European Parliament and Council adopt the AI Act

Background

The AI Act began as a Commission proposal submitted in April 2021 ^[2]. For the Commission, the proposal was the starting point of a legislative process that would need agreement between the European Parliament and the Council of the EU. The fact that the proposal was submitted in 2021 and that the two institutions reached a provisional agreement on 8 December 2023 shows that the text went through a negotiation period before the formal votes ^[2]. In the EU system, a provisional agreement is a sign that the institutions have converged on a text, but it is not the final legal step; formal adoption by the legislative bodies follows. The Council later presented the act as the first worldwide rules on AI ^[2]. That description is the central claim attached to the adoption: the EU institutions were not only approving a regional law but presenting it as a global first.

What happened

The decisive parliamentary step came on 13 March 2024, when the European Parliament approved the AI Act by 523 votes in favour, 46 against and 49 abstentions ^[1]. The size of the majority and the presence of both opposition and abstention give the vote a concrete political shape: support was broad, but not unanimous. The Parliament's approval was followed by the Council of the EU's formal adoption of the act on 21 May 2024 ^[2]. With that second adoption, both institutions had taken their formal decisions on the text. The Council's own announcement described the act as the first worldwide rules on AI ^[2], a framing that became part of how the adoption was presented publicly.

Key details

The sequence matters. The Commission submitted the proposal in April 2021 ^[2]. The Parliament and Council reached a provisional agreement on the text on 8 December 2023 ^[2]. The Parliament then voted on 13 March 2024 ^[1], and the Council formally adopted the act on 21 May 2024 ^[2]. After signature by the presidents of the European Parliament and of the Council, the act was to be published in the Official Journal and take effect 20 days after publication ^[1]. These steps separate political agreement, parliamentary approval, formal adoption by the Council, signature, publication and entry into effect. The vote count belongs to the parliamentary stage; the Council's formal adoption belongs to the later stage; publication and the 20-day period belong to the final stage. Laid out in order, the adoption appears not as a single event but as a series of decisions by different institutions and a series of procedural points.

Significance

The act's significance, as presented by the Council, lies in its description as the first worldwide rules on AI ^[2]. That claim is about timing and scope at the global level: the Council did not describe the act merely as an EU measure, but as the first set of rules of its kind anywhere. The adoption also shows how the EU's institutions moved from a Commission proposal in April 2021 to a provisional agreement in December 2023, then to parliamentary approval in March 2024 and Council adoption in May 2024 ^[2][1]. For readers following AI governance, the event is a case study in a long legislative path: proposal, negotiation, provisional agreement, formal votes, signature and publication. The final stage was publication in the Official Journal and effect 20 days after publication ^[1]. The Council's description of the act as the first worldwide rules on AI is the clearest statement of why the adoption was presented as a global first ^[2].
