Stefan Lenz, Attorney at Law, LL.M.
I am an attorney and a former federal prosecutor. My practice focuses on white-collar crime, particularly complex cases involving international corruption and money laundering.
From 2002 to 2016, I conducted complex criminal investigations with national and international implications at the Office of the Attorney General of Switzerland. This experience now forms an essential foundation for my work as an attorney.
White-Collar Crime Law from the Perspectives of Law Enforcement and the Defense Attorney
During my fourteen years with the Office of the Attorney General, I focused primarily on international corruption and money laundering.
Gemeinsam mit weiteren Staatsanwälten des Bundes und der Schweizerischen Bundeskriminalpolizei führte ich umfangreiche grenzüberschreitende Verfahren. Dazu gehörten unter anderem Verfahren gegen Alstom und ein Mitglied der Gaddafi-Familie sowie zahlreiche Untersuchungen im internationalen Petrobras-/Odebrecht-Komplex.
This work has had a lasting impact on my perspective on white-collar crime proceedings: on the progression of an investigation as well as on the presentation of evidence, international cooperation, and the strategic decisions that determine the course of a proceeding. In the course of this work, I also established close ties with law enforcement agencies in various countries, as well as with investigative units at the World Bank and the European Bank for Reconstruction and Development.
Operation Lava Jato / Odebrecht
I have been involved in the Petrobras/Odebrecht case (Operation Lava Jato) in various roles since the Swiss investigations began. After leaving the Office of the Attorney General of Switzerland, I advised the Peruvian Public Prosecutor’s Office on evidence seized in Switzerland, analyzed more than 155,000 files from the Odebrecht systems MyWebDay and Drousys, and testified as an expert witness before a court in Lima in 2024.

Defense and Representation of Injured Parties
Today, I represent individuals and institutions that are defendants in white-collar crime cases, as well as victims of fraud, corruption, money laundering, and other economic crimes—including in cross-border proceedings.
Experience in Administrative Criminal Law
After starting my private law practice, I worked part-time as an investigating officer for the Federal Office of Transportation from 2023 to 2024. There, I conducted criminal proceedings related to complex cases of subsidy fraud.
