Can I challenge an arbitration award in Norway if I never got to see key evidence?

Norway allows a court to set aside an arbitration award, but it does not provide a right to appeal the merits. The remedy is annulment if the process was fundamentally flawed.

Grounds under Section 43 include: Due Process Violation (not given proper notice or unable to present your case); Invalid Agreement (arbitration agreement invalid); Excess of Mandate (award concerns a dispute outside the submission); Composition Error (tribunal not formed according to agreement or law); Public Policy (award or process violates Norwegian legal principles); Non-Arbitrability (subject matter cannot be arbitrated in Norway).

Your specific case: late evidence. If the arbitrator allowed the other side to submit surprise documents and you lacked a meaningful opportunity to respond, this may be a due process violation. Norwegian courts take the right to be heard seriously; if the error likely influenced the outcome, Oslo District Court can declare the award null and void.

Deadline: The strict three-month deadline is set in Section 44. It runs from the date you received the award. If you requested a correction or an additional award, the deadline runs from when you received the tribunal's decision on that request. This is a preclusive deadline: missing it usually forecloses your challenge.

Next steps: In Oslo, file with the Oslo District Court. Even if you win, the court will not replace the award with its own decision; it will scrap the old one, meaning you might have to start the arbitration over unless the arbitration agreement itself is found invalid.
