Who counts as a 'controller' under the GDPR when a Member State's official journal republishes personal data drawn from company filings?
In Case C-231/22, État belge v Autorité de protection des données, the Court of Justice (Third Chamber), judgment of 11 January 2024, held that the body operating a Member State's official journal is a 'controller' within the meaning of Article 4(7) GDPR for the personal data contained in company documents it is legally required to publish as they stand — even where it neither determines the content of those documents nor verifies it before publication.

Why Lawstronaut for EU legal research
EU legal information is spread across the Official Journal, legislation databases, the institutions, the Court of Justice, and dozens of specialised agencies and regulators. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the legal source directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About European Union legal coverage
The European Union is a supranational legal order of its own kind. Its primary law is set out in the founding Treaties, while secondary law takes the form of regulations, directives, decisions, and delegated and implementing acts. Binding legislation and consolidated texts are published in the Official Journal and made available through EUR-Lex and the Publications Office of the European Union. Case law comes from the Court of Justice of the European Union — the Court of Justice and the General Court — on curia.europa.eu. Regulatory guidance sits with EU agencies and bodies such as the European Data Protection Board, the EBA, ESMA, EIOPA, and the ECB. Materials are published across the EU's 24 official languages.
EU law moves quickly: regulations and directives are amended continuously, agencies publish a steady stream of guidelines and enforcement decisions, and much national law across the Member States is EU-derived — from the GDPR to financial-services and product rules. Because directives are transposed into national law while regulations apply directly, point-in-time data straight from the source is what keeps an EU legal research answer correct today.
