Katherine Jackson has just filed legal docs claiming AEG was well aware ... there were life-threatening activities going down at Michael Jackson's house ... yet the company turned a blind eye.
Katherine is challenging AEG's motion to dismiss the wrongful death lawsuit against the company.
In her docs, Katherine says AEG retained Dr. Conrad Murray for an "exorbitant salary of $150,000 monthly," and in return Murray agreed to "get Jackson to attend rehearsals and perform."
Katherine's lawyers claim it should have been obvious to AEG when Murray requested CPR equipment at MJ's home that "the medical treatments being administered risked stopping Jackson's heart and breathing."
The lawyers claim, "AEG should have known that the course of treatment being administered by Dr. Murray was unorthodox and unsafe."
