California's medical board has again asked a judge to suspend the licence of the doctor charged over pop star Michael Jackson's death.

The state attorney general's office argued in a brief filed on Monday that the current ban on Dr Conrad Murray using anaesthetics was insufficient.

"While the defendant asserts that he will not practise in California, there is no legal bar to him changing his mind and engaging in practice in this state," the filing states.

It also argues "it is not just his 'prescribing' practices that are in question, but his fundamental judgment and skill as a physician".

Dr Murray's lawyer Ed Chernoff said he would file a response to the court later this week.

The doctor, who is due back in court on Monday, has pleaded not guilty to involuntary manslaughter in the death of the 50-year-old singer from the anaesthetic propofol and other drugs.

Dr Murray's medical licence is likely to be the dominant issue of the hearing.

His lawyers have previously argued it is unnecessary to revoke his California licence since he does not practise in the state. They also warned that a suspension would have a domino effect leading to his inability to practise at his clinics in Nevada and Texas, where he is also licensed.

In April, the Texas Medical Board restricted Dr Murray from administering propofol or any anaesthetic agent normally administered by an anaesthesiologist.

His medical licence in Nevada is also at risk because of unpaid child support payments.

Last month, the cardiologist stabilised a woman who fell unconscious and had a weak pulse on a US Airways flight from Houston, Texas.
