In the early years, judges were invited by the host country and were often native. At the 1927 ladies' event in Oslo, Norway, three of the five judges were Norwegian; these three judges gave first place to Norwegian competitor Sonja Henie, while the Austrian and German judges placed defending champion Herma Szabo first. The controversial result stood, giving Henie her first world title, but the controversy led to the ISU introducing a new rule that allowed no more than one judge per country on the panel.
