Los Angeles (CNN) -- Michael Jackson's sexual molestation trial is "no-go territory" for defense lawyers in the trial of Dr. Conrad Murray, a judge ruled Monday. Los Angeles County Superior Court Judge Michael Pastor, however, will allow testimony from two doctors about what the defense contends was Jackson's request for the surgical anesthetic propofol, a drug the coroner ruled played a major role in his death. Defense lawyers appeared frustrated with the rejection of their witnesses, although they declined to speak to reporters about it as they left the downtown Los Angeles courthouse after Monday's hearing. Murray is charged with involuntary manslaughter in the June 25, 2009, death of Jackson, who would have turned 53 Monday.
