Corporate Crime

The Practice

Our Corporate Crime Group has extensive experience dealing with law enforcement agencies in Ireland and globally, as well as other investigative and prosecutorial bodies and regulators. Our experience extends to the defence and enforcement of regulatory and criminal breaches and our lawyers act for clients at all stages of regulatory and criminal enforcement processes from investigation to prosecution, including addressing the increasing commercial, regulatory and reputational risks which can arise in this area.

We are the only Irish member of FraudNet an international network of fraud litigation specialists founded by the International Chamber of Commerce. We are also the Partner Law Firm in Ireland for the global anti-bribery organisation, TRACE and provide expertise in anti-bribery laws and regulations for the benefit of TRACE’s multinational and intermediary members.

The Corporate Crime Group is listed as one of the top 100 firms for international investigations by Global Investigations Review 2018.
