Greece publishes AI Act implementation law with public-sector AI registry
Law 5321 assigns national oversight roles and requires Greek public bodies to register AI projects before they begin operating.
Greece published Law 5321 on July 22, establishing its national framework for applying the European Union's AI Act. The measure names the country's governance structure for AI oversight and creates a unified registry for AI systems used by public-sector bodies.
What the law does
The government's AI and Data Governance Secretariat says Law 5321 defines the competent national authorities responsible for applying and supervising the AI Act. It also replaces the AI-related provisions of Greece's earlier Law 4961/2022, bringing the national framework into line with the European regulation.
Article 21 creates a Unified Register of Artificial Intelligence Systems within the secretariat. A Greek public-sector body that plans to use an AI system must submit a registration declaration for the project before the system starts operating. The official announcement presents that inventory as a tool for transparency, accountability and more effective oversight of government AI use.
The law also provides mechanisms for supervision and cooperation with European Union bodies. Transition provisions are intended to give public agencies and other affected organisations a path into the new obligations.
Why it matters
The registry requirement moves public-sector AI governance from a general policy goal toward an operational record of which systems government bodies plan to use. Requiring registration before operation gives supervisors an earlier view of deployments, while named authorities clarify who is responsible for national implementation.
For public administrators, the immediate task is preparing projects for registration and the wider compliance structure. The ministry says its secretariat will support public bodies with guidance and tools for applying the framework.
The announcement does not provide a detailed technical design for the registry or a full implementation timetable for each obligation. Those operating details are the next point to watch as agencies translate Law 5321 into procedures.
Status
Confirmed. Greece's official AI and Data Governance Secretariat announced the publication of Law 5321. Internal confidence is medium because the article relies on two pages from the same government authority rather than independent reporting.
