The case centers on Bernardo Segura, a racewalker disqualified after winning the 20km walk at the 2000 Sydney Olympics due to three rule infractions, the last occurring four minutes before the finish. Segura was notified of his disqualification 15 minutes after completing the race, leading him to appeal to the Court of Arbitration for Sport (CAS), arguing the delay invalidated the decision. The International Amateur Athletic Federation (IAAF) countered that CAS lacked jurisdiction to overturn on-field officiating decisions unless bad faith was proven and emphasized that reinstating Segura would unfairly penalize other athletes. The CAS panel, applying its ad hoc Rules and Swiss law, focused on the procedural aspects of the disqualification rather than the infractions themselves. Racewalking rules require judges to issue warnings for infractions, with disqualification following three warnings from different judges. While athletes are not obligated to monitor warnings, the Chief Judge must inform them of disqualification immediately after the race if impractical during the event. The panel acknowledged Segura might not have seen some warnings but found the Chief Judge’s delay justified due to handling another disqualification. It stressed that CAS does not review factual determinations of officials without evidence of bad faith, which was absent here. The panel dismissed Segura’s appeal, upholding the disqualification and clarifying that even if notification was delayed, reinstatement would unfairly affect other competitors. The decision reinforced that CAS does not second-guess technical judgments of officials unless procedural violations or misconduct are proven. The ruling maintained the final standings, with Korzeniowski, Hernández, and Andreyev retaining their medals. The case highlighted the balance between procedural fairness and the integrity of competitive results, emphasizing the importance of respecting on-field officiating decisions unless clear misconduct is demonstrated. The Panel concluded that the IAAF acted reasonably under the circumstances, and Segura’s disqualification was valid.
