Digital welfare fraud detection and the Dutch SyRI judgment (2509.23843v1)

Abstract: In 2020, a Dutch court passed judgment in a case about a digital welfare fraud detection system called Systeem Risico Indicatie (SyRI). The court ruled that the SyRI legislation is unlawful because it does not comply with the right to privacy under the European Convention of Human Rights. In this article we analyse the judgment and its implications. This ruling is one of first in which a court has invalidated a welfare fraud detection system for breaching the right to privacy. We show that the immediate effects of the judgment are limited. The judgment does not say much about automated fraud detection systems in general, because it is limited to the circumstances of the case. Still, the judgment is important. The judgment reminds policymakers that fraud detection must happen in a way that respects data protection principles and the right to privacy. The judgment also confirms the importance of transparency if personal data are used.
