Closing arguments in the six-week case will begin tomorrow — one of the final steps before jurors begin deliberations.
Superior Court Judge Michael Pastor asked Dr Conrad Murray whether he intended to take the stand.
“Have you made up your mind,” Pastor asked.
Murray said: “My decision is I will not testify in this matter.”
“The court finds the defendant has knowingly, freely and explicitly waived his right to testify,” the judge said. “I certainly will respect that decision.”
Murray’s announcement was made outside the presence of jurors.
Defence attorneys rested their case after calling 16 witnesses. A total of 49 witnesses testified over 22 days of trial.
Prosecutors contend Murray gave Jackson a fatal dose of the anaesthetic propofol in the bedroom of the singer’s mansion. Defence attorneys claim Jackson self-administered the dose when Murray left the room.
The last witness was prosecution propofol expert Dr Steven Shafer who was called by prosecutors as a rebuttal witness to address a few points raised by previous testimony.
Murray has pleaded not guilty to involuntary manslaughter in Jackson's death on June 25, 2009. He could face up to four years behind bars and the loss of his medical license if convicted.
Murray’s decision against testifying came after hours of intense grilling by a prosecutor of Dr Paul White, an anaesthesia expert who has said he believes Jackson injected himself with the fatal dose of propofol when Murray left his bedside.
After asking only eight questions on Monday, Deputy District Attorney David Walgren got White to acknowledge that Murray had repeatedly violated the physician's standard of care.
White also told jurors that he would have never done what Murray was doing — giving Jackson propofol as a sleep aid.
