As data protection professionals, understanding key legal decisions and their ramifications is critical to our role. A recent ruling by the Marktenhof (Court of Appeal) in Belgium regarding IAB Europe highlights important developments in data privacy law, specifically concerning the Transparency and Consent Framework (TCF).
Background and Context
In early 2022, the Belgian Data Protection Authority (Gegevensbeschermingsautoriteit or GBA) imposed a fine of €250,000 on IAB Europe for violations related to their TCF, which facilitates the administration of user preferences for personalized online advertising through Real Time Bidding (RTB). The GBA’s decision, endorsed by EU data protection authorities, emphasized that the TC String—a structured data string reflecting user preferences within the TCF—constitutes personal data under GDPR. Consequently, IAB Europe was considered a joint data controller.
Ruling Analysis
Fast forward to 2025, the Marktenhof supported the GBA’s initial position that the TC String is personal data, affirming that IAB Europe acts as a joint data controller. This alignment with earlier decisions underscores the stringent interpretation of data handling and the responsibilities tied to data processing frameworks like the TCF. However, the court annulled the GBA’s decision 21/2022 solely on procedural grounds, not affecting the substantive legal standing of the TC String as personal data.
Repercussions for Data Protection Practice
This ruling carries significant weight for data protection strategies across Europe. Organizations utilizing similar frameworks must reassess their data handling practices under GDPR to ensure compliance, especially around consent and data controller responsibilities.
Understanding these legal nuances is crucial. Data protection experts must now guide organizations to align consent frameworks with GDPR stipulations, focusing on clear accountability mechanisms. This decision marks a firm reminder of the legal landscape’s evolving nature and the importance of continuous adaptation to regulatory expectations.
Such judicial outcomes necessitate a proactive approach from data protection professionals, emphasizing the importance of reviewing and updating compliance measures in collaboration with legal teams.
