Disputes challenge both the people and the businesses involved. It is essential to limit the disputes’ impact on the daily operations of a business.
We have extensive experience in resolving disputes both in and outside the courts. Many disputes are a fight for facts. Our lawyers find what is necessary. Project management is critical, team selection is essential. Thommessen has cutting edge expertise and versatility. Our litigation specialists work closely with our technical professionals and market experts. The right people get involved at the right time in the process. The use of resources should always correspond to the importance of the case. We take neither shortcuts nor any detours.
Dispute resolutions are to be a professional exercise. We place emphasis on the fact that disputes should be resolved without straining the relation between the parties involved.
We have about twenty lawyers admitted to litigate before the Supreme Court and we regularly litigate before our nation's highest court. Several of our attorneys have litigated cases before the EFTA Court and the European Court of Human Rights. Our lawyers are often used as arbitrators in commercial disputes.
