Chris Brown lost a bid to delay a preliminary hearing in his assault case, which his attorney argued should wait for a related California Supreme Court decision. Brown's attorney, Mark Geragos, filed an appeal earlier this month to try to delay the R and amp;B singer's preliminary hearing, now scheduled for June 22. Two justices from California's Second District Court of Appeal signed an order Wednesday rejecting the arguments. Brown is accused of beating then-girlfriend Rihanna after a pre-Grammy party in February. Schnegg will decide at the preliminary hearing later this month whether there is enough evidence to continue the case against Brown. Rihanna could be called as a witness during that hearing.
