Dr. Conrad Murray defended his appellate lawyer from "a slew of disparaging remarks" just days before she files the appeal of the doctor's involuntary manslaughter conviction in Michael Jackson's death.
CNN has obtained sections of that 300-page appeal, including the defense argument that the trial judge erred by not allowing the testimony of Dr. Arnold Klein, a dermatologist the defense contended addicted Jackson to Demerol in his last weeks.
Murray's appeal, which will be filed Monday, also argues that prosecutors never proved Jackson was hooked up to an IV drip of the drug that killed him. The defense theory was that Jackson had administered the fatal dosage himself while the doctor was away.
The coroner ruled that Jackson died from an overdose of the surgical anesthetic propofol in combination with sedatives on June 25, 2009. Murray told investigators he used propofol to induce sleep because Jackson was suffering from insomnia.
Murray served as Jackson's personal physician as the pop icon prepared for 50 shows that were to debut in London in July 2009, but his patient was fighting a battle for sleep between rehearsals.
A wrongful death lawsuit filed by Jackson's three children and his mother is set for trial next month. The family accuses concert promoter AEG Live of liability in his death by hiring and supervising the doctor, who was convicted of involuntary manslaughter in November 2011.
Murray takes a side in lawyer dispute
Murray -- during a phone call to CNN Saturday from the Los Angeles County jail where he's been held since he was sentenced to four years in prison -- said he was "impelled to stand up for" attorney Valerie Wass, who has been involved in a personal dispute with Murray's trial lawyer Michael Flanagan.
Flanagan was helping Wass, who wrote the appeal, until the two lawyers were involved in a jailhouse argument last January. Flanagan dropped Murray as a client after the incident, but the appeals court later ordered him to respond to requests from Wass for case files, which she said he had withheld.
Murray, who witnessed the January incident between his attorneys, issued a strong statement of support for Wass in his call from jail.
"In recent weeks, I became keenly aware that a slew of disparaging remarks and personal information about my appellate attorney, Valerie Wass, were unjustly released to the media and the public," Murray said. "Because of this injustice, I am impelled to stand up for this woman, for whom I have the utmost respect and confidence."
Wass completed work on the appeal even though "with the blink of an eye, all of her promised assistance vanished; they abandoned ship," Murray said.
Responding to CNN on Sunday, Flanagan said he had no comment.
"Although she needed help, she did not quit, did not jump ship, nor did she succumb to pressure while others abdicated their responsibilities," he said. "She held steadfastly to her professional and moral conduct, which was bolstered by her amazing mettle of mind and spirit."
Murray said Wass "stood up for me amidst a most arduous and challenging series of obstacles, and whose loyalty remains indisputable. It is my belief that she took a personal hit for me, and I want to let her know that I'll forever be grateful."
Murray's appeal: Jackson's Demerol addiction
Although Murray could be freed in about seven months, he is seeking to clear his name and get his medical license back by having his conviction overturned on appeal.
The appeal contends that Los Angeles Superior Judge Michael Pastor wrongly prevented Murray's trial lawyers from making their case that Jackson was going through withdrawal from a Demerol addiction the day he died.
"The reason it sought to prove that Jackson was going through Demerol withdrawal on June 25th was to show his state of mind -- specifically, that his resulting physiological and psychological state, along with the pressure he was under from preparing for the upcoming tour, rendered him so desperate for sleep that he would take the extraordinary action of self-administering propofol when he was outside the presence of appellant," Wass writes.
Defense experts testified at the trial that Jackson's insomnia could have been caused by the withdrawal.
The defense wanted Klein and two staff members to testify about Jackson's 23 visits to their Beverly Hills clinic in the three months before his death, including five in June 2009. Jackson was given Demerol during those visits, the last time on June 22, three days before he died.
"Michael Jackson could not sleep because of the Demerol," the defense said in pretrial arguments. "Dr. Murray did not know that. But Arnold Klein did. Michael Jackson needed sleep because he was withdrawing and addicted, both addicted and withdrawing from Demerol. That's important to our defense. In fact, it's absolutely vital."
Pastor, however, ruled that testimony from Klein and his staff would be a "distraction and divergence" in the trial.
"The defense was also unable to prove whether Jackson was addicted to Demerol and going through withdrawal at the time he died, because experts in the case articulated they could not reach conclusions based only on reviewing Klein's records," Wass writes in the appeal.
If Klein or his staff had been allowed to testify at the trial, "It is reasonably probable that at least one juror on the panel would have found appellant not guilty of involuntary manslaughter," the appeal argues. "Accordingly, regardless of the applicable standard of review, appellant's conviction must be reversed."
