Michael Jackson's doctor will appear in court on manslaughter charges today (04.01.11).

Dr. Conrad Murray - who was the singer's personal physician when he died of acute Propofol intoxication in June 2009 - will face a preliminary hearing at Los Angeles Superior Court over the next two weeks so Judge Michael Pastor can determine if there is enough evidence to hold a full trial.

During the hearing 30 witnesses - mostly medical experts - are expected to be called to testify, however, Michael's family will not be asked to give evidence.

Dr. Murray has pleaded not guilty to involuntary manslaughter with his defence lawyer J. Michael Flanagan admitting his client gave the pop legend Propofol but claiming it was just 25 milligrams, much less than was found in his system.

It is understood the physician's legal team will claim Michael awoke and gave himself the lethal dose of the drug while Dr. Murray was out of the room if the case does go to a full trial.

If convicted the 52 year old faces up to four years in prison.
