CJEU ruling on Dun & Bradstreet clarifies GDPR's ‘right to an explanation,' balancing understandability with trade secrets. The court restricts detailed disclosures, potentially limiting individuals' ability to contest AI decisions, resulting in a ‘pyrrhic victory.' While explanations must be clear, they may not substantively empower individuals against problematic AI, and data controllers could misuse disclosure processes to evade accountability. Thus, the practice of contestation faces challenges despite the ruling's intent.
