Oslo District Court has sentenced Marius Borg Høiby to four years in prison on 40 criminal charges, including sexual assault and assault. One of those convictions concerns an assault against his former girlfriend, Nora Haukland. Høiby has filed an appeal, which means the verdict is not yet legally final.

The sheer number of charges is striking. Rather than focusing on one incident, prosecutors built their case on a pattern of behavior — 40 separate criminal acts spanning multiple categories of violence. VG reported in May 2026 that a verdict was expected on June 15, the date it was handed down.

Høiby, 29, is the son of Crown Princess Mette-Marit, who married Crown Prince Haakon in 2001. That family tie has kept this case in the public eye far more than a typical criminal case would be. The Norwegian Royal House has worked hard to manage how the case is discussed. In a statement on January 28, 2026, Crown Prince Haakon said that Marius "is not part of the Royal Household, but stands freely," while also saying the family cares for him and considers him important to them. The wording is careful — it acknowledges a personal connection without suggesting that the royal institution bears any responsibility for him or that he holds any official royal status.

Now comes the legal reality. Under Norwegian procedure, when someone appeals a district court conviction, the case doesn't just get reviewed for errors — it goes back for a full retrial in a higher court, called the Court of Appeal (lagmannsretten). A four-year sentence automatically qualifies for appellate review without any additional procedural steps needed. Until that appellate process finishes, or until the deadline to appeal passes unused, the sentence has no legal force. NRK confirmed the appeal has been filed.

Here is what matters beyond the courtroom. Høiby holds no constitutional role and receives no public money because of royal status — the Crown Prince's statement made that entirely clear. But there is a reputational angle. The Norwegian Royal House has enjoyed unusually high public approval by Nordic standards, and cases like this keep the institution under scrutiny. The appellate proceedings will extend that attention well into the coming year, simply because the judicial process is not quick.

Norwegian courts do not create special procedures for high-profile defendants. The appeal will follow the normal schedule. Given the volume of evidence behind 40 charges, the Court of Appeal hearing could be lengthy. A final resolution to this case remains a considerable distance away.
