The Korean Sport Olympic Committee barred him from competing in the 2016 Olympic Games, even though his 18-month suspension for a positive doping test in 2014 has expired.
The appeal involves a KSOC rule that forbids athletes from competing for any national team for 3 years after a doping suspension.
Park is seeking an urgent ruling by July 8th, the cut-off date for selection to the Korean Olympic team.
While the grounds for the appeal wasn’t specifically stated, the appeal is likely on similar grounds to a 2011 appeal by the United States Olympic Committee (USOC). At the time, the USOC was appealing on behalf of track athlete LaShawn Merritt and fighting a rule by the International Olympic Committee (IOC) that would prevent any athlete with a doping ban of longer than 6 months to compete at the next Olympic Games.
The CAS at the time ruled that this new ‘Rule 45″ put in place by the IOC amounted to double sanction by punishing an athlete twice for one violation. While at the time the CAS commented that their objection wasn’t one on philosophical grounds, but rather that by the rules of the World Anti-Doping Code (which both the USOC and IOC signed), a second punishment was not allowed. It was suggested that the IOC instead of adding Rule 45 to its own charter instead make a push to have the World Anti-Doping Code amended.
No such amendment has come into effect since.
