A statement by the International Association of Athletics Federations (IAAF) on Friday said an appeal had been filed with CAS against the decision taken by the Russian Federation last month.
"The IAAF considers that the offense committed justifies a heavier sanction and requests that the athletes be declared ineligible for a period for four years," the statement said.
Two-time world 1,500-meter champion Tatyana Tomashova was one of the athletes banned by the Russian Federation after IAAF testers found that DNA from samples provided in out-of-competition tests in May last year did not match with samples at the subsequent world championships.
World indoor 1,500-meter champion Yelena Soboleva, distance runners Yulia Fomenko and Svetlana Cherkasova, European discus champion Darya Pishchalnikova, former hammer world record holder Gulfia Khanafeyeva and former world 5,000-meter champion Olga Yegorova were also banned.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
