A&O Shearman is recognised for its pragmatism in directing internal investigations into claims of corruption, bullying, discrimination, trade secret misappropriation, conflicts of interest, and sanctions breaches. Many mandates stem from whistleblower reports and require thorough fact-finding processes. The practice is helmed by Wolf Bussian, who conducts finance-sector investigations concerning allegations of market manipulation, fraud, and insider trading, and Jan Erik Windthorst, who advises on compliance investigations and represents clients before courts, arbitral tribunals, and regulatory bodies. Tim Nikolas Müller handles domestic and cross-border misconduct cases, often involving bribery, embezzlement, money laundering, and tax offences.
