Plesner provides advice on all aspects of corporate criminal law in connection with regulatory supervision, control and enforcement, including, if necessary, by representing the client in court.

Since the financial crisis, the Danish business sector has experienced increased and stricter regulation in areas such as capital market law (the Danish Securities Trading, etc Act, market abuse, insider trading, price manipulation etc) and in competition law (cartels, pricing agreements etc), tax, personal data and international trade.

The rules that the business sector must comply with make it possible to impose even harsher sanctions. Not only financial sanctions, but also criminal law sanctions. Recent developments in Denmark and internationally reflect an intensification of the authorities' focus, also on law enforcement, including fines and punishments to both companies and their managements.

In this connection it is quite simply becoming necessary to include special criminal law expertise and litigation expertise, not just in the application of the rules but especially also in the authorities' specific actions when conducting these criminal proceedings.

The competencies of Plesner's corporate criminal law team are based on a combination of experience from the Danish prosecution service, the Danish State Prosecutor for Serious Economic and International Crime, the Danish Security and Intelligence Service, the financial sector and a wide range of Danish and foreign specialist competencies. Jens Madsen is an important addition to Plesner's team. He is former head of the Danish State Prosecutor for Serious Economic and International Crime and the Danish Security and Intelligence Service and former Head of Investigation at Danske Bank and has extensive experience and in-depth knowledge of the authorities' working methods and how they act.

In addition to Jens Madsen, Plesner's team consist of highly qualified and experienced lawyers who are able to draw on the expertise of some of the leading experts in the various areas of the law.

Plesner also provides advice on anti-corruption and anti-money laundering. Our advisory services are based on in-depth knowledge of the increasingly complex and detailed legislation and the authorities' specific actions.

With our experience gained from many years of solving extensive, complex and delicate issues for companies of all sizes, including uncovering white-collar crime or any other irregularities, Plesner is also able to guarantee that a discreet, professional and efficient internal legal investigation can be carried out while the company is still running.
