Isaac Frost, 28, ranked 1,515 in singles, was found to have failed to co-operate with the TIU by refusing a request to supply his cell phone for analysis during the investigation.
As a result, he served a period of provisional suspension between 3 October 2013 and 4 September 2014, for failing to co-operate. Hearing officer McLaren concluded that no additional suspension or any fine should be imposed. Mr Frost is free to compete in any professional tennis event.
