The publication of the tribunal’s written reasons brings the Markéta Vondroušová case into sharper focus. No prohibited substance was found. Tests conducted on December 7, 2025, four days after the incident, and again on May 3, 2026, were both negative. Nor did the tribunal disqualify the results she recorded between the refusal and the start of her suspension.
The version that best fits the evidence is not one of a player trying to escape a test. Nor, in all likelihood, is it the story of someone who had completely lost the ability to understand what was happening or make a decision. It is the story of an argument.
Vondroušová was alone at home when an unfamiliar woman arrived at around eight in the evening. She became convinced that the test was unauthorised because her ADAMS whereabouts window was set for seven in the morning. She felt that her privacy was being invaded and became angry. Believing she was in the right, she refused the test. Within minutes, a dispute over the way the test was being conducted had turned into an anti-doping violation carrying a four-year ban.
Not an attempt to escape, but a refusal on principle
The most revealing evidence is a message Vondroušová sent her boyfriend at 8.05 p.m., while the officer was still at the intercom: “So like here is ringing some cunt from the doping.”
In other words, someone from anti-doping was ringing her bell and she was furious about it. This is the language of someone who believes the other person has no right to be doing what she is doing.
Later that evening, Vondroušová posted a photograph of the officer on Instagram and publicly set out her position. She said that she complied every day with her declared whereabouts hour, but regarded a test at 8.15 p.m. as a serious invasion of her privacy. She tagged the WTA, ITF and WADA, adding that the rules should apply to those enforcing them as well.
The tribunal treated the post, together with the messages sent at the time, as evidence that the real issue was not the woman’s identity but the timing of the test.
At paragraph 102, the tribunal finds that Vondroušová knew she had been asked to submit to a test and deliberately refused because she mistakenly believed that she could be tested only during her designated 60-minute window. At paragraph 103, it therefore classifies the refusal as intentional.
In this context, “intentional” does not mean that she was trying to conceal the presence of a prohibited substance. It means that she understood what was being asked of her and consciously chose not to provide the sample.
The rules nevertheless treat that conduct extremely seriously. Article 2.3 does not require proof of an intention to conceal doping. A deliberate refusal following valid notification, without compelling justification, is enough.
The tribunal preferred the officer’s account, but did not accuse Vondroušová of lying
The two women gave different accounts of what happened.
The officer said that she rang the intercom, introduced herself as an official conducting a test on behalf of the ITF, explained that testing could take place outside the athlete’s ADAMS window and offered to wait for two or three hours.
Vondroušová had initially claimed that the intercom was rung repeatedly, perhaps as many as 15 times, and that the woman had failed to identify herself properly.
The tribunal regarded the officer as an honest, straightforward and broadly consistent witness. It also made clear, however, that it did not believe Vondroušová had deliberately given false evidence.
Instead, it noted that the player’s account moved closer to the officer’s version during the hearing. She no longer categorically denied that there had been a second conversation over the intercom, did not give a precise number of times the bell had rung and acknowledged that the woman was outside the building when she came downstairs with her dog.
On that basis, the panel preferred the DCO’s evidence.
This supports the view that the incident was an argument, rather than an attempt to evade the test or the behaviour of someone in a state of complete confusion. Vondroušová called her agent, messaged her boyfriend, went downstairs with her dog, spoke to the officer, signed the form, photographed it, sent it to her agent and shortly afterwards published a detailed Instagram story.
These were organised actions consistent with a protest. She believed the evening test was unlawful and wanted to challenge it.
Vondroušová was wrong about the ADAMS window
There is little room for disagreement on the central regulatory issue.
The daily 60-minute window does not define the only time during which an athlete may be tested. It guarantees a particular time and place at which the athlete must be available and where an absence may be recorded as a missed test. It does not prevent anti-doping authorities from carrying out out-of-competition testing at other times or in other places.
The instructions given to the officer expressly stated that the test did not have to take place during the player’s 60-minute window. Vondroušová was also an experienced athlete who had previously received at least 83 test notifications. During the proceedings, she acknowledged that she knew athletes could be tested at any time.
