Court records show a petition filed by Brown's attorney to delay the crucial hearing was denied on Wednesday.
Brown's lawyer, Mark Geragos, had asked the state's high court last week to intervene in the R&B singer's felony assault case. An appeals court had already rejected a similar request.
Brown is due back in court on Monday for a preliminary hearing, after which a judge will decide whether there is enough evidence for his case to go to trial.
Brown was arrested in February on suspicion that he beat his then-girlfriend, Rihanna. The 21-year-old Barbados-born singer could testify during the hearing.
