A court in Oslo is set to deliver its verdict on Monday in the case of Marius Borg Høiby, the 29-year-old son of Norwegian Crown Princess Mette-Marit, in a trial that has drawn sustained international attention and cast an uncomfortable spotlight on the Norwegian royal family. Prosecutors had called for a sentence of more than seven and a half years in prison.
Høiby faced more than 40 charges, tried over six weeks at Oslo's district court in February and March. The most serious allegations involve four counts of sexual acts against women who were incapacitated — asleep or intoxicated — a category classified under Norwegian law as sleep rape. He also faced charges of assault, threats, property damage, and drug offences. The prosecution argued that video recordings found on the defendant's own phone provided evidence for the rape charges; the defence countered that consent could not be ruled out and sought acquittal on those counts. Under Norwegian law, the potential sentencing range runs from a fine to a maximum of 16 years in custody.
Høiby grew up in an unusual position — informally known in the Norwegian press as the "bonus prince", a play on the Norwegian term for stepchild. He was four years old when his mother married Crown Prince Haakon in 2001, appearing on the palace balcony in a wedding photograph that became part of Norwegian public memory. Though raised within the royal family, he held no official royal status and had no defined role. In court, Høiby described feeling like "nothing" — known only as his mother's son — and said he had sought validation through alcohol and drug use, a spiral that began in his teenage years under constant tabloid scrutiny.
The case broke publicly in August 2024 when Høiby was arrested after reportedly causing a disturbance under the influence of drugs at a former girlfriend's apartment. What followed was a succession of revelations that proved difficult to ignore even for those with little interest in royal affairs. Witnesses and victims who testified during the trial offered accounts that prompted broader discussion in Norway about drug use and excess within the country's social elite — a world, commentators noted, that many Norwegians had preferred not to examine too closely.
The proceedings have placed the wider royal family in a painful position. Høiby's mother, Crown Princess Mette-Marit, is reported to be seriously ill with a lung condition. Høiby remained in pre-trial detention in the lead-up to the verdict, with the court declining to release him temporarily on the grounds that it could not trust him to observe a court-ordered no-contact restriction with a former girlfriend — something he described as deeply painful. The verdict will be closely watched both for its legal significance and for what it means for a royal institution that has staked part of its modern identity on openness and inclusivity.
