Over the last decade, Paul has focused on corporate crime, cartel offences, corruption, regulation and compliance and on related civil matters. Paul has acted for individuals, public figures, companies and other organisations. He is increasingly being sought out to assist in either conducting internal inquiries or to protect the interests of corporate clients who are subject to such inquiries from regulatory or prosecuting authorities.
