Administrative Sanctions and Criminal Liability

The risk landscape for businesses is becoming increasingly complex. One of the characteristics of this complexity is a rapidly changing regulatory environment. In addition, public authorities are more active than ever in sanctioning violations.

The inability to recognize risks associated with possible criminal actions can have serious consequences for businesses, both in terms of criminal liability, administrative sanctions and additional taxes, as well as in relation to the company's reputation. Board members may also be subjected to responsibility for wrongdoings on an individual basis.

We provide comprehensive assistance related to administrative sanctions and criminal liability. Our lawyers have experience from key government agencies such as the Financial Supervisory Authority, the Norwegian Police Security Service (PST), the Consumer Authority, the Competition Authority, the National Authority for Investigation and Prosecution of Economic and Environmental Crime (Økokrim), and the general prosecution authority.
