Bull Bitcoin has filed a petition with the Conseil d’État, France’s highest administrative court, seeking to challenge France’s implementation of the EU’s DAC8 crypto reporting rules. According to the source material, DAC8 took effect on January 1, 2026, requiring crypto asset service providers to collect customer and transaction data, report it to French tax authorities, and support automatic information exchange with other participating jurisdictions.
Automatic reporting is at the center of the dispute
Bull Bitcoin argues that the framework goes beyond ordinary tax reporting by creating a broad repository of personal information, including user identities, home addresses, and records of crypto activity. The company says the earlier system limited data sharing to cases involving lawful requests from authorities or detected suspicious activity. Under DAC8, by contrast, reporting becomes automatic, so data can be transferred even when no wrongdoing has been identified.
That shift, the company says, expands the circulation of sensitive financial information and raises security concerns. The source notes that Bull Bitcoin warned centralized databases containing identity details, residential addresses, and crypto transaction records could become attractive targets for cybercriminals and organized crime groups. It also referenced a recent increase in kidnappings and violent attacks targeting crypto holders in some countries, arguing that misuse of large financial datasets could intensify those risks.
Company seeks annulment of France’s implementation decision
Bull Bitcoin is asking for the decision implementing DAC8 in France to be annulled. The company has also said it is prepared to take the matter to the Court of Justice of the European Union or France’s Constitutional Council if needed. Bull Bitcoin is described in the source as a provider of Bitcoin-focused trading and custody services.
Comparable legal pushback has surfaced in the US
This is not the first court challenge by the crypto industry against reporting mandates. The source says industry representatives in the United States have also sued over Internal Revenue Service broker reporting rules and transaction disclosure requirements, with cases heard in several courts including the US District Court for the Northern District of Texas. Those suits argued the rules violated the Fourth and Fifth Amendments and the Administrative Procedure Act. Courts have generally not fully repealed tax reporting regulations, but they have pressed regulators to clarify definitions or narrow the scope of their rules.
Separately, Thai authorities issued an arrest warrant for Chinese businessman Wang Yicheng, alleging that he played a central role in an illegal crypto mining network that reportedly consumed about $28 million worth of electricity without authorization.
