What happens next, the Court of Arbitration for Sport has received an appeal from Marketa Vondrousova but has not scheduled a hearing. CAS confirmed to BBC Sport that the filing arrived, leaving the former Wimbledon champion in suspended limbo while the calendar for any hearing is fixed.
The 27-year-old was banned in June after the International Tennis Integrity Agency accused her of denying a doping control officer entry to her home during an out-of-competition test in December 2025. Her suspension is set to end on 21 June 2030.
Vondrousova has described her actions as driven by exhaustion, saying in April she was at "breaking point after months of physical and mental stress". She said she feared for her safety when an officer knocked at her door at 20:00 on 3 December, and claimed the visitor failed to identify themselves or follow "protocol". The player says she signed a refusal form after stepping outside to walk her dog.
A tribunal rejected that account as sufficient, finding she provided "no compelling justification" for refusing the test and declining requests to reduce the length of the ban. That ruling is central to the case CAS will review, and it frames the short-term legal fight around whether the tribunal erred in fact or procedure.
Vondrousova highlighted her clean record in a statement after the ban. "I have never doped, I have never had a positive test. Throughout my entire career I have undergone countless anti-doping controls and have always stepped on the court with a clear conscience," she said.
The suspension has halted a career that includes a 2023 Wimbledon title, a French Open final appearance, an Olympic silver medal and a peak ranking of world number six. She has not played since losing in the second round of the Adelaide International in January, and her ranking has fallen to 153rd, complicating any immediate return even if the ban is overturned.
The CAS timetable will determine whether Vondrousova can shorten the period away from competition, but for now the ban keeps her off the tour until June 2030 and forces a legal rematch over intent, procedure and the role of mental-health claims in anti-doping cases.
