According to an AAP report, Gurpreet Singh was found guilty last year in the Brisbane District Court of raping a 24-year-old woman who had passed out in his cab while he was driving her home from a hotel in Fortitude Valley.
He was sentenced to eight years' jail for that offence.
The accused took their cases to the Court of Appeal in Brisbane, where he argued the verdict could not be supported by the evidence.
Singh's lawyers argued the woman had consented to having sex.
In written judgements published today, the Court of Appeal dismissed his case, finding the verdict were consistent with the available evidence.
