U.S. citizen and Green Card-holding account-holders to the U.S. 

Correspondence and other documents having to do with the way the U.S. tax evasion-prevention law known as FATCA was agreed upon, and is now enforced by EU governments – along with similar materials having to do with the OECD’s more recent automatic exchange of information (AEOI) regime known as the Common Reporting Standard – have been published by a campaigning lawyer with London’s Mishcon de Reya law firm.
