Article Summaries:
- CERN’s revised Operational Circular No. 11 (OC 11), “The processing of personal data at CERN,” entered force on 1 February 2026 after Director‑General approval on 17 December 2025. The new circular replaces the 2019 version and its 2021 annexes, modernising the organisation’s data‑privacy framework while retaining core principles. It aligns CERN’s rules with EU GDPR, enhances legal certainty, and simplifies implementation for services. Key updates clarify scope, remove the “regular processing” concept, adopt a risk‑based DPIA approach, streamline breach notifications, and reduce approval requirements for internal and external data transfers, supporting technological neutrality and long‑term viability.
