Which major competitions do you think were the most poorly judged?
Two competitions come to mind for me: 2001 Worlds, and 2002 Olympics.
The 2001 Worlds' pairs and ice dance competition results were blatantly incorrect, in my opinion. Berezhnaya/Sikharulidze and Anissina/Peizerat should have almost unanimously won in place of Sale/Pelletier and Fusar-Poli/Margaglio. Hughes placing over Butyrskaya also was not the best judging, but I didn't think it was that big of a difference.
In the 2002 Olympics, the pairs' competition was a source of controversy. I thought both B/S and S/P were roughly equal that night, so it could have gone either way. But giving two sets of gold medals seriously discredited the sport and the scoring system, which I like a lot more than the current one. Maybe that has nothing to do with judging and could be irrelevant.
The ice dance, in my opinion, had the biggest 'scandal'. There was no doubt in my mind that Drobiazko/Vanagas should have been at least 3rd, with Bourne/Kraatz 4th and Fusar-Poli/Margaglio 5th. The ladies' competition was also poorly judged, although a lot of people might disagree with me about who should have won. I would have had Slutskaya the overall winner, since she should have had the best short program and 2nd best freeskate. Hughes was also overmarked in the short.
