Competition Law
Competition policy is about ensuring a fair and efficient marketplace. The purpose of competition law is to regulate the exercise of economic power — preventing monopolisation, cartels and other restrictions on free competition. The regulatory framework is extensive and complex, and the authorities’ toolbox — from merger control to the enforcement of prohibitions against cartels, anti-competitive cooperation and abuse of dominance — continues to expand. This requires a deep understanding of both business operations and the applicable regulatory environment, combined with strategic awareness and legal precision.
At Arntzen Grette, we have one of Norway’s most experienced and internationally oriented competition law teams. We assist clients at every stage, from commercial strategy and dialogue with authorities, to investigations, disputes and litigation. Our lawyers have extensive experience with merger control, compliance programmes and proceedings before the Norwegian Competition Authority, the European Commission, ESA, the EFTA Court and the Court of Justice of the European Union. We also represent clients in private enforcement cases and have argued matters before all levels of the Norwegian court system, including the Supreme Court.
Our team has been involved in numerous high-profile investigations and competition cases, both nationally and internationally. We have also been appointed trustee by the Norwegian Competition Authority in more cases than any other Norwegian law firm.
The advice from the team is always well considered, clear and responsible, but in addition to the law often also includes a strategic and commercial touch.
