Joe Jackson's Lawyer Prepares Legal Case Against Michael's Live Promoters

Jackson suffered a cardiac arrest and died last June (09), just days before he was due to kick-off the mammoth This Is It series of tour dates.

His death has been ruled a homicide and the singer's medic, Dr. Conrad Murray, has pleaded not guilty to a charge of involuntary manslaughter for administering the drug that ultimately led to his demise.

But Joe Jackson wants his son's concert bosses held accountable and his lawyer, Brian Oxman, is set to lodge a complaint with the United States Attorney General, alleging AEG executives were not in compliance with the Americans with Disabilities Act.

Oxman alleges AEG heads knew about the Thriller star's struggle with prescription drugs, deeming him effectively disabled, but continued to pressure Jackson to stick to a gruelling rehearsal schedule in preparation for the London shows.

Oxman is also planning to file a complaint with the Medical Board of California, claiming AEG bosses had such tight control of the singer's medical treatment, it became the unauthorised practise of medicine, reports TMZ.com.

The attorney tells the website he will lodge the complaints with the government agencies this month (Jun10), before the first anniversary of Jackson's death (25Jun10).
