A ruling from a Norwegian district court has been thrown out over suspicions involving artificial intelligence. The Gulating Court of Appeal decided to overturn the lower court's judgment after doubts emerged about how it had been written. According to the appeal court, there is reason to believe the ruling may have been drafted with the help of AI. The decision effectively cancels the original judgment. Cases that are reopened in this way go back to the district court for a fresh consideration. The episode has put the way Norwegian judges draft their rulings under unusual scrutiny. It remains unclear whether the source of the suspect text will be explained publicly.