Under the TADP, the correct course would have been to provide the sample, place her objections on the record and then challenge the timing, the identification procedure or the conduct of the test afterwards. Believing that she was in the right did not make the refusal lawful.
But saying that Vondroušová was wrong about the ADAMS window does not mean giving anti-doping authorities carte blanche.
A professional athlete accepts a substantial intrusion into her private life in order to protect the integrity of the sport. She does not, however, give up the right to know who is turning up at her home, to check that person’s credentials or to be treated in accordance with clear and rigorous procedures.
The officer did not show her credentials
This is the most troubling procedural issue in the decision.
The tribunal found that the officer was properly authorised. She had received a valid mission order, carried an identification card and had a copy of the authorisation letter on her iPad.
But the question was not merely whether she was authorised in principle. It was whether she demonstrated that authority to the person whose home she wanted to enter and from whom she was requesting blood and urine samples.
Paragraph 83 does not find that the officer showed either her identification or the authorisation letter. She did not do so because Vondroušová had not agreed to undergo the test.
The tribunal therefore accepts a hypothetical reconstruction: the DCO had the documents with her and, in line with her usual practice, would have shown them before entering the apartment.
Identification, however, should not be something an athlete receives only after agreeing to the test. It should be a preliminary requirement, particularly when an unfamiliar person arrives at a private home in the evening.
The more intrusive the power being exercised, the stricter the procedure authorising it should be. That is especially true when the authorities are insisting on strict compliance while seeking a four-year ban.
The defence argued that the duty to provide proper identification rested entirely with the officer. It could not be shifted onto the player by expecting her to ask for an identification card, an authorisation letter or a security code.
The tribunal rejected that argument. It found that Vondroušová had understood that the woman was a tester and that any departures from the international standards did not automatically invalidate the evidence establishing an Article 2.3 violation.
Within the narrow logic of anti-doping law, the conclusion hangs together. By ordinary standards of fairness and due process, it remains unsatisfactory.
The fact that Vondroušová had correctly worked out who the woman was did not make the duty to identify herself unnecessary. The officer’s underlying authority does not resolve the problem with the way that authority was exercised.
The form was outdated and referred to a two-year ban
There was also a more concrete irregularity.
Paragraph 43 records that the officer completed an outdated form by hand. The document given to Vondroušová stated that refusing the test could lead to a two-year period of ineligibility. The applicable sanction for an intentional refusal was actually four years.
In the comments box, the officer wrote that the athlete would not undergo the test in the evening because her one-hour window was in the morning. Vondroušová signed the form without adding any comments, photographed it and left. Two minutes later, she told her agent that the situation was completely absurd.
Vondroušová does not claim that she consciously chose to risk two years rather than four. Even so, this is difficult to dismiss as a minor detail.
She was being required to make an immediate decision under threat of extremely serious consequences, while the official document placed in front of her described those very consequences inaccurately.
The decision never properly explains why the organisation’s mistake about the length of the sanction should be irrelevant when assessing the degree of fault of the person who signed the form. It is one of the clearest gaps in the tribunal’s reasoning.
The psychological defence did not hold up
Vondroušová argued that she suffered from generalised anxiety disorder and had experienced an acute stress reaction that impaired her cognitive and executive functioning. The defence sought to establish that submitting to the test had become mentally and morally impossible.
The tribunal did not deny that she was anxious and under stress. It noted, however, that the diagnoses had been made retrospectively, after the charge had been brought, and that there was no evidence of medical treatment in the days immediately surrounding the incident.
The defence witness the tribunal found most persuasive, Dr Philip Hopley, said that generalised anxiety and acute stress had significantly affected Vondroušová’s emotional stability, her perception of events and her decision-making.
The tribunal found, however, that he had not explained the extent to which those abilities had been impaired. None of the evidence it regarded as sufficiently reliable established a loss of rational judgement approaching the exceptional threshold required by the rules.
This part of the decision is fairly persuasive.
