Michael Jackson's mother and his three children have filed a civil lawsuit on Wednesday against the promoters of a series of planned concerts before his death last year. The lawsuit said Jackson's death on June 25, 2009 was due to the action and inaction of the promoters of the concerts.

The lawsuit filed by Katherine Jackson in Los Angeles Superior Court accuses promoter AEG Live putting its desire for massive profits over the health and safety of the super star. It alleged that AEG was liable for the desperate actions of Jackson's personal physician and that the promoter had failed to provide proper life-saving equipment for Jackson. His death was due to negligence, breach of contract and fraud.

The suit claims that Jackson appeared drugged and disoriented at rehearsals of the concert. Also, he was shivering on June 24. It also claimed that AEG was aware of his condition but did not postpone any rehearsals or alter his grueling schedule.

The civil action also seeks damages for emotional distress on behalf of Jackson's oldest son, Prince. Jackson's son witnessed his father dying and has suffered great trauma and severe emotional distress.

A spokesman for privately held AEG Live, a subsidiary of the Anschutz Entertainment Group, however said he had not seen the lawsuit and could not comment.

The 50-year-oldThrillersinger died of cardiac arrest in Los Angeles last year after returning from rehearsals just days before the planned 50 London concerts.

Los Angeles coroner's officials have ruled Jackson's death a homicide and said he died because of a powerful anesthetic used as a sleep aid, as well as other sedatives and painkillers.

Katherine Jackson's lawyer stated that the purpose of this lawsuit was to prove to the world the truth about what happened to Michael Jackson, one last time.

The superstar's personal physician Dr Conrad Murray, who was hired by AEG Live, has pleaded not guilty to a charge of involuntary manslaughter and is awaiting trial in Los Angeles.

Jackson's family has previously expressed disappointment at the criminal charge against Murray, saying it does not go far enough. The singer's father Joe in June filed a wrongful death lawsuit against Murray but did not name AEG.
