Overview

• The CAS ruling overturns the provisional suspension and rejects WADA’s bid for a default four-year ban, fully restoring Thibus’s competitive status.
• Former partner Race Imboden admitted to using Ostarine for a modeling career and provided the basis for the contamination defense.
• Thibus tested positive in January 2024 but was cleared by an FIE tribunal, enabling her to compete in Paris where she did not podium.
• The decision rests on expert studies showing that repeated kissing could deposit measurable Ostarine traces in saliva sufficient to trigger a positive test.
• The landmark case is expected to prompt revisions to anti-doping regulations for handling unintended contamination scenarios.
