However, The IOC maintained that clean athletes have the right to participate in the Pyeongchang Winter Games as the "Olympic Athletes of Russian Federation".
IOC had banned Russian Federation from participating in the Pyeongyang Olympic Winter Games on charges of engaging in doping by 'manipulating the anti-doping system at the Sochi Games in 2014.
On Tuesday, 32 Russian athletes, including biathlete Anton Shipulin, cross-country skier Sergei Ustyugov and short-track speed-skater Viktor Ahn appealed their non-invitation at CAS.
Medvedev, meanwhile, argued the IOC "has trampled on the Olympic Charter and elementary principles of law" by refusing to invite the Russians who had been exonerated by CAS.
In addition to clearing the 28, CAS also lifted the life bans of another 11 Russians but barred them from competing at Pyeongchang.
Bach added the International Olympic Committee was "extremely worried" about how the sport was run and that the International Olympic Committee was prepared to make bold decisions.
The ozone layer continues to thin
Substitutes for the particularly harmful CFCs are less thinning for the ozone layer but are not neutral either. These substances contain chlorine and bromine which destroy the layer presented in the lower stratosphere.
International Olympic Committee president Thomas Bach said: "The absence of sanctions by Cas does not mean that you are entitled to receive an invitation from the International Olympic Committee because receiving this invitation is a privilege of clean Russian athletes".
Last week, 28 Russians had life bans from the Olympics overturned by CAS, prompting 15 of them to apply to take part in Pyeongchang.
The allegations were mostly based on claims by Grigory Rodchenkov, former head of the Moscow Anti-Doping laboratory, who fled Russian Federation in 2015 while facing criminal charges.
"We gave a new and young generation of Russian athletes, after having passed great scrutiny by the independent panel, the opportunity to be invited to participate in the Games and to be ambassadors for a clean sport", he said.
"We can not lose sight of the extent nor the scale of the efforts that Russian authorities and athletes engaged in to cheat the anti-doping system", it said. Thus, we call for stronger leadership from sport to protect clean athletes and their right to doping-free sport.
Another WADA commissioned report released in 2017 found that Russia's elaborate state-sponsored doping program involving 1,000 athletes in 30 sports produced at least 27 ill-gotten Olympic medals and undermined the integrity of two Olympic Games and several other major worldwide sports competitions over a four-year period. That means they will compete under the Olympic flag and wearing uniforms without national insignia.
Instead those athletes will be represented by the "Olympic Athlete from Russia" logo on their uniforms and the Olympic anthem will be used if they are to win any medals.
