Criminal Defense

Our White Collar Criminal Defense group is frequently retained by corporate and individual clients who have been identified as witnesses in, or subjects or targets of, ongoing investigations. We have had great success in minimizing our clients’ exposure, frequently helping them avoid regulatory sanctions and criminal prosecution. We are also experienced trial lawyers and have an excellent track record in criminal trials and appeals.

Our Paris team has extensive trial experience before a wide variety of French courts, and notably the French financial prosecutor (PNF – Parquet national financier) regarding white collar criminal cases.

In this Law360 profile, John W Gibson discusses his five-year stint as a senior prosecutor and investigations manager in the UK Serious Fraud Office’s bribery and corruption unit, how he uses that experience to understand what matters when engaging with regulators and prosecutors, and how to deploy effective litigation strategy in criminal or compliance matters.

Tim Harris joins host Nicolas Corry on the Skadi Podcast to discuss internal investigations, looking at why an external party might be brought in to conduct an investigation and the role of individuals in these investigations. In addition, the podcast looks at the implications of the Senior Managers Regime and discusses the recent high-profile criminal cases of Serco and NatWest.

John Gibson spoke with Financial News to discuss the Financial Conduct Authority’s recent warning that the agency is keeping a close eye on the use of unauthorised messaging apps in finance.

“The really critical thing for firms to do is to not ignore warning signs… [or] turn a blind eye to situations in which they [firms] know that private devices are being used for business purposes,” said John, adding that doing so represented “unquestionably [a] failing in your regulatory obligations.”

“The way in which people are working remotely and using chat applications, is storing up risk for both institutions, and for their potential supervision and enforcement of the rules,” added John. (Subscription required.)

Tim Harris spoke with Law360 to discuss the Financial Conduct Authority’s first prosecution of a UK bank for failing to comply with anti-money laundering rules. Tim observed that the prosecution "crystallizes the criminal risk for firms.” He added that "Up until now the criminal aspects of the money laundering regime, at least for firms, have been somewhat theoretical. For a U.K. retail bank to be prosecuted is a watershed moment and shows the FCA coming good on its goal to give teeth to the regime." He also provided his thoughts on the court’s approach to sentencing in the event the bank pleads or is found guilty and also the potential application of the Senior Managers Regime.

Richard added that he “wouldn't rush to judgment on Osfosky's interaction with the go-between until everything is clear." (Subscription Required)
