LOS ANGELES -- A Los Angeles court has vacated Mel Gibson's misdemeanour domestic violence battery conviction in a case filed after a highly publicized fight with his ex-girlfriend.

The dismissal was finalized Monday by Superior Court Judge Deborah Brazil, and her order was released Friday.

Gibson pleaded no contest in 2011 to one count of misdemeanour spousal battery of his former girlfriend Oksana Grigorieva. He was sentenced to three years of probation, domestic violence counselling and two days of community service.

The Oscar-winning director completed the terms of his sentence within a year.

He was accused of striking Grigorieva during a fight in January 2010, although she did not report the incident to authorities until months later. By then, the pair was locked in a custody battle over their infant daughter.
