Walder Wyss defended a former top manager of a global investment bank in a cross-border money laundering investigation that spanned more than a decade. The focus was on alleged bribery payments amounting to millions to a former Greek defence minister.

Our team, led by Oliver Kunz, took charge of the defence strategy throughout the proceedings. This led to a successful appeal before the Appeals Chamber of the Federal Criminal Court in 2023. In its ruling of 24 September 2025, the Swiss Federal Supreme Court dismissed the appeal lodged by the Office of the Attorney General in its entirety (6B_1180/2023). As 92 of the 96 charges were ultimately dismissed, only a minimal suspended sentence remained, representing a complete reversal of the original verdict.
