Michael Jackson’s former concert promoter AEG Live is withdrawing a $17.5 million (€13.5 million) insurance claim in the 2009 death of the pop star amid revelations in leaked e-mails that show company executives were concerned about his stability ahead of his planned London comeback tour.

Attorneys involved in the case denied that AEG Live’s move was related to the publication of the leaked e-mails by the Los Angeles Times on September 2.

Jackson died in June 2009 aged 50 from an overdose of the powerful anesthetic propofol and sedatives.

Last year, a Los Angeles jury convicted the Thriller singer’s physician, Conrad Murray, of involuntary manslaughter but heard that Jackson was taking a cocktail of sleep aids and prescription medications.

AEG Live, the concert division of privately held Anschutz Entertainment Group (AEG), had filed a claim seeking a $17.5 million insurance payment from Lloyd’s of London for losses they incurred in up-front costs for Jackson’s This Is It sell-out shows that were to start in London in July 2009.

Lloyd’s later filed a lawsuit against AEG Live in Los Angeles Superior Court, seeking a declaration that the insurance company did not owe the money.

Marvin Putnam, an attorney for AEG, said the company no longer needed the $17.5 million because it was reimbursed by the Jackson estate for its concert-related losses and that it informed Lloyd’s in June that it was withdrawing its claim.

Attorneys in the case told a judge on Monday that as a result they expected AEG Live to be dropped from the case, Dr Putnam said. That has not yet officially happened, he said.

The insurance dispute is one of two major court cases stemming from Jackson’s death.

The other is a wrongful death lawsuit filed by the Thriller singer’s mother, Katherine Jackson, against AEG Live in which she accuses the company of being responsible for medical decisions made by Murray.

That case is scheduled for trial next year.
