California's medical board has once more implored a judge to suspend the license of the doctor who was at fault for Michael Jackson's death.

The existing prohibition on Dr. Conrad Murray's use of anaesthetics is insufficient, according to a brief submitted by the state attorney general's office.

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

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

Ed Chernoff, Murray's lawyer, said that a response will be given to the court later this week.

Murray will be returning to the court on Monday. He has pleaded not guilty to involuntary manslaughter with regards to Jackson's death due to anaesthetic propofol and other drugs.

His medical license would probably be the foremost issue in the hearing.

He was previously defended by his lawyers, saying that they deem it unnecessary to void Murray's license in California because he does not practice in the state. They also said that a suspension may also cause him to be unable to practice at his clinics in Nevada and Texas, where he also has licenses.

The Texas Medical Board in April prohibited Murray from applying propofol or any anaesthetic agent.

His medical license in Nevada may also be revoked due to child support payments that are overdue.
