If Mel Gibson ever has to fill out an employment application ... he can honestly say he has not been convicted of a violent crime ... because his battery conviction in the Oksana Grigorieva case has been expunged.
A judge has officially removed the conviction from Mel's record ... after he successfully completed his 3 years probation.
TMZ broke the story ... the paperwork had been filed to erase the conviction for hitting Oksana in the mouth and knocking out 2 veneers.
Mel has done his 16 hours of community service and 52 weeks of counseling.
So Oksana is officially out of his life, except for the fact that she'll never be out of his life because they had a kid together.
