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 large-scale and complex criminal investigations at the Office of the Attorney General of Switzerland. Today, I use this experience to assist individuals and institutions who are facing charges in white-collar crime cases or who have been harmed by economic crimes.
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.
Together with other federal prosecutors and the Swiss Federal Criminal Police, I led extensive cross-border investigations into corruption and money laundering. These included, among other things, successfully concluded cases against Alstom and a member of the Gaddafi family, as well as numerous investigations related to the Petrobras/Odebrecht scandal in Brazil.
This experience has had a lasting impact on my perspective on complex white-collar crime cases: on the progression of an investigation as well as on the presentation of evidence, international cooperation, and the strategic decisions that shape the course of a case.
Defense and Representation of Injured Parties
Today, I apply my experience in the legal field.
I represent individuals and institutions who are defendants in white-collar crime cases, as well as victims of white-collar crimes.
International Corruption and Money Laundering Cases
International corruption and money laundering cases are often characterized by multiple jurisdictions, cross-border financial flows, and cooperation among various law enforcement agencies.
My work at the Office of the Federal Prosecutor involved such cases for many years. In the course of this work, I developed close ties with leading law enforcement officials worldwide, as well as with the investigative authorities of the World Bank and the European Development Bank.
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.
As a result, my practical experience encompasses not only traditional white-collar crime law but also federal administrative criminal law.
