Marius Borg Høiby, the 29-year-old son of Norway’s Crown Princess Mette-Marit, remains in custody after the Oslo Court of Appeal rejected his request for release on June 10, 2026. The court determined that the risk of the defendant reoffending outweighed his desire to be with his mother, who is currently undergoing treatment for pulmonary fibrosis. Høiby faces 40 charges, including allegations of violence and drug offenses, with prosecutors seeking a prison sentence of seven years and seven months.
Why was the request for release denied?
The Oslo Court of Appeal overturned a lower court’s decision, concluding that the risk of Marius Borg Høiby committing further offenses remains a significant concern. While the Oslo District Court had previously ruled that his abstinence from illicit substances while incarcerated made continued detention “disproportionately intrusive,” the appellate court disagreed. According to court filings, the severity of the 40 charges—which include claims of aggression toward former partners—necessitates his continued confinement ahead of the verdict scheduled for June 15.
Marius Borg Høiby is not a working member of the Norwegian royal family. He is the son of Crown Princess Mette-Marit and Norwegian businessman Morten Borg, and he holds no official royal title or representative duties.
What are the primary allegations against Høiby?
Prosecutors have leveled 40 distinct charges against Høiby, spanning from drug possession to violent conduct. During his trial, which ran from February 3 to March 19, Høiby pleaded guilty to several counts, including possessing marijuana, driving without a valid license, and violating a restraining order. However, he has consistently denied the most serious accusations, which involve the alleged abuse of four women. One piece of evidence, a video reportedly retrieved from his phone and presented by prosecutors, led to a emotional breakdown from the defendant on the first day of his trial.
How does the case impact the Norwegian Royal Family?
The legal proceedings have intensified public scrutiny regarding the private lives of the royals. Nora Haukland, a former girlfriend of Høiby, testified that she previously sought help from Crown Prince Haakon and Crown Princess Mette-Marit regarding Høiby’s behavior, alleging they dismissed the matter as not their responsibility. Høiby disputed this account in court, describing his mother and stepfather as “the kindest people in the world.” Beyond this case, the family has faced recent pressure following revelations in January 2026 that Crown Princess Mette-Marit had past contact with the late financier Jeffrey Epstein, an association she has since publicly apologized for and characterized as “poor judgment.”
Comparison: District Court vs. Court of Appeal
| Authority | Ruling | Primary Justification |
|---|---|---|
| Oslo District Court | Release Granted | Substance-free status in prison; detention deemed “disproportionately intrusive.” |
| Court of Appeal | Release Denied | Risk of reoffending remains; severity of charges outweighs personal circumstances. |
What happens next for the defendant?
Høiby is slated to be transferred from Oslo Prison to Ila, a high-security correctional facility, due to the upcoming closure of his current detention center. His legal team, led by Petar Sekulic and Ellen Holager Andenæs, expressed significant disappointment regarding the appellate court’s ruling. The final verdict is expected on June 15. If convicted on the primary charges, he faces a potential sentence of nearly eight years.
