Michael Jackson 's mother, Katherine Jackson , has lost her bid for a new trial in her wrongful death lawsuit against AEG Live, the promoter of the King of Pop's aborted This Is It tour, according to TMZ .
The Jackson family matriarch had argued the verdict form given to the jury in last year's trial was confusing. A Los Angeles judge disagreed on Monday.
Jackson is expected to file an appeal with a higher state court.
Last October, the trial jury agreed that AEG Live hired Michael's doctor, Conrad Murray , but rejected the claim that Murray was "unfit or incompetent to perform the work for which he was hired."
Murray was convicted of involuntary manslaughter after giving Michael a fatal dose of the powerful anesthetic propofol. He was released from jail in October after serving two years of a four-year sentence.
