Tobi Amusan has been exonerated by the Athletics Integrity Unity (AIU) of breaking an anti-doping regulation.
The decision was made public by AIU on Thursday.
The World Athletics organization announced that Amusan’s suspension has been revoked effective immediately.
The Nigerian athlete received a provisional suspension from AIU in July for allegedly “missing three tests in 12 months”.
Amusan’s case has been forwarded to a disciplinary tribunal, the AIU stated.
The world champion was consequently left off of the 26-person roster that the Athletics Federation of Nigeria (AFN) presented for the 2023 World Athletics Championships.
Similarly, her name on the World Athletics (WA) official list of athletes for the competition was accompanied by the caveat that her participation is based on the ruling on the case with AIU.
In the latest statement, AIU said a “majority decision” of the disciplinary tribunal ruled that Amusan “has not committed an anti-doping rule violation (ADRV) of three whereabouts failures within a 12-month period”.
The decision means Amusan would be allowed to participate and defend her women’s 100m hurdles titles at the 2023 World Athletics Championships billed to hold in Budapest, Hungary, from August 19 to 27.
However, Brett Clothier, head of AIU, said the body will review the reasoning in detail and decide whether to exercise its right of appeal to the Court of Arbitration for Sport (CAS) within the applicable deadline.
