Los Angeles ( CNN ) -- The judge who presided over the Michael Jackson wrongful-death trial last year has tentatively rejected the Jacksons ' request for a new trial.. The six-month-long trial ended in October with a victory for AEG Live , the concert promoter Jackson 's mother and children had claimed was liable for his death because it hired , retained or supervised the doctor convicted of involuntary manslaughter in the death . Lawyers for mother Katherine Jackson argued that the verdict form used by the jury was faulty and that the judge erred by refusing to let them pursue a negligence claim independent of the hiring case . Their motion for a new trial filed in December included sworn statements from four of the 12 jurors saying they feel cheated by the outcome , which they blame on a misleading verdict form . Jackson died from an overdose of the surgical anesthetic propofol on June 25 , 2009 , which Dr. Conrad Murray told police he used to treat the pop icon 's insomnia as he prepared for a tour produced by AEG Live .

Los Angeles County Judge Yvette Palazuelos issued a tentative ruling saying that she did not err in her decisions on the verdict form or with the dismissal of the negligence claim . She head oral arguments on Friday and is expected to make a final decision soon . Jackson lawyers have indicated that they will appeal the jury 's verdict . AEG Live lawyers filed statements from seven other jurors saying they were not confused by the verdict form . The jurors cited by the Jackson motion used the words `` stunned , '' `` upset '' and `` shocked '' when they were told they had to stop deliberations after a majority agreed that the answer was `` no '' to the second question on the verdict form : `` Was Dr. Conrad Murray unfit or incompetent to perform the work for which he was hired ? '' One juror called the question `` a trap that prevented us from deliberating on the real issues of the case . '' `` After sitting through almost six months of the trial in this case , I believed that Mrs. Jackson had proven her case against AEG LIve , '' another juror said . `` Despite this fact , I had no way of voting in favor of the plaintiffs because of the way that the verdict form was worded . '' Jackson lawyers , in their arguments for a new trial , contended that Palazeulos erred by denying their request to add the words `` at any time '' to the second question .
