Internal investigations

Within: Internal investigations

Hengeler Mueller’s practice combines expertise in the areas of compliance, internal investigations and white-collar crime; it also works closely with other areas, such as criminal procedural law, corporate, antitrust, data protection and insolvency law. It is conducting internal and external investigations for the Robert Bosch group globally in connection with the alleged manipulation of nitrogen oxide emissions from diesel vehicles. In addition, Hans-Jörg Niemeyer’s team recently successfully completed the representation of Calsonic Kansei; following the EU Commission’s antitrust investigation, the firm defended claims for damages. Daniel Weiß assisted an international retail group with investigating suspected fraud. The group was strengthened at the senior associate level: Ralf Christian van Ermingen-Marbach, who has expertise in white-collar crime and internal investigations, joined from the Düsseldorf public prosecutor’s office. Dirk Uwer and Wolfgang Spoerr also deserve special mention.
