After the 2002 Winter Olympics in Salt Lake City, Utah, the ISU implemented sweeping changes to many of its events. In one of the short track speed skating events, Apolo Anton Ohno was awarded the gold medal after the disqualification of Kim Dong-Sung. Although the South Korean delegation protested the decision, ISU rules did not allow for a review of the official's call. Several months later, the ISU approved the use of video replay, when available, to review referee decisions. The rules for judging figure skating were also overhauled as a direct result of the 2002 Olympic Winter Games figure skating scandal. According to Ottavio Cinquanta, former president of the ISU, "'Something was wrong there,' ... 'Not just the individual but also the system. It existed for 70 years. Now we are trying to replace one system with another.'" A new judging system for figure skating took effect in 2005, replacing the 6.0 system of "perfect" scores and instead giving points for various technical elements.
