The judge presiding over the Michael Jackson family's wrongful death lawsuit against AEG rejected the concert promoter's arguments that family members were the source of leaked emails in the case.
AEG lawyers accused Michael Jackson's three children, his mother and their lawyers of giving the emails to a newspaper reporter in violation of the judge's order that they remain under seal.
"It is clear that only one entity could have done it," AEG lawyer Marvin Putnam said in a hearing last month.
Jackson family lawyers became furious in court, pointing out that AEG was accusing 10-year-old Blanket Jackson, the youngest of the children.
"What's the idea, that Blanket Jackson got some documents and copied them and somehow walked them from Calabasas to Harriet Ryan?" attorney Kevin Boyle said, pointing to Putnam.
Jackson lawyers denied anyone associated with their legal team or their clients leaked the emails, and suggested that AEG lawyers may have done it themselves as a set up.
Los Angeles Superior Court Judge Yvette Palazuelos issued her ruling on the question this week.
The communications, published two months ago in the Los Angeles Times, revealed the promoter had doubts about Jackson's health and his ability to be ready for his "This Is It" concerts several months before his death.
AEG wanted the judge to punish Katherine Jackson and the children -- Prince, Paris and Blanket -- by not allowing their lawyers to use the e-mails to convince a jury in a trial set for next April that the company contributed to the pop star's death.
Jackson died of an overdose of a surgical anesthesia in combination with sedatives on June 25, 2009, according to the Los Angeles County coroner. Dr. Conrad Murray, who was hired to be Jackson's personal physician as he prepared for the shows, was found guilty last year of involuntary manslaughter in his patient's death.
The Jackson suit contends that AEG contributed to the pop star's death by pressuring him to prepare even though the promoters knew he was in a weak condition and by its hiring and supervision of Murray.
"MJ is locked in his room drunk and despondent," AEG executive Randy Phillips wrote in a March 5, 2009, email, the day Jackson announced the tour plans. "I (am) trying to sober him up."
Reporter Harriet Ryan has refused to disclose her sources, although Howard Mann -- who was once Katherine Jackson's partner in a book venture -- has acknowledged that he gave the reporter a box of documents for her story.
Days after the emails were published, AEG dropped its claim against a Lloyds of London underwriter for payout of a $17.5 million insurance policy on Michael Jackson.
The insurer contended AEG hid Jackson's health problems and failed to respond to repeated requests for his medical history when applying for insurance for the 50 shows scheduled for London's O2 Arena.
The Michael Jackson estate, which controls Michael Jackson Company LLC, is still pursuing the insurance payout.
Perry Sanders, who is Katherine Jackson's personal attorney, told the judge that the Jacksons had no motive to leak the emails.
"Like we would go and blow up our own case against Lloyds of London?" Sanders said. "Our client and all the plaintiffs in this case are actually the ones who would receive the money."
Sanders also noted that AEG had failed to disclose the emails to the Lloyds of London lawyers despite a legal requirement to do so.
While publication of the emails might have made AEG look bad, they were "extremely negative against Michael Jackson," painting him "as a basket case," Jackson lawyer Deborah Chang said.
