South Korea's Tae Young Yang has filed an appeal to the Court of Arbitration for Sport challenging the result of the men's all-round gymnastics final.

Yang controversially lost out to USA's Paul Hamm but only because of a judging error which marked down the degree of difficulty on the parallel bars exercise.

The International Gymnastic Federation (FIG) have pleaded with Hamm to hand the medal back as a gesture of fair play, although the United States Olympic Committee have reacted angrily to the request and have insisted their man should keep his title.

The International Olympic Committee have also taken a dim view of the FIG's stance but Yang has now decided to pursue his claim with the ultimate sports arbitration body.

However, with neither party able to formulate their case before the end of the Games, the matter will be dealt with in Lausanne at a date still to be decided.
