The Court Of Arbitration For Sport (CAS) Registers The Urgent Appeal Filed By Dayana Yastremska

Press Release

27th January 2020

The Court of Arbitration for Sport (CAS) has registered the appeal filed by Ukrainian tennis player Dayana Yastremska against the International Tennis Federation (ITF) in relation to the decision taken by the ITF Independent Tribunal on 22 January 2021 (the Challenged Decision), which rejected the application made by Dayana Yastremska to lift her provisional suspension.

In her appeal to CAS, Ms Yastremska seeks to have the Challenged Decision set aside and her provisional suspension lifted in order to be able to participate in the 2021 Australian Open tennis tournament.

The CAS arbitration has commenced and the parties have agreed to an expedited procedure in order to enable a sole arbitrator to issue a final decision by 3 February 2021.

A urine sample provided by Ms Yastremska on 24 November 2020 was found to contain a metabolite of mesterolone, a banned substance on the WADA Prohibited List. Following the analysis of the B Sample, which confirmed the finding for the A Sample, Ms Yastremska was provisionally suspended by the ITF with effect as from 7 January 2021. On 16 January 2021, Ms Yastremska applied to lift the provisional suspension but the Chair of the ITF Independent Tribunal rejected the application and maintained the provisional suspension. The grounds for the Challenged Decision were notified to Ms Yastremska on 24 January 2021.
