Belgian Market Court Ruling on IAB Europe and the TCF: Where to Find the Latest Guidance

Rather than restating or interpreting the judgment in detail, we want to ensure members have access to the most accurate, up-to-date, and comprehensive information directly from IAB Europe and trusted legal analysis. 

What’s changed? 

The ruling relates to the Belgian Market Court’s assessment of earlier decisions made by the Belgian Data Protection Authority concerning the TCF. While the judgment is an important development, its practical implications are nuanced and best understood through the official explanations already published. 

To avoid confusion and ensure clarity, IAB Europe has consolidated its position and guidance in a set of authoritative materials. 

Recommended reading 

We strongly encourage members to review the following resources, which together provide the clearest picture of what the ruling does, and does not, change: 

• IAB Europe’s latest official announcement, outlining the outcome of the case and its significance for the TCF 

• The updated FAQ document, which addresses key questions from publishers, advertisers, and technology providers 

• Peter Craddock’s LinkedIn post, offering a clear and accessible legal summary of the ruling and its implications in practice 

These materials reflect the most current understanding and should be treated as the primary reference point. 

Why this approach matters 

Data protection law and regulatory enforcement in the advertising sector remain complex and fast-moving. By relying on official statements and expert legal commentary, organisations can better assess any operational or compliance considerations without the risk of outdated or incomplete interpretations. 

We will continue to monitor developments closely and share further updates where relevant. In the meantime, the resources above are the best place to start for anyone seeking clarity on the Belgian Market Court ruling and the future of the TCF.
