The Sun Yang Case: History and Substance
This case is arguably one of the the most high-profile and procedurally complex sagas in the history of international sports law. What began as a midnight dispute over a blood sample evolved into a four-year and four decision legal marathon that tested the boundaries of arbitrator impartiality, the “duty of curiosity” regarding social media, and the rigid application of the “provide first, protest later” rule.
The case originated from an out-of-competition anti-doping test on September 4-5, 2018, at Sun Yang’s residence in Zhejiang, China. During the mission conducted by IDTM (on behalf of FINA), a dispute arose regarding the accreditation and credentials of the testing personnel (the Doping Control Officer, Blood Collection Assistant, and Doping Control Assistant).
As the dispute escalated, Sun Yang and his security team prevented the samples from being taken away. Most notoriously, a blood vial that had already been collected was smashed with a hammer by Sun’s security detail to ensure it could not be tested.
Initial Ruling (FINA) In January 2019, the FINA Doping Panel issued a decision concluding that the testing mission was invalid due to improper credentials. While they criticized Sun Yang for a “huge gamble,” they found no Anti-Doping Rule Violation (ADRV). The World Anti-Doping Agency (WADA) disagreed and appealed to the Court of Arbitration for Sport (CAS).
The First CAS Award (Feb 28, 2020)
- The Ruling: The Panel found Sun Yang guilty of “Tampering or Attempted Tampering” (Art. 2.5 FINA DC).
- Key Findings: CAS held that even if an athlete doubts the credentials of testers, they must provide the sample and protest later (the “provide first, complain later” principle). Smashed vials constituted a clear ADRV.
- Sanction: Because this was Sun’s second ADRV (following a 2014 suspension), the Panel imposed the maximum 8-year ban.
The First Swiss Federal Tribunal (SFT) Decision (Dec 22, 2020)
- The Ruling: The SFT annulled the 8-year ban and ordered a re-trial.
- The Reason: After the first award, Sun’s legal team discovered tweets by the CAS Panel President, Franco Frattini, containing “violent expressions” and “racist slurs” directed at Chinese nationals.
- Legal Significance: The SFT ruled these tweets created “objectively justified doubts” regarding the arbitrator’s impartiality. This was a rare instance of the SFT setting aside a CAS award on the grounds of procedural irregularity (improperly constituted tribunal).
The Second CAS Award (June 22, 2021)
- The Ruling: A new CAS panel reached the same substantive conclusion—Sun Yang committed an ADRV—but reduced the sanction.
- Key Findings: The new panel again rejected Sun’s excuses for the hammer incident. However, between the first and second hearings, the 2021 WADA Code had come into effect.
- Sanction: Under the new “lex mitior” (more lenient law) principle, the panel applied the 2021 Code’s rules for multiple violations. It calculated a 4-year and 3-month ban, backdated to the original February 2020 decision.
The Second SFT Decision (Feb 14, 2022)
- The Ruling: The SFT dismissed Sun Yang’s second appeal in its entirety.
- Key Findings: The court found no further evidence of bias or violation of the “right to be heard.” It emphasized that its power to review CAS decisions is extremely limited (restricted to public policy/procedural issues).
- The Result: The 4-year and 3-month ban became final, effectively excluding Sun Yang from the Tokyo 2020 Olympics.
What This Means for the Law
- Arbitrator Neutrality & Social Media: The case is the leading authority on the “duty of curiosity” for parties and the “duty of disclosure” for arbitrators. Social media history can and will be used to challenge awards.
- Strict Compliance with Testing: It reinforces the rule that athletes cannot unilaterally terminate a test based on procedural disagreements. The “provide first, protest later” rule is absolute.
- Lex Mitior in Sports Law: It demonstrates how changes in the WADA Code can retroactively benefit athletes in pending cases, even if the underlying violation is proven.
The Sun Yang saga reminds us that while the “provide first, protest later” rule protects the integrity of testing, the “impartiality of the arbitrator” protects the integrity of the law. Even when the facts seem insurmountable, procedural fairness remains the ultimate check on arbitral power.
