Mr. Leeper plans to immediately appeal this decision to the Court of Arbitration for Sport (CAS).
Relying entirely on evidence and arguments that discriminate against Black athletes of African descent, the World Athletics-appointed Panel ruled that World Athletics had shown that Mr. Leeper's prostheses provided him "with an overall competitive advantage over any athlete not using such aids," and thus ruled Mr. Leeper cannot use those prostheses in any events sanctioned by World Athletics. The Panel's decision included no real scientific examination of Black athletes, and relied on the MASH standards, which have no application outside of the context of para-athletics and are themselves based on data that excluded Black athletes completely. Shockingly, World Athletics applied the MASH standards while simultaneously acknowledging that they are derived from studies done solely with Caucasian and Asian subjects, which excluded any subjects of African descent, even though World Athletics' own experts have admitted that persons of African descent have different body proportions, including longer limbs, than individuals of Caucasian and Asian descent.