The defence tried to turn an impulsive and angry decision, probably influenced by anxiety, into a substantial inability to make a decision at all. The evidence produced at the time made such an extreme argument difficult to sustain.
But Vondroušová did not need to be completely incapable of understanding what she was doing for anxiety, isolation, a sense of intrusion, the evening timing and anger to reduce her degree of fault.
This is where the decision becomes much less convincing.
The tribunal acknowledges the circumstances and then strips them of any significance
In the final part of the decision, the panel accepts that Vondroušová made a “decision in the heat of the moment”, while under stress and anxiety, with enormous consequences.
It also notes that she had no previous anti-doping violations and had enjoyed a highly successful career.
That is almost an exact description of an argument that got out of hand. It was not a plan, but a bad decision made in a matter of minutes by someone who believed she was defending her home and her privacy.
Immediately after acknowledging this, however, the tribunal says it cannot consider whether the sanction is fair.
At paragraph 149, it states that there is “no scope for any arguments of proportionality”. The four-year ban is therefore treated as an essentially automatic consequence of classifying the conduct as an intentional refusal.
This is the central weakness of the decision.
The tribunal recognises every unusual feature of the case but does not meaningfully weigh them. It accepts that Vondroušová was anxious, acted impulsively, had no previous violations and faced the effective destruction of her career. It also records that the form was outdated and that the officer’s credentials were not shown. It then concludes that none of those factors can open the door to an assessment of proportionality.
There is an understandable reason why the anti-doping system treats refusal severely: a light penalty could encourage someone who had taken a prohibited substance to refuse the test.
But that general principle should not rule out a distinction between an athlete who refuses in order to conceal doping and one who refuses during a dispute over the way the test is being conducted—mistaken about the law, but not acting with the purpose of evading detection.
Privacy and personal rights are not favours granted to athletes
The defence also relied on the right to respect for private life under Article 8 of the European Convention on Human Rights, together with the principle that restrictions imposed by anti-doping rules must be proportionate.
The tribunal replied that its role was not to decide whether out-of-competition testing was desirable, but only whether Vondroušová had complied with the TADP.
That leaves the underlying issue unresolved.
Anti-doping does not operate outside the normal rules of civil society. The fact that an athlete must be available for testing at any time does not mean that the authorities may disregard identification, security in the home, accurate information or basic respect for the individual.
On this point, it is possible to side with the athlete while still accepting that she committed the violation.
Defending Vondroušová’s privacy does not mean claiming that she had the right to refuse the test. It means insisting that the power to arrive at someone’s home and demand biological samples must be exercised with at least as much procedural care as is demanded of the athlete.
The responsibilities are not equal.
Vondroušová had only a few minutes to assess a situation she had never previously encountered in that form. The officer and the anti-doping organisation were professionals whose job was to deal with precisely that kind of situation. Yet the credentials were not shown and a form stating the wrong sanction was used.
The four-year ban remains open to question
The written reasons strengthen the finding that an anti-doping violation occurred.
Vondroušová knew that the woman was there to conduct a test, understood that she was being asked to provide a sample and refused because she believed the timing made the request unlawful.
But the same written reasons do not make the four-year ban inevitable.
The officer did not show her identification or authorisation. The tribunal merely says that she would have done so later. The form was outdated and referred to a two-year sanction. The test was attempted in the evening at the private home of a player who was alone. The panel itself acknowledges stress, anxiety, impulsiveness and the absence of any previous violation, yet treats proportionality as outside the scope of its assessment.
Vondroušová was wrong to believe that the ADAMS window entitled her to refuse. But she was entitled to expect a flawless procedure, immediate identification and accurate information.
Anti-doping authorities are allowed to intrude deeply into athletes’ private lives because they are responsible for protecting the integrity of sport. That does not mean their powers override every other right.
The tribunal explains convincingly why a violation occurred. It is far less convincing in explaining why, within a range of two to four years, the maximum sanction was necessary—or why the case called for the harshest available outcome rather than a common-sense one.
