Norwegian court keeps crown princess's son in custody despite mother's terminal illness

Crown Princess Mette-Marit faces a life-threatening illness requiring lung transplant; her son remains in custody despite family hardship during her medical crisis.
Sitting inside when I know Mum is so sick is unbearable
Høiby's words to the district court, expressing the collision between his legal detention and his mother's terminal illness.

In Norway, a court of appeals has determined that Marius Borg Høiby — son of Crown Princess Mette-Marit, raised within the royal household but not of it — must remain in custody until the verdict in his rape trial is delivered on Monday. The ruling came despite the extraordinary circumstance of his mother's life-threatening pulmonary fibrosis and her recent placement on a lung transplant waiting list. It is a moment that asks an ancient question: whether the weight of private suffering can or should alter the course of public justice.

  • A 29-year-old man faces 40 criminal charges — including four counts of rape — with prosecutors seeking nearly eight years in prison, making the stakes of Monday's verdict severe.
  • His mother, Crown Princess Mette-Marit, has been placed on a lung transplant waiting list after a sharp deterioration in her condition, creating a family crisis that collided directly with the custody dispute.
  • A lower court briefly granted his release on compassionate grounds, but the appeals court swiftly reversed the decision, ruling the risk of reoffending remained unchanged and that contact with a key complainant was a real danger.
  • His own words — 'sitting inside when I know Mum is so sick is unbearable' — captured the human anguish at the center of a case that has drawn intense public scrutiny.
  • The Norwegian royal family now faces converging pressures: a son in custody, a gravely ill crown princess, and lingering questions about her past friendship with Jeffrey Epstein.

On Wednesday, a Norwegian appeals court ruled that Marius Borg Høiby would remain in jail until Monday's verdict in his rape trial, overturning a lower court decision that had briefly granted him release on compassionate grounds. The 29-year-old, raised within the royal family though not a member of it, faces 40 criminal charges including four counts of rape. Prosecutors are seeking a sentence of seven years and seven months. He denies the rape allegations but has admitted to lesser offenses.

The custody dispute has unfolded against a painful family backdrop. His mother, Crown Princess Mette-Marit, is 52 and living with pulmonary fibrosis — a progressive, incurable lung disease. Last week, her doctors placed her on a transplant waiting list after her condition worsened significantly in recent months. When the district court briefly ordered his release, Høiby told the judge that being confined while knowing his mother was so ill was unbearable. He was allowed out briefly to attend a meeting with her specialist at the family estate, but the appeals court determined the risk of him resuming contact with the woman at the center of the original allegations remained real and unchanged.

The case has placed the Norwegian royal family under an unforgiving light. Crown Prince Haakon and Princess Mette-Marit visited Høiby in prison after news of the transplant listing became public, and their two children visited him hours after their mother was hospitalized. The family has also faced separate scrutiny over revelations that the crown princess once maintained a years-long friendship with Jeffrey Epstein. When asked about her daughter-in-law's health during a royal engagement, Queen Sonja offered only four words: 'the situation is serious.'

Høiby will remain in custody until the verdict is delivered Monday — separated from his family at what may prove to be a defining moment in his mother's illness.

On Wednesday, a Norwegian appeals court made a decision that will keep Marius Borg Høiby in jail through Monday's verdict in his rape trial, rejecting arguments that his mother's deteriorating health warranted his release. The 29-year-old, who is not himself a member of the royal family but was raised within it, had won a temporary reprieve from a lower court just two days earlier. That district court had ordered his release, reasoning that the risk of him reoffending was marginal and that continued detention would be disproportionately harsh. The appeals panel disagreed, finding the danger of further crimes remained essentially unchanged from their assessment in May.

Høiby has been held in custody since early February, facing 40 criminal charges that include four counts of rape. Prosecutors are asking for a sentence of seven years and seven months. The rape allegations involve women who were either asleep or unable to consent after consensual sexual activity had occurred—one count involves intercourse, three involve sexual assault. He denies the rape charges but has admitted to lesser offenses including drug possession and traffic violations. The trial has also examined allegations of violence, threats, and abusive behavior in a relationship, all of which he contests.

The timing of the custody dispute has collided with a family crisis. His mother, Crown Princess Mette-Marit, is 52 and living with pulmonary fibrosis, a rare and incurable lung disease that causes scarring and makes breathing progressively harder. Last week, doctors placed her on a waiting list for a lung transplant after determining her condition had sharply worsened in recent months. The standard for transplant candidacy is that a patient is expected to have roughly one year remaining. Her specialist at Oslo University Hospital confirmed publicly that her health had significantly deteriorated over the past three months.

Høiby's legal team had argued that he needed to be near his mother during this medical emergency. When the district court granted his release on Monday, he told the judge: "Sitting inside when I know Mum is so sick is unbearable." That same day, he was briefly allowed out of jail to attend a meeting with his mother's doctor at the family's estate outside Oslo. But the appeals court, ruling Wednesday, determined there was an obvious risk he would resume contact with the woman from the upmarket Frogner neighborhood of Oslo—the person at the center of the original allegations that led to his arrest in August 2024. His defense lawyer Ellen Holager Andenæs told Norwegian media the decision was deeply disappointing and expressed sympathy for her client's position.

The case has cast a difficult spotlight on the Norwegian royal family at a moment of genuine vulnerability. Crown Prince Haakon and Princess Mette-Marit visited Høiby in prison last Sunday after news of her transplant listing became public. Their two children, Princess Ingrid Alexandra and Prince Sverre Magnus, visited him hours after their mother was hospitalized. The royal family has also faced separate scrutiny following revelations that the crown princess had maintained a three-year friendship with Jeffrey Epstein, the disgraced financier and convicted sex offender who died in jail in 2019. King Harald, 89, and Queen Sonja, 88, have largely avoided the crises engulfing the younger generation. When asked about the crown princess's health during a royal visit on Tuesday, the queen simply said "the situation is serious."

The verdict is expected Monday. Høiby will remain in custody until then, separated from his family during what may be a critical period in his mother's illness.

Why did the appeals court overturn the lower court's decision so quickly? What changed between Monday and Wednesday?

Model

Nothing changed in the facts about Høiby himself—the appeals court said the risk of reoffending was "virtually unchanged" from their May assessment. What they disagreed with was the lower court's judgment that detention had become disproportionate. They saw a concrete risk he'd contact the woman from Frogner again, and that was enough to keep him inside.

Inventor

But his mother is dying. Doesn't that matter legally?

Model

It matters enough that his lawyers argued it, and it mattered enough that the lower court listened. But the appeals court weighed it differently—they decided the legal risk outweighed the personal hardship. The law doesn't have a simple formula for that kind of collision.

Inventor

He's not even technically royal, is he?

Model

No. He was born before his mother married the heir to the throne, so he was raised in the family but never became part of it officially. That distinction might matter in some contexts, but it doesn't seem to have changed how the courts treated his case.

Inventor

What happens if the verdict comes down and he's convicted? Does he go straight back to prison?

Model

Almost certainly. He's already been in custody since February. A conviction on these charges—especially the rape counts—would almost certainly mean prison time. The prosecutors are asking for seven and a half years.

Inventor

And his mother—is there any chance she gets the transplant in time?

Model

That's the unknowable part. She's on the waiting list now, which means doctors think she has about a year. But lung transplants depend on donor availability, and her condition is already worsening fast. The family is in a genuinely precarious position.
