Marius Borg Høiby, the son of Norway’s Crown Princess Mette-Marit, was sentenced to serve four years in prison after he was found guilty of several charges, including two counts of rape.
In addition to his prison sentence, Høiby, 29, was also sentenced to a two-year restraining order against one of his victims, according to The Guardian.
Oslo District Court announced Høiby’s conviction and sentence on Monday, June 15, nearly three months after his six-week trial concluded. Høiby was not physically in court for the verdict and instead attended via video link, according to BBC.
Judge Jon Sverdrup Efjestad convicted Høiby of assaulting his former girlfriend Nora Haukland, who is the only victim that was publicly named in the case. Efjestad was ordered to pay Haukland and three other women compensation and he was also acquitted of two other charges of rape, per The Guardian.
During the trial, prosecutors argued that Høiby should be given seven years and seven months in prison. Meanwhile, his defense lawyers said he should only serve 18 months.
Høiby was arrested for allegedly attacking a 20-year-old woman in 2024, and he was initially charged with 32 counts, which included rape and sexual abuse, on August 18, 2025.
He was facing a total of 38 charges, which included six counts of filming people without their consent, six counts of sexually offensive conduct without consent, attacking a former partner and violating a restraining order, as well as drug and driving offenses.
Mette-Marit, 52, welcomed Høiby during a previous relationship before she married Crown Prince Haakon, the future king of Norway, in 2001. Høiby is not in the line of succession to the throne, though his half-siblings Princess Ingrid Alexandra and Prince Sverre Magnus are.
Haakon, 52, issued a statement about the charges pressed against Høiby on January 28. “Our thoughts are with everyone who is affected by this case. It has an impact on the individuals, their families and all those who care about them. We understand that this is a difficult time for many of you, and we sympathise,” Haakon said, according to People.
“At the same time, it is reassuring to know that we live in a state governed by the rule of law,” Haakon added. “I am confident that those responsible for overseeing the proceedings will ensure that the trial is conducted in as orderly, proper, and just a manner as possible.”
