The SuperSport United player was going to make the application this morning, but the matter was again postponed, this time until Thursday, as magistrate Vincent Pienaar is ill.
Moon's defence advocate Naren Sangham said yesterday he is not convinced that the state witnesses' evidence is solid enough to secure a conviction, according to The Sowetan.
The player is in court following an incident on June 30, 2009, when he allegedly hit domestic worker Mavis Ncube while driving his Mercedes-Benz. Ncube later died of her injuries in hospital.
Moon has been charged with murder, alternatively attempted murder, drunken driving, alternatively driving while an excessive amount of alcohol was in his blood, reckless and negligent driving, alternatively inconsiderate driving.
The prosecution has had continual problems with the availability of witnesses, and last December Sangham protested, saying: "The delay is inconveniencing my client and his career because this trial attracts a lot of media attention.
"It seems there are some parts of the State that cause these delays deliberately for reasons unknown."
Moreover, in March Sangham called for the accident report of the incident to be disregarded by the court, saying it was based on unreliable statements and witnesses.
