Michael Jackson's former doctor lost a bid in a California court to resolve a child support issue that threatens his Nevada medical license.

A Santa Clara County Superior Court commissioner rejected a bid Thursday by attorneys for Dr. Conrad Murray to obtain a court order relieving Murray of an obligation to pay about $16,000 in back child support to the mother of his 12-year-old son.

Authorities in Las Vegas had said that if Murray got the California court order, Nevada would stop efforts to revoke his medical license for failure to pay.

A hearing is set June 25 before a Family Court hearing officer in Las Vegas.

Murray told police he administered the anesthetic propofol to Jackson for insomnia. Murray has pleaded not guilty to a felony charge of involuntary manslaughter in the death of the pop star.
