Belgium's privacy supervisor may take action against Facebook for what it considers "excessive" tracking of Belgian internet users.

Facebook tried to get out of enforcement by saying that only the Irish regulator can control the company.

But the Court of Justice of the European Union brushed that argument aside on Tuesday.

The Court's ruling is important for the enforcement of large tech companies under the GDPR, the European privacy rules that have been in force since 2018.

The Irish regulator is primarily designated to monitor Facebook in cross-border GDPR issues.

This is because the European headquarters of Facebook is located in Ireland.

But that does not mean that only the Irish supervisor can take on international affairs, the Court ruled on Tuesday.

According to Belgium, Facebook follows internet users excessively

The ruling is part of a case that the Belgian regulator brought against Facebook in 2015.

According to the Data Protection Authority (DPA), the company unlawfully and excessively monitors the surfing behavior of Belgian internet users, even if they do not have a Facebook account.

The regulator wants Facebook to stop doing so.

Dissatisfaction with enforcement by Irish regulator

Not only Facebook, but also many other tech giants have offices in Ireland.

The privacy investigations are piling up there, while decisions are not made.

There is dissatisfaction in the European Parliament about the lack of supervision by the Irish privacy authority.

MPs called on the European Commission in May to force Ireland to improve its enforcement.
