 Expungement may restore gun rights in some states but will not be sufficient to restore firearms rights in others.Seeking restoration of firearm rights may requires that the petitioner specifically request restoration of those rights, or may require that the petitioner obtain a pardon that fully restores his or her civil rights.California's expungement law permits someone convicted of a crime to file a Petition for Dismissal with the court to re-open the case, set aside the plea, and dismiss the case.
