Norwegian prosecutors have formally charged Marius Borg Høiby, the son of Crown Princess Mette-Marit, with 32 criminal counts including rape, violence, and illegal filming. The indictment marks a significant development in the year-long investigation into the royal stepson’s alleged crimes, with a potential 10-year prison sentence if convicted.
Marius Borg Høiby, 28, is the biological son of Norway’s Crown Princess Mette-Marit from a previous relationship and stepson to Crown Prince Haakon, the heir to the throne. Though connected to the royal family, Høiby holds no formal title or official duties. The charges stem from alleged incidents occurring primarily in Oslo between 2023-2024.
Oslo state prosecutor Sturla Henriksbø announced the indictment on August 18, 2025, following a comprehensive investigation that began after Høiby’s initial arrest in August 2024. The 32 charges include four counts of rape (one involving sexual intercourse, three without), domestic abuse against a former partner, physical violence against another woman, death threats, and illegally filming women’s genitals without consent.
The investigation uncovered evidence suggesting a pattern of behavior across multiple victims. Prosecutors allege Høiby filmed some assaults, with digital evidence forming part of the case. His previous admissions regarding substance-fueled violence against a girlfriend while under the influence of cocaine and alcohol are noted in charging documents.
This case carries significant implications for Norway’s monarchy, though the royal palace has distanced itself, stating the matter is ‘for the courts to decide.’ Prosecutor Henriksbø emphasized that Høiby’s royal connections won’t affect judicial treatment, noting he’ll receive neither special leniency nor harsher punishment. The scandal has nonetheless sparked national conversations about privilege and accountability.
Høiby’s defense team acknowledges some lesser charges but vehemently denies all sexual assault allegations. His lawyer, Ellen Holager Andenæs, maintains his innocence regarding rape claims while confirming he takes the accusations seriously. Høiby currently remains free pending trial after prosecutors determined no immediate detention was necessary.
The trial is scheduled to begin in mid-January 2026 at an Oslo court and is expected to last approximately six weeks. If convicted on the most serious charges, Høiby faces up to 10 years imprisonment. The proceedings will be closely watched internationally given the defendant’s unique position in European royalty.
Beyond the legal consequences, this case may prompt institutional reflection in Norway regarding how high-profile defendants are handled and protections for victims of sexual violence. The outcome could influence future cases involving public figures while testing Norway’s judicial independence in politically sensitive matters.
