Marius Borg Høiby, the eldest son of Norway’s Crown Princess Mette-Marit, was sentenced to four years in prison on Monday, June 15, 2026, after being convicted of rape by Oslo District Court. The verdict marks the dramatic conclusion of one of the most high-profile criminal trials in Norwegian royal history — a case that has sent shockwaves through the Scandinavian monarchy and gripped international audiences for over a year.
Who Is Marius Borg Høiby?
Marius Borg Høiby, 29, is the son of Crown Princess Mette-Marit from a relationship before her 2001 marriage to Crown Prince Haakon, the heir to Norway’s throne. Although he grew up within the royal household, Høiby is not formally a member of the Royal House of Norway and holds no official royal title or duties. He has no steady job and had, until recent years, largely stayed out of the spotlight.
His mother, Crown Princess Mette-Marit, is currently gravely ill with a form of pulmonary fibrosis and has recently been placed on a lung transplant list, adding a deeply personal dimension to an already agonising public scandal.
The Charges: 40 Offences Over Six Years
The case against Marius Borg Høiby was extraordinarily wide-ranging. He faced a total of 40 charges, spanning crimes committed between 2018 and 2024. The most serious allegations involved four counts of rape against women who prosecutors said were either asleep or otherwise incapacitated and unable to give consent.
Beyond the rape charges, prosecutors alleged:
- Repeated domestic violence against a then-girlfriend between mid-2022 and autumn 2023 — including punching her in the face, choking her, slamming a door into her, and throwing objects at her
- Secretly filming the genitals of several women without their consent
- Delivering nearly eight pounds (approximately 3.5 kilograms) of marijuana
- Making death threats
- Violating restraining orders on multiple occasions
- Various traffic offences, including reckless motorcycle driving
- Harassing police officers and causing property damage
The case involved six women in total, though the charges that went to verdict focused on four of them.
The Trial: Six Weeks That Shook Norway
The trial ran from February 3 to March 19, 2026, at Oslo District Court — a gruelling six-week proceeding that laid bare details of Høiby’s private life, his struggles with mental health, and his alleged pattern of abuse. The hearings attracted massive media attention both in Norway and internationally.
During the proceedings, Høiby pleaded not guilty to all rape charges but admitted to a number of lesser offences, including transporting the marijuana consignment and violating restraining orders. He also partially admitted to aggravated assault connected to an incident in Oslo in August 2024.
On the stand, Høiby offered a revealing look at the psychological toll of his public upbringing. He stated that growing up in the public eye had caused him to crave drink and sex, and described the scrutiny he faced as having effectively erased his identity. “My whole life is common property,” he said during the trial. “I am no longer Marius, I’m a monster.”
His defence lawyer, Petar Sekulic, argued that the media coverage of the case had been excessive to the point of unfairness, describing it as borderline unprecedented in its intensity.
What the Court Decided
The three judges presiding over courtroom 250 at Oslo District Court found Høiby guilty of two of the four rape charges. One of the rapes for which he was convicted took place in 2018 at the crown prince couple’s official residence. He was acquitted on the remaining two rape counts.
In addition to the rape convictions, the court found him guilty of repeated domestic violence, drug-related offences, making threats, restraining order violations, and traffic offences.
Høiby was not physically present in court for the sentencing, reportedly due to unspecified medical reasons, but he followed the proceedings via video link from his location under custody. Only one of the rape victims was present in the courtroom; she shed tears as the judge read out the guilty verdict in her case.
The Sentence: Four Years, Far Below What Prosecutors Sought
Oslo District Court sentenced Marius Borg Høiby to four years in prison — a sentence that fell significantly short of the seven years and seven months requested by prosecutors, but far exceeded the 18 months his defence team had argued for.
Prosecutors had pushed for the heavier sentence based on the seriousness of the rape convictions and the cumulative nature of the offending across multiple victims over multiple years. Defence lawyers, for their part, had called for a complete acquittal on all rape charges, arguing that the admitted lesser offences warranted only a limited custodial term.
The sentence is not yet final. Høiby retains the right to appeal, and his legal team is expected to consider that option in the coming days.
A Timeline of the Case
The road to Monday’s verdict began in 2024, when Høiby was repeatedly arrested amid escalating allegations of wrongdoing:
- August 2024: Høiby was first arrested following an alleged attack on a 20-year-old woman in Oslo.
- November 2024: A second arrest followed on suspicion of rape — specifically, sexual intercourse with someone unconscious or otherwise unable to resist.
- August 2025: Prosecutors formally charged Høiby with 32 counts including rape, domestic violence, and assault. Oslo state attorney Sturla Henriksbo confirmed the indictment.
- January 2026: Six additional charges were added, including serious drug violations and further restraining order breaches.
- February 1, 2026: On the eve of trial, Høiby was arrested again on allegations of assault, restraining order violations, and threatening someone with a knife. He remained in custody throughout the trial.
- February 3 – March 19, 2026: The six-week trial took place at Oslo District Court.
- June 15, 2026: Verdict and sentencing delivered — four years in prison.
Impact on the Norwegian Royal Family
The case has been an acute source of embarrassment and anguish for the Norwegian monarchy. Crown Prince Haakon issued a carefully worded statement before the trial began, acknowledging the family’s care for Høiby while firmly distancing the institution from any special treatment. “Marius Borg Høiby is not a member of the Royal House of Norway and is therefore autonomous,” he said. “He is a citizen of Norway and, as such, has the same responsibilities as everyone else — as well as the same rights.”
Despite the official distance, the personal pain has been very much on display. Crown Prince Haakon, Crown Princess Mette-Marit, and Prince Sverre Magnus were reported to have visited Høiby in Oslo Prison in the weeks before the verdict. The family’s situation has been compounded by the Crown Princess’s deteriorating health, with observers noting that the twin crises — her son’s criminal trial and her own placement on a lung transplant waiting list — have pushed the monarchy into a period of profound difficulty.
Mette-Marit’s earlier revelation that she had shown what she herself described as poor judgment in having contact with convicted sex offender Jeffrey Epstein added yet another layer of turbulence to an already difficult period for the royal household.
Reactions and What Comes Next
The sentencing has drawn widespread reaction across Norway and beyond. Many observers had expected a harsher sentence given the nature of the convictions, while others noted that the four-year term was still significant for a case where acquittals on two of the four rape counts reduced the scope of criminal liability.
Advocates for survivors of sexual violence pointed to the emotional moment in the courtroom when a victim’s tears greeted the guilty verdict as a reminder of the human cost at the heart of the case.
With the possibility of an appeal looming, the legal story of Marius Borg Høiby may not yet be over. His defence team’s next steps will be closely watched by a Norwegian public that has followed every development in this extraordinary saga.
