Administrative sanction of 2 December 2025
Executive Summary
The CSSF imposed an administrative sanction on 2 December 2025 against an approved statutory auditor (*réviseur d’entreprises agréé*) for breaches of professional obligations, likely related to continuing education requirements under Luxembourg's Audit Law, mirroring patterns in recent similar cases. This enforcement action underscores the CSSF's rigorous oversight of audit professionals, emphasizing compliance with ongoing training mandates to maintain audit quality and market integrity. Compliance professionals should note it as evidence of heightened scrutiny on non-delegable professional duties. #

This is not a regulatory change or new requirement but an enforcement action applying existing rules under point f) of Article 43(1) read with point a) of Article 43(2) and Article 44 of the Law of 23 July 2016 on the audit profession (Audit Law), alongside CSSF Regulation N°16-10 on continuing education.
