According to documents published by Aktuálně.cz and Aktuality, 2023 Wimbledon champion won a four-year ban on December 3, 2025, after an independent tribunal ruled she intentionally refused to submit a sample for an out-of-competition doping test. The sanction, which spans from June 22, 2026, to June 21, 2030, halts all participation in events authorized by the International Tennis Federation, WTA, ATP, and Grand Slams.
Independent Tribunal Rules on Competing Accounts of December 2025 Test
The case was evaluated by an independent tribunal consisting of Grace Cheng, Cristy Cooper, and Lorraine Johnson. According to the published documents, the panel reviewed conflicting testimonies regarding a visit by a doping control officer to the player’s residence. The control officer arrived at approximately 8:00 p.m. and first rang the doorbell at 8:05 p.m. This timing fell outside the player’s registered 60-minute whereabouts window, which had been logged between 7:00 a.m. and 8:00 a.m. that morning.
The International Testing Agency (ITIA) acknowledged that the visit occurred outside the designated morning window. However, according to official anti-doping regulations, athletes may be tested at any time between 6:00 a.m. and 11:00 p.m. The registered hourly slot indicates when an athlete must be available at a specific location, but it does not restrict testing to that hour alone, as noted in the findings.
Disputed Interactions and WhatsApp Messages Examined by Panel
During the evening visit, the player communicated via the home intercom that she did not understand why a test was being conducted outside her scheduled timeframe. She then contacted her agent, Enrico Molina, who also sought clarification from WTA personnel regarding testing rules. According to the defense, the control officer rang the intercom between eight and fifteen times before the player came outside with her dog.
Evidence presented to the tribunal included WhatsApp messages in which the player referred to the official as a woman “from doping,” alongside an Instagram post complaining about a test outside her declared interval. The tribunal concluded these communications proved she recognized the visitor’s official capacity. Although the defense cited long-term struggles with anxiety and high stress at the time of the incident, the tribunal found her psychological state did not prevent her from understanding her obligation to provide a sample.
Did you know? Registered testing pools require professional athletes to submit precise 60-minute windows for daily location tracking, though anti-doping organizations retain the authority to conduct unannounced tests throughout the day within permitted hours.
Sanction Terms and Subsequent Legal Steps
Following her refusal to complete the sample collection, the player signed a refusal form. She later stated she felt pressured and did not fully understand the consequences. Four days after the incident, she submitted to another doping control, which returned a negative result. Because of this subsequent negative test, the tribunal ruled against annulling her competitive results achieved between December 2025 and June 2026.
The four-year period of ineligibility prevents her from playing, training, or participating in any capacity within tennis organizations bound by the Tennis Anti-Doping Programme. Legal representatives for the Wimbledon champion confirmed plans to challenge the tribunal’s decision at the Court of Arbitration for Sport (CAS).
Frequently Asked Questions
Can tennis players be tested outside their registered whereabouts window?
Yes. According to anti-doping rules cited by the ITIA, athletes can be tested without advance notice between 6:00 a.m. and 11:00 p.m., regardless of their designated 60-minute location slot.
What are the consequences of refusing a doping test?
Refusing or failing to submit a sample without compelling justification is treated as an anti-doping rule violation, which carries a maximum standard penalty of a four-year suspension from professional competition.
Were the player’s previous tournament results canceled?
No. Because she passed a subsequent doping test four days after the incident, the tribunal decided not to invalidate her results from December 2025 through June 2026.
