The case dismissal was granted on Monday by Jackson's father.The filings do not elaborate on a reason, but two lawyers handling the case were recently ruled ineligible to practise law in California.
"It's good finally that this case is dismissed and gone," Murray's lawyer Charles Peckham said. "It's pretty clear that Joe Jackson intelligently and smartly dismissed this case so he, his wife and children can focus on Michael Jackson's life instead of the circumstances of his death."
He said Murray, who is jailed and appealing against his involuntary manslaughter conviction, remained pained by Jackson's death in June 2009 and felt sorry for his family. "His heart goes out to them," Mr Peckham said.
