Gibson’s lawyer requested the dismissal after the star successfully completed the terms of his probation.

The star had been ordered to perform public service work and attend Alcoholics Anonymous for three years.

Gibson’s arrest sparked outrage after a leaked police report quoted him making anti-Semitic comments to the arresting officer in California, who was Jewish.

He has since repeatedly apologized for the remarks, saying his outburst did not reflect his true views.

Gibson had pleaded no contest to driving 87mph (140kph) with an open bottle of tequila in his hand. He also had 0.12 percent blood alcohol content, where the legal limit in California is 0.08.

As a first-time drink-driving offender, Gibson was eligible to have his conviction expunged after fulfilling his probation and maintaining a clean driving license.

Although it has been removed, the conviction could still expose the actor to more serious charges if he is ever arrested again for driving under the influence.

Gibson did not appear at the Los Angeles Superior Court for the ruling.
