Marius Borg Høiby, the eldest son of Norway’s Crown Princess Mette-Marit, was sentenced to four years in prison on Monday [1].

The sentencing marks a significant legal blow to a member of the royal circle and brings public scrutiny to the Crown Princess's immediate family.

The court delivered the verdict on June 15, 2026 [2]. Høiby was convicted on two counts of rape [1]. While he faced four total rape charges, the court acquitted him of two of those counts [1].

Beyond the sexual assault convictions, the court also found Høiby guilty of assault, and abuse within a close relationship [1]. These combined charges led to the four-year prison term [1].

Legal proceedings took place in Norway, with reporting indicating the sentencing occurred in a district court [3]. The case has drawn international attention due to Høiby's relationship with the Norwegian royal family, though he does not hold a royal title himself.

The sentencing concludes a period of intense legal scrutiny for the son of the Crown Princess. The court's decision to impose a multi-year sentence reflects the severity of the convictions regarding both sexual violence and domestic abuse [1].

“Marius Borg Høiby was sentenced to four years in prison on Monday.”

The conviction and sentencing of Marius Borg Høiby creates a complex public relations challenge for the Norwegian monarchy. Because Høiby is the son of the Crown Princess but not a prince, the legal proceedings followed standard civilian court protocols rather than royal immunity or special tribunals. The outcome underscores the application of Norwegian law regardless of familial ties to the throne.
