What does CSSF's "Administrative sanction of 11 September 2025" change?

Administrative sanction of 11 September 2025

Published 9 January 2026 | Luxembourg

AI Analysis

The CSSF imposed a **€10,000 administrative fine on Sunbricks GP S.à r.l.**, an alternative investment fund manager, for failing to submit a mandatory annual financial crime questionnaire by the April 4, 2025 deadline, despite two formal reminders. This enforcement action demonstrates the CSSF's strict approach to cooperation obligations under Luxembourg's anti-money laundering and counter-terrorist financing (AML/CFT) framework and signals that non-submission of required compliance documentation—even without evidence of underlying financial crime—triggers regulatory penalties.

Key dates

April 4, 2025 Deadline: – Annual financial crime questionnaire submission deadline (for year ending December 31, 2024)
Before September 11, 2025: – Two reminder notices issued by CSSF to Sunbricks GP
September 11, 2025: – Administrative fine decision date; questionnaire still not submitted
January 9, 2026: – Publication date of enforcement decision
