Enforcement authorities increasingly have acknowledged the valuable input derived from cooperation in cases that resulted in record fines. By way of example, the French National Financial Prosecutor’s Office specifically detailed the role of the Joint Investigation Team set up with the Serious Fraud Office in its settlement with Airbus. Similarly, in the Petrobras case, the Department of Justice publicly praised the assistance of its Brazilian law enforcement counterparts. It is thus predictable that many future international corruption cases likewise will be resolved using cross-border cooperation. During this panel, representatives of prosecution authorities will explain how they cooperate with each other in practice. Our panellists will focus on how information and potential evidence are exchanged at the investigation stage. The panellists will also share their experience in dealing with local legal constraints, including so-called blocking statutes, that may obstruct cooperation. Speakers will also share their experience in reaching coordinated cross-border settlements and in calculating fines that will ultimately be divided among the authorities.
