Los Angeles, California (CNN) -- Michael Jackson's mother filed a lawsuit Wednesday accusing AEG Live of causing her son's death by pushing him to rehearse for his comeback concerts despite poor health. Katherine Jackson's suit, filed in Los Angeles Superior Court, claimed that the concert production company controlled Jackson's health because it hired and directed Dr. Conrad Murray. Murray faces trial on an involuntary manslaughter charge for administering drugs to the pop star that the coroner ruled caused Jackson's death in June 25, 2009. The suit claims that Murray was "selected by, hired by, and controlled by AEG," a worldwide concert promotion and production company.

"Rather than react reasonably and relax the rehearsal schedule so Michael Jackson could recuperate from his physical problems, @placeholder insisted that he attend every rehearsal in a grueling schedule, threatening that if he missed even one more, they would cancel the tour."

The company "should have known that it was jeopardizing Jackson's health and safety by assuming control over the doctor-patient relationship between Jackson and Murray, and by directing and influencing @placeholder to act without regard to medical safety standards," it said.
