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-compliance with minimum continuing education hours. #
What Changed
No new regulatory changes are introduced; this is 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 concerning the audit profession (Audit Law), alongside CSSF Regulation N°16-10 on continuing education for statutory auditors. Breaches typically involve failing to meet the minimum total hours of continuing education by the reference period end (e.g., December 31, 2024, as in a comparable August 2025 case). #
What You Need To Do
- Statutory auditors must immediately verify compliance with Article 3(1) of CSSF Regulation N°16-10, ensuring minimum continuing education hours are met for relevant periods
- Audit firms should conduct internal audits of training logs and implement remediation plans, including supplementary training if deficits exist
- All affected parties must report any identified breaches to CSSF proactively and retain evidence of corrective actions, as CSSF controls under Article 10 of the Audit Law can trigger fines
