EXPUNGEMENTS IN CALIFORNIA
Contrary to belief and the true definition of the word expungement, California law does not provide one to fully erase a conviction. For example, firearm / gun rights are not restored with an expungement.
What A California Expungement Actually DoesThe California expungement law allows you to withdraw a plea or set aside a verdict, but the expungement does not erase the conviction from your record. You are still considered to have been convicted if you get in trouble with the law again. The concept is merely that you are released from many penalties resulting from the offense. Therefore, a California expungement relief doesn't expunge the record, it is only intended to mitigate some of the consequences of the conviction, i.e. the conviction is hidden from most employers, schools, etc. But in licensing situations you still need to admit to the conviction.
Vacating Convictions Based Upon Constitutional ViolationsA conviction can be vacated based upon a constitutional violation. In such instances, the court's authority to grant relief includes the inherent power to grant post-judgment motions to vacate a guilty plea. The writ of error coram nobis is one example of a non statutory, common law remedy whose purpose is to secure relief, where no other remedy exists, from a judgment rendered while there existed some fact which would have prevented its rendition if the trial court had known it and which, through no negligence or fault of defendant, was not then known to the court.
