KEY POINTS:
Details of Martina Hingis' positive dope test at Wimbledon this year might never be revealed if an anti-doping tribunal rules in her favour, the International Tennis Federation (ITF) said.
Former world number one Hingis announced her retirement from professional tennis after saying she had tested positive for cocaine, though she denied taking the drug.
The London-based ITF is in charge of administering dope tests in tennis and a spokesman said its rules prohibited comment on or publication of a positive test until any appeals had run their course. Unlike in athletics, where officials release a name as soon A and B samples have been analysed even if the athlete maintains his or her innocence, the ITF publishes details only after a player has been to an anti-doping tribunal and lost the case.
If the tribunal finds in the player's favour details are never revealed. Hingis made her announcement after she said her lawyers advised her the fight to prove her innocence could go on for years.
The five-times grand slam champion from Switzerland said she found the accusation "so horrendous, so monstrous, that I have decided to confront it head-on by talking to the press".
The 27-year-old said her legal representative had discovered various inconsistencies with the urine sample taken during Wimbledon and felt doping officials mishandled the process.
The Hingis case has parallels with that of Briton Greg Rusedski in 2004, who also chose to announce he had failed a test for nandrolone and was later cleared by a tribunal.
