It seems that the practice of running criminal background checks on potential jurors by Hamilton County, Ohio prosecutors has prompted a request for a new trial. According to the article, Jurors Checked for Criminal Past:
Timothy Jordan, charged with aggravated murder, asked a judge this week for a new trial on grounds that Allen’s office improperly used computer records at the federal National Crime Information Center to disqualify two black jurors.
Judge Mark Schweikert denied the defendant’s request for a mistrial in a case that is bringing the practice of performing criminal background checks on jurors to light. The request for a mistrial came after defense counsel learned the prosecutors had used NCIC, the federal criminal records database, to disqualify two African-American jurors. The jurors had lied about their criminal past.
