If a juror fails to disclose or misrepresents potentially important information during jury selection, a new trial can be given to the Defendant if the Defendant can show to the court that the Juror concealed material information during "Voir Dire".

In this case the Judge, during jury selection asked if any jurors knew any of the people on the Prosecutions witness list and the Defense's witness list, he then proceeded to read the lists out loud for the jurors.  A juror (a local bar owner) didn't mention when the witness list was read out loud that he knew two of the Defenses witnesses.  This juror played on a pool league with them for 10 years. One of the Defenses witnesses being another local bar owner later signed an affidavit stating he in fact knew the juror, very well since the two of them are bar owners in Springfield and played pool together on the same team.  The other witness that the juror knew was Denny's nephew who also played on the same pool league. This juror also played on that pool league with Denny's other brother. This brother signed an affidavit after trial stating that two weeks after Tony died he had a conversation with the bar owner/juror during a pool game about Tony's death.  This juror not once spoke up during trial about any of this. 

Records from the pool league were obtained after trial which had showed that the juror and the witnesses for the Defense, and Denny's brother had all played pool together for a number of years.  This was all brought to the Judge's attention at a hearing after trial.  The Judge did nothing and said that the relationship was "harmless". 

This juror failed to disclose potentially important information during jury selection, and a new trial should be given to Denny.
