About

Provided by Advokatfirmaet Thommessen AS

Thommessen is a leading firm within the field of EU/EEA and competition law in Norway. We assist Norwegian and foreign companies with merger control processes, investigations, appeals and litigation proceedings and provide ongoing advice related to competition law, state aid law and other EEA law.

Since the EEA Agreement was signed in 1992, our lawyers have played an active role in the development of both EU/EEA law and Norwegian competition law. We were involved in drafting the legislation and have assisted Norwegian and foreign clients in an impressive of major and landmark cases – including as counsel before Norwegian courts, the Competition Appeals Board, the EFTA Court and the European Court of Justice.

We have been involved in most major cases within this area of law in Norway – from complex merger cases to possible violations of competition rules. Several of the cases have left significant footprints in judicial development and have been of great financial and commercial significance for our clients.

With this as a basis, we assist in transactions, contract negotiations and other commercial project work, in dispute resolution and in major investigations within a wide range of industries. We strive at being a constructive, solution-oriented and accessible partner.

Thommessen is generally recognised as having one of the country's top teams of specialists, and we have for many years been ranked in the top tier of independent surveys.
