Former New Jersey Nets center Jayson Williams listens to testimony during his manslaughter trial April 20, 2004 in Somerville, New Jersey.
Williams was convicted on four counts of covering up the shooting of a hired driver at his central New Jersey mansion more than seven years ago.
In 2007, the Hunterdon County Prosecutors Office disclosed that an investigator used a racial slur in reference to Williams in 2002.
Williams' attorneys argued in court Monday that the failure to disclose the remark before the trial, along with other actions by a former prosecutor, constitute misconduct.
The state argues that the slur had no effect on the cover-up convictions.
Williams is awaiting retrial on a reckless manslaughter count.
