The New Jersey Supreme Court's ruling is due Tuesday morning.
Prosecutors say the slur was uttered in 2002 by a senior officer who did not testify at /*Jayson Williams*/' first trial and has since retired.
Williams' attorneys have sought documents relating to the investigation of the slur and interviews with those who were present.
Williams was acquitted of aggravated manslaughter in 2004 but convicted on four counts of trying to cover up the 2002 shooting of hired driver Costas Christofi. The jury deadlocked on a reckless manslaughter count.
