Marius Borg Høiby, the son of Crown Princess Mette-Marit of Norway, remains in custody at Oslo Prison as legal proceedings continue regarding his alleged involvement in 40 criminal offenses. While his defense team has petitioned for his release to house arrest at Skaugum under the supervision of the Norwegian Correctional Service, the Oslo District Court has maintained his detention, citing a risk of recidivism and ongoing concerns regarding threats and violence against a complainant.
Legal Status and Custody Challenges
The legal situation for Marius Borg Høiby remains complex as he awaits a verdict. According to reports from May 6, 2026, Høiby has requested to serve the remainder of his remand period at his residence on the Skaugum estate while wearing an electronic monitor. His defense attorney, René Ibsen, stated to NTB that the Norwegian Correctional Service has already approved the residence for this purpose.
Despite these efforts, the Oslo District Court has repeatedly denied requests for release. The court’s primary justification for continued detention is the risk of reoffending, particularly regarding alleged violations of restraining orders and threats directed at the complainant known as the “Frogner woman.” Høiby was originally remanded on February 2, 2026, following accusations of bodily harm, threats involving a knife, and breaches of a restraining order.
The legal framework allowing for detention with an electronic monitoring device is a relatively recent addition to the Norwegian justice system, having been implemented in August 2025.
The Scope of the Charges
The trial against Høiby, which concluded on March 19, 2026, involves a significant volume of criminal allegations. Prosecutors have formally charged him with 40 distinct offenses. Among these, the most severe include allegations of “sovevoldtekt” (rape while the victim is asleep) involving four women, as well as charges related to domestic abuse.
The prosecution has requested a sentence of seven years and seven months in prison. A verdict is expected to be delivered by the Oslo District Court in June 2026. Throughout the trial, the court has consistently upheld the prosecution’s argument that Høiby should remain in custody until the final judgment is rendered.
Public and Political Discourse
The case has sparked broader debate within Norwegian society regarding drug policy and social norms. Trygve Slagsvold Vedum, leader of the Senterpartiet (Centre Party), publicly characterized the trial as a “horror example” of the consequences of what he describes as a “naive” drug policy. Speaking to Dagbladet in April 2026, Vedum noted that the testimony provided during the trial revealed frequent use of cocaine and other substances among those involved.
Vedum argued that the normalization of drug use within these social circles lowers the threshold for “limitless behavior.” He emphasized that while Høiby’s personal struggles are a matter for the court to decide, the case serves as a warning about the societal impact of drug prevalence. Høiby himself has been open about his personal struggle with substance abuse during the legal proceedings.
