Høiby is the son of Crown Princess Mette-Marit from a previous relationship and is not in the line of succession. Crown Prince Haakon expressed sympathy for those affected and emphasized trust in the rule of law. The Royal House and Oslo District Court did not immediately comment further.
Separately, the Crown Princess has been placed on the waiting list for a lung transplant after a deterioration of chronic pulmonary fibrosis, first announced in 2018. Royal sources say her condition has worsened and she has recently used a nasal cannula; medical experts described the progression as serious.
