Murray lawyer Valerie Wass, who unsuccessfully objected to the deposition, said the decision disappointed her. Wass said she would advise Murray to invoke his Fifth Amendment right to not answer questions.

“But Dr. Murray has a mind of his own,” Wass said. “If he decided to answer a question, those parties don’t know what he’s going to say.”

The videotaped deposition is set to take place on March 18 in the Los Angeles County jail where Murray has been serving his sentence since November 2011.

Murray, who was the pop superstar’s personal physician, has never been questioned under oath about Jackson’s death. He did not testify at his trial.
