Marius Borg Hoiby, the eldest son of Norway’s Crown Princess Mette-Marit, has been formally charged with multiple serious offenses including rape and domestic violence, prosecutors announced.
The 28-year-old faces a potential decade-long prison sentence if convicted on the most severe charges, according to Oslo state attorney Sturla Henriksboe.

Extensive Criminal Allegations
The prosecution has filed 32 separate charges against Hoiby, spanning a range of serious criminal conduct:
Sexual Assault Charges:
- One count of rape involving sexual intercourse
- Three additional counts of rape without intercourse
- Some of these alleged incidents were reportedly recorded on his mobile device
Violence and Threats:
- Making death threats against individuals
- Domestic abuse involving a former romantic partner
- Acts of violence directed at another former partner
Defense Strategy and Client Response
Hoiby’s defense attorney, Petar Sekulic, indicated that his client intends to pursue a mixed plea strategy when proceedings begin. While maintaining innocence on the most serious accusations, Hoiby plans to accept responsibility for certain lesser offenses.
“He does not agree with the claims regarding rape and domestic violence,” Sekulic stated, clarifying his client’s position on the primary charges.
Investigation Timeline and Legal Process
The charges result from an extensive year-long police investigation that culminated in Hoiby’s arrest in November 2024. During that time, he was detained for one week before being released pending trial.
Court proceedings are expected to commence as early as January, with prosecutors estimating the trial will require approximately six weeks to complete. Hoiby remains free while awaiting the start of his trial.

Official Responses
Both the prosecution and the Norwegian royal palace have emphasized that the legal system must run its course without interference.
“It’s up to the judges to decide if he is guilty,” prosecutor Henriksboe stated, underscoring the presumption of innocence that applies even in high-profile cases.
The royal palace maintained a similar stance, confirming that the courts would handle the matter independently and declining to provide additional commentary beyond acknowledging the legal proceedings.
Broader Implications
The case represents a significant challenge for the Norwegian royal family, as it involves serious criminal allegations against a member of the extended royal household. The outcome will likely be closely watched both domestically and internationally as it unfolds in the coming months.
