However, the CAS decision may not be the end of the matter. Reeb did not take any questions.
That's why the CAS decision, which upheld the IOC's right to decide who could compete at its biannual party, was merely a brief respite in the never-ending war on doping.
The appellants had asked CAS to overturn a decision by the International Olympic Committee (IOC) not to invite them over doping concerns, meaning they won't be joining the 150 competitors cleared to compete as "Olympic Athletes from Russia" (OAR).
The International Olympic Committee (IOC) past year banned Russian Federation from Pyeongchang for what it called the "systematic manipulation" of the anti-doping system at the 2014 Sochi Games.
The Court of Arbitration for Sport has affirmed a decision that 47 Russian athletes and coaches should not be allowed to participate in the Winter Olympics, weighing in on the matter with just hours to go before Pyeongchang holds its opening ceremony for almost 3,000 athletes from around the world.
The Court of Arbitration for Sport heard the case of the 45 Russian athletes - including numerous medal contenders - and two coaches on Thursday.
On Friday, Jim Walden, the lawyer of whistleblower Grigory Rodchenkov, the former head of the Russian anti-doping lab who has fled the country and lives in hiding in the United States, said IOC President Thomas Bach should resign.
South Korea-born Ahn is the most decorated short-track speedskater in Olympic history with six gold medals.
There were no current Russian Olympians at the opening - 168 will compete in Pyeongchang - but organizers plan to host any medalists later for media events.
Olympic skeleton bronze medallist Elena Nikitina will not take part here either.

Turkey, Iran violating global law in Syria
On Monday, Iran urged Turkey to halt the Afrin operation, saying it breached Syrian sovereignty and would increase tension. Turkish Foreign Minister Mevlut Cavusoglu paid a surprise visit to the Iranian capital Tehran on Wednesday.
Investigations revealed an elaborate ploy where tainted Russian urine samples were switched with clean ones overnight using a "mousehole" in the wall of the Sochi anti-doping laboratory.
After two days of hearings, the CAS panel ruled that the commissions that evaluated whether Russian applicants were eligible did not act in a "discriminatory, arbitrary or unfair manner".
CAS also concluded there was no evidence the two International Olympic Committee panels "improperly exercised their discretion".
The IOC and the World Anti-Doping Agency welcomed the decision.
"By this light show in front of the headquarters of WADA we want to tell the whole world that the only doping among the Russian Olympic team is our support and love", they said.
Nadezhda Sergeeva's bobsled training outfit says a lot about what life will be like for an "Olympic Athlete from Russian Federation".
Russian Deputy Prime Minister Vitaly Mutko said on Friday the CAS ruling was understandable but disappointing.
The IOC had been taking nothing for granted on Friday following a separate CAS ruling earlier this month which saw it defeated.
The hopes of 47 Russian athletes and coaches were dashed merely hours before the Winter Olympics began, when the Court of Arbitration for Sport (CAS) denied their appeal to participate in the competitions.
Stephen Hess, an global sports lawyer based in Colorado Springs, Colorado, said the decision was a victory for the IOC.
