The anger and passion between the six Jackson lawyers and AEG's Putnam was evident with personal charges of bad ethics flying from both sides in court Wednesday.

"I've never seen anything like it in my career," Jackson lawyer Brian Panish said. "They think they can just smirk around and make these defamatory statements without evidence."

The documents made public in the Times story are not the most damaging to AEG that were uncovered, Boyle told CNN.

"We can assure you that we are in possession of documents that make for an extremely compelling story in the wrongful-death case, and that completely support the plaintiffs' claims," he said.

It was unusual for the 82-year-old Katherine Jackson to attend such a hearing, suggesting the case is also very personal for her.

The revelations from the leaked e-mails including one written by Randy Phillips weeks after Jackson's death in which the president of AEG Live -- the concert-promotion branch of AEG -- called it "a terrible tragedy," but adding "but life must go on."

"AEG will make a fortune from merch sales, ticket retention, the touring exhibition and the film/dvd," Phillips wrote. In fact, AEG Live was allowed to sell Jackson tour merchandise and share in the profits from the documentary "This Is It," produced from rehearsal video.

The e-mails suggest AEG Live's president saw Jackson's problems first-hand the day the pop star was to appear at the O2 Arena to publicly announce the shows.

"MJ is locked in his room drunk and despondent," Phillips wrote in the March 5, 2009, e-mail to AEG Live's parent company, the paper reported. "I (am) trying to sober him up."

"I screamed at him so loud the walls are shaking," Phillips wrote. "He is an emotionally paralyzed mess riddled with self-loathing and doubt now that it is show time."

The promoter blamed London traffic when Jackson was 90 minutes late for the announcement that day.

"He's as healthy as he can be -- no health problems whatsoever," Phillips told CNN two months later to refute reports Jackson's health was threatening the concerts.

The Los Angeles Times story, however, said the e-mails indicated major doubts about Jackson's ability to perform.

"We cannot be forced into stopping this, which MJ will try to do because he is lazy and constantly changes his mind to fit his immediate wants," AEG Live executive Paul Gongaware e-mailed to Phillips.

Jackson's missed rehearsals in June triggered concerns in e-mails that he was slow in learning his dance routines and would have to lip-sync on stage, the newspaper reported.

"MJ is not in shape enough yet to sing this stuff live and dance at the same time," one e-mail from the show's music director read, the paper reported.

A production manager wrote: "He was a basket case. Doubt is pervasive."

A loud warning from show director Kenny Ortega, who worked closely with Jackson on previous tours, came in mid-June, just over a week before his death. Ortega wrote to Phillips that Jackson had "strong signs of paranoia, anxiety and obsessive-like behavior" and suggesting they bring a "top psychiatrist in to evaluate him ASAP."

"It is like there are two people there. One (deep inside) trying to hold on to what he was and still can be and not wanting us to quit him, the other in this weakened and troubled state," Ortega wrote. "I believe we need professional guidance in this matter."

Ortega testified at Murray's trial about his concerns about Jackson's frail condition and missed rehearsals. It resulted in a meeting six days before Jackson's death in which Murray assured the promoters he would have Jackson ready for rehearsals that next week.

An e-mail from Phillips after that meeting said he had confidence in Murray "who I am gaining immense respect for as I get to deal with him more."

"This doctor is extremely successful (we check everyone out) and does not need this gig, so he (is) totally unbiased and ethical," Phillips' e-mail said.
