Brown's attorney, Mark Geragos, had asked the state's highest court to intervene after the 2nd District Court of Appeal turned down his request to obtain personnel files of Los Angeles police personnel involved in the case prior to his client's preliminary hearing.
Geragos turned to the appellate court -- then the state's high court -- after a Los Angeles Superior Court judge last month denied his motion for the files.
At the May 28 hearing, Judge Patricia Schnegg told Geragos he could seek the information again after the preliminary hearing.
Brown, 20, was charged March 5 with one felony count each of assault by means likely to produce great bodily injury and criminal threats.
He is accused of assaulting and threatening his then-girlfriend during an argument that began around 12:30 a.m. Feb. 8, while the couple was in a rented Lamborghini on North June Street near First Street.
At the time, the two were en route to a home in the Hancock Park area following a pre-Grammy Awards party.
Brown surrendered to police hours later and was freed after posting $50,000 bail.
