Hylton, winner of a 4x400 metres relay bronze medal at the 2011 World Championships in Daegu, claimed that he had been notified of his provisional suspension after allegedly declining to provide a sample during testing last April.

He was accused of violating Article 2.3 of the Jamaica Anti-Doping Commission (JADCO) Anti-doping Rules 2015 relating to "evading, refusing or failing to submit to sample collection".

But the 28-year-old insisted that he had not been properly informed about the test and only discovered anything about it after leaving the stadium.

A JADCO Disciplinary Panel upheld the decision and ruled that he had not violated any rules.

No specific explanation as to why they reached their decision has yet been given, however.

“JADCO has not discharged its burden of proving that Riker Hylton committed an anti-doping rule violation under Article 2.3 of the JADCO Rules, 2015 to the comfortable satisfaction of the panel," they ruled.

It was claimed that unveiling further information would be a breach of rules to do so without the consent of the athlete.

Hilton, who had been provisionally suspended since February, is not competing at the International Association of Athletics Federations World Championships starting here today, but is now free to return to competition.

It follows the clearing of Commonwealth 400m hurdles champion Kaliese Spencer In June after she had been accused of the same offence.
