2. The EDPB replaced the Article 29 Working Party
Before the GDPR, the principal European data protection coordination body was the Article 29 Working Party, commonly called WP29. It had been established under Directive 95/46.
WP29 issued influential opinions and guidance, but the GDPR created a more formal and powerful institutional system. Recital 139 expressly states that the EDPB should replace WP29 and should act as an independent Union body with legal personality.
The difference is important.
WP29 was predominantly advisory. The EDPB can still issue:
- guidelines;
- recommendations;
- best practices;
- advisory opinions.
However, the EDPB may also issue legally binding decisions under Article 65 when supervisory authorities cannot resolve specified disputes.
Illustration
Under the former system, if two national authorities disagreed over a cross-border case, the European coordinating body could express a view, but it did not possess the modern Article 65 power to bind those authorities through a formal dispute-resolution decision.
Under the GDPR, the EDPB can resolve:
- whether a relevant and reasoned objection should be followed;
- which authority is competent as lead authority;
- whether a mandatory Article 64 opinion has been wrongly ignored.
Article 68 therefore represents a move from relatively informal coordination to an institutionalised European enforcement structure.
It would nevertheless be an overstatement to blame the entire fragmented application of Directive 95/46 on WP29’s lack of legal personality. Fragmentation also arose because a directive required national implementation and left considerable room for national procedural and substantive variation. The EDPB’s stronger status forms only one part of the GDPR’s broader harmonisation framework.
