Marketa Vondrousova, the 2023 Wimbledon champion, has been handed a four-year suspension for refusing to take a doping test on December 3, 2025. The International Tennis Integrity Agency (ITIA) released the full decision of the independent tribunal that reviewed her case on July 31.
The tribunal found that Vondrousova was penalized with the maximum sentence for her refusal to comply with the doping test procedures. She argued that the doping officer arrived outside the 60-minute window she had specified to the ITIA, failed to identify himself, and did not explain the consequences of her refusal.
Additionally, Vondrousova mentioned that she had been battling anxiety for a long time, and her mental state was poor at that moment, which affected her judgment.
ITIA Publishes Tribunal’s Findings on Vondrousova’s Suspension
Following the month-long deliberation, ITIA disclosed the tribunal’s ruling, which included members Grace Cheng, Cristy Cooper, and Lorraine Johnson. The tribunal acknowledged that the doping control officer arrived at Vondrousova’s residence around 8 PM, far beyond the declared hour of 7 AM to 8 AM.
However, ITIA maintained that doping tests can be conducted at any time between 6 AM and 11 PM, asserting that the athlete’s declared window is merely a guideline for ensuring they are home during that time.
Vondrousova stated she became frightened upon seeing an unfamiliar person at her home and contended that the officer had not properly identified himself nor adhered to established protocols. She also believed that a test conducted outside her declared timeframe was not permissible.
Conversely, ITIA claimed that the officer introduced himself and outlined the purpose of his visit, explaining that testing could happen outside the declared hour and that refusal to comply could lead to severe penalties.
Tribunal Concludes Vondrousova Acknowledged Doping Officer’s Visit
Based on WhatsApp messages where Vondrousova referred to the visitor as “the doping officer” and an Instagram Story expressing her objection to the testing time, the tribunal determined that she was aware of the officer’s identity.
Although Vondrousova signed a refusal form that was dated prior, the tribunal found this did not invalidate the notification. The tribunal accepted that she suffered from anxiety and was under significant stress but concluded that these issues did not hinder her ability to comply with testing obligations and did not impair her rational decision-making.
As a result, Vondrousova was sanctioned for her intentional refusal to provide samples and received a four-year suspension. Nevertheless, as she was tested again four days later with a negative result, the tribunal decided not to invalidate her results from December 2025 to June 2026.
The suspension officially commenced on June 22, 2026, and Vondrousova retains the right to appeal the decision to the Court of Arbitration for Sport (CAS). The complete ruling is available for consultation via the provided link.
