Overview
- The independent tribunal announced its ruling on Monday, June 22, 2026, and imposed a four-year ban after finding Vondrousova offered “no compelling justification” for not providing a sample to a Doping Control Officer at her Prague home in December 2025.
- Under tennis anti-doping rules the starting sanction for an active refusal equals that for a positive test, which is why the tribunal handed the maximum four-year suspension rather than a shorter penalty.
- Vondrousova told the hearing and posted publicly that acute stress, diagnosed anxiety and fears for her safety influenced her refusal, and she says a control test three days after the incident was negative.
- The International Tennis Integrity Agency defended its testing practices, saying officers carry ID, match witness gender to players and use unpredictability to protect fair competition, while offering wellbeing support and promising written reasons for the ruling.
- Vondrousova can appeal to the Court of Arbitration for Sport, a move that could take months and will determine whether the ban stands, a decision that would effectively sideline a recent Wimbledon champion through what would have been prime competitive years.
